TDK Corporation presents an extended range of CeraLinkā¢Ā capacitors based on PLZT ceramic (lead lanthanum zirconate titanate). The low profile (LP) types for SMD soldering are now available with a voltage of 500Ā V and a capacitance of 1Ā ĀµF, or with 700Ā V and 0.5Ā ĀµF. The capacitors are characterized by their extreme volume efficiency and compactness. The dimensions of the variants with L-style terminal, for example, are 10.84Ā mm xĀ 7.85Ā mm xĀ 4Ā mm. Thanks to the compactness and the permissible maximum temperature of 150Ā Ā°C, these capacitors can, for example, be embedded as snubber capacitors directly into IGBT modules.
The new types with J-style terminal have an even more compact design, with dimensions of just 7.14Ā mm xĀ 7.85Ā mm xĀ 4Ā mm. One great advantage of the CeraLink LP types is their extremely low ESL of just 2.5Ā nH.
The CeraLink solder-pin (SP) type is available for higher capacitance values of 20Ā ĀµF and 10Ā ĀµF for the rated voltages of 500Ā V and 700Ā V, respectively. This type has a very low ESL of just 3.5Ā nH.
Thanks to their low parasitic effects, CeraLink capacitors are ideally suitable for converter topologies on the basis of fast-switching semiconductors such as GaN or SiC. Voltage overshoots and ringing when switching are significantly lower than with conventional capacitor technologies. Special requirements in terms of size, current capability and temperature resistance can also be accommodated very easily with CeraLink capacitors.
