Legged ceramic capacitors shun stress

Kyocera AVX has added stand-off legs to surface-mount multi-layer ceramic capacitors to improve bending resilience and suppress thermally-induced weld cracking.

Operation is over -55 to +125°C.

“KGP Series stacked MLCCs are engineered to optimise the performance of high-frequency applications in the industrial, alternative energy and down-hole oil and gas industries,” according to the company.


Both J (pictured) and L style legs are available.


J-lead versions span 1210 (3.5 x 2.5mm footprint) to 2225 (6 x 6.3mm) in five EIA sizes, and there can be one die, or two stacked die (pictured) in the device.

Types with C0G or X7R dielectric are included, with eight voltage ratings from 50V to 1.5kV.

There is also a limited range of X7T dielectric devices, in 1210, 1812 or 2220 footprints, and 250, 450 or 630V voltages).

Capacitance choice is:

  • C0G: 1.8 to 220nF
  • X7R: 33nF to 47μF
  • X7T: 150nF to 4.7μF

The two-stacked devices are all ±20%, while ±10% is an option on single-chip devices.

Circuit uses include dc-dc converters, control, dc blocking and high voltage coupling, the company said.

The capacitors are available from DigiKey or Mouser Electronics

In January, the same company announced high-reliability stacked ceramic capacitors with up to 10 chips per device.
