Suntan Capacitors

Ceramic capacitors have a solid body made of high-temperature, ceramic resistive material with bonded metal contacts.

Specifications Ceramic Capacitor:
Ceramic COG (NPO) - Ceramic COG (NPO) capacitors have a high Q, low K, temperature-compensated dielectric and stable electrical properties under varying voltage, temperature, frequency and time. They are suitable for low-lost circuits and for timing and tuning applications.

There are several unofficial, colloquial temperature coefficient designations for capacitors. The temperature coefficient is given as P for positive and N for negative, followed by a 3-digit value in ppm/°C. For example, P100 is +100 ppm/°C and N220 is -200 ppm/°C. The exception to this system is NPO where the letter “O” instead of the number “0” is used; however, the term NP0 is not uncommon. Both NPO and NP0 indicate that the capacitor is stable with temperature.

Ceramic X7R - Ceramic X7R (BX) capacitors have moderate K values and are temperature-stable. They exhibit moderate changes in electrical properties under conditions of changing temperature, voltage, and frequency. X7R capacitors are suitable for bypass, coupling, and frequency discrimination circuit applications. X7R capacitors exhibit no more than 15% capacitance deviation over a -55 °C to +125 °C temperature range.

Ceramic Z5U - Ceramic Z5U capacitors are Class III devices with a dielectric that exhibits a maximum capacitance change of +22% - 56% over an operating temperature range of +10 °C to + 85 °C.

AVX’s TAW series of fused tantalum capacitor protect against damaging high DC leakage currents at high currents. Short circuit failure mode protection is accomplished using an internal fuse connected in series with the capacitor.

When the fuse exceeds its current limit, the fused capacitor will fail safe by effectively removing itself from the circuit by creating a high resistance path of above 10MΩ. In some cases this can mean the difference between a total circuit loss and barely detectible performance degradation.

The TAW series tantalum capacitors are fully lead-free and RoHS compliant.

This November, our company will attend Electronica2008 in Munich, Germany. At this fair, we will strongly recommend our Tantalum Capacitor to visitors and customers from all over the world. Especially TS19 Dipped Tantalum Capacitor and and TS20 Chip Tantalum Capacitor will be our focus.  From the sales performance of 2008 first half year, the two Tantalum Capacitors bring us very good business and customers’ comment to the two series is satisfactory , these bring us more confidence to expand our market for Tantalum Capacitors all over the world, especially in Europe and in America.  

The lead spacing and form outline are very important in selecting your choice of dipped tantalum capacitor. Lead spacing is determined is offered in a few common spreads. They are indicated in the chart below.

There are some common outline forms used by the leading manufacturers of dipped radial tantalum capacitors. Some of these have names such as “hairpin” “hockey-stick” and “lock-in”. These are determined by the type of crimps in the leads.

These capacitors are made to specific case sizes. Some manufacturers offer a wider selection than others. For example AVX offers their TAP series of dipped radial tantalum capacitors in 15 case sizes while Sprague/Vishay offers their comparable 199D series in 6 sizes.

Since a dipped radial tantalum capacitor is polarized it is important to understand how these units are marked to ensure that they are inserted properly into the circuit. We have included charts they will show you how some of the leading manufacturers mark this style of capacitor along with the most common lead forms.

Some applications where you can use a dipped tantalum capacitor are bypassing, coupling, blocking, filtering and timing in wide range of commercial, industrial and military applications. Other types of capacitors that can be used for these applications are ceramic and film capacitors. Each dielectric has advantages and disadvantages. The tantalum advantages are higher capacitance values within a given package size and stability of capacitance with applied DC voltage.

Tantalum capacitors are a form of electrolytic capacitor. However, some forms of them are non-polar, containing two capacitors connected in series (negative to negative). In comparison with aluminium electrolytic capacitors, they are for similar capacitance and volume ratings generally more expensive, with lower effective series resistance. They usually have longer life, especially at moderately elevated temperatures. For surface mount devices, they are generally smaller.

