CeraLink capacitors open new dimensions for power electronics systems based on SiC and GaN

TDK CeraLink capacitors are a highly compact solution for the snubber and DC links of fast switching converters, ideal for systems based on SiC and GaN semiconductors. These new capacitors are based on a PLZT ceramic material (lead lanthanum zirconate titanate). In contrast to conventional ceramic capacitors, CeraLink capacitors have their maximum capacitance at the application voltage.

Two designs are already in mass production:

  • LP series: Low profile for reflow soldering with capacitances from 0.25 µF up to 1 µF and rated voltages between 500 V DC and 900 V DC
  • SP series: For THT mounting with capacitances from 5 µF to 20 µF and rated voltages between 500 V DC and 900 V DC

We will also introduce the new FA series, a very compact design to achieve extremely high packing densities.

All CeraLink capacitors offer extremely low ESL values of below 3.5 nH and best in class ripple current handling abilities.
The capacitors are designed for an operating temperature range of -40 °C to +150 °C.
