The smallest version of the CeraLink is the SMD low-profile variant with a capacitance of 1 µF at a rated voltage of 500 V DC. It has dimensions of 4.25 mm x 7.85 mm x 10.84 mm. A further type with solder-pin contacts is also available. This 20-µF capacitor has a rated voltage of 500 V DC and measures 33.00 mm x 22.00 mm x 11.50 mm. Both types offer extremely low ESL values below 3.5 nH. The capacitors are designed for an operating temperature of -40 to +125 °C and can even withstand brief exposures to 150 °C.
A great advantage of the SMD low-profile CeraLink versions is that they can even be embedded in IGBT modules thanks to their compact dimensions. This results in a very low-inductance design, so that no significant overvoltages are produced when the semiconductors are switched.
Furthermore, samples are available for two further types: An SMD variant with a capacitance of 5 µF at 500 V DC and measuring 3.25 mm x 14.26 mm x 9.35 mm. The second type, which is fitted with solder-pin contacts, has a capacitance of 5 µF of 1000 V DC and dimensions of 33.00 mm x 22.00 mm x 11.50 mm.