Tantalums exploit the tendency of tantalum to form a protective oxide surface layer. They use tantalum powder, pressed into a pellet shape, as one “plate” of the capacitor with the oxide as the dielectric, and an electrolytic solution or conductive solid as the other “plate”. Because the dielectric layer can be very thin (thinner than the similar layer in, for instance, an aluminium electrolytic capacitor), a high capacitance can be achieved in a small volume. Because of the size and weight advantages, Tantalum Capacitor is useful in portable telephones, pagers, personal computers, and automotive electronics.

The multilayer ceramic capacitor has a many-layered dielectric. These capacitors are small in size, and have good temperature and frequency characteristics.This capacitor is used to bypass the high frequency to ground, Above about the Multilayer Ceramic Capacitor information content.

We offer these Disc Ceramic capacitor in a wide range of voltages and capacitance. They are Radial Lead type. Ceramic capacitors are used for blocking, by-pass and coupling of DC and signals to VHF range, pulse logic and timing circuits and for general purpose applications. Choose NP0 type when stability is of concern, such as in RF circuits. The monolythic ceramic are epoxy dipped. They are small in size and are used in VHF circuits, bypassing, and general purpose use. They are preferred over standard Ceramic capacitor for their small size and stability. The photo to the right both show a .1µf value at 50 volts. You can clearly see the size difference.

Ceramic capacitors are constructed with materials such as titanium acid barium used as the dielectric. Internally, these capacitors are not constructed as a coil, so they can be used in high frequency applications. Typically, they are used in circuits which bypass high frequency signals to ground. These Ceramic capacitors have the shape of a disk. Their capacitance is comparatively small, Above about the Ceramic Capacitor information content.

The Ceramic capacitor on the left is a 100pF capacitor with a diameter of about 3 mm.
The Ceramic capacitor on the right side is printed with 103, so 10 x 103pF becomes 0.01 µF. The diameter of the disk is about 6 mm.
Ceramic capacitors have no polarity. Ceramic capacitors should not be used for analog circuits, because they can distort the signal.

Ceramic capacitor offer a broad range of size vs. performance tradeoffs and are easily the most popular in numbers sold.  Ceramic capacitors are available from Ceramic capacitor are their relatively high dielectric constants.   This can vary from C0G with a K of up to 60, which has excellent electrical properties but is relatively large and expensive, to ceramics with Ks in the tens of thousands but with very poor electrical properties.  Large- value ceramics can replace electrolytic capacitors in high-frequency applications like switch-mode power supplies because of their lower ESR.  Ceramic capacitors are especially suitable for surface mounting due to their heat resistance, mechanical integrity, and the ability to make them in very small packages at low cost, for portable equipment.  This has greatly added to their usage.  To some extent ceramics are slowly displacing other types of capacitors. 

Cons: Low breakdown voltage means that the low-K ceramics (Class 1), the ones with the good electrical properties, have poor volumetric efficiency, and are usually found only in small values.  High-K ceramics (Class 2 and higher) have poor electrical properties, which are highly dependent on temperature, voltage, and frequency, plus a significant aging rate.  Unlike many other capacitors, ceramics have no self-healing mechanism.  This means that manufacturers must maintain a high level of quality control over the dielectric.  Ceramics are most cost affective in small sizes at present.  Very large ceramics are a bit of a challenge, especially in SMD.

Ceramic Capacitor HF use

Ceramic capacitors are suitable for moderately high-frequency work (into the high hundreds of megahertz range, or, with great care, into the low gigahertz range), as modern ceramic caps are fairly non-inductive compared to the other major classes of capacitors (film and electrolytic). Capacitor technologies with higher self-resonant frequencies tend to be expensive and esoteric (typically, mica or glass capacitors).

Ceramic Capacitor Knowledge

A ceramic capacitor is a two-terminal, non-polar device. The classical ceramic capacitor is the “disc capacitor”. This device pre-dates the transistor and was used extensively in vacuum-tube equipment (e.g., radio receivers) from c.a 1930 through the 1950s, and in discrete transistor equipment from the 1950s through the 1980s. As of 2007, ceramic disc capacitors are in widespread use in electronic equipment, providing high capacity & small size at low price compared to other low value capacitor types.
