C0G-type MLCCs Are Rated to 300 nF

30 November 2016

Automotive-grade soft-termination and MEGACAP-type MLCCs. Source: TDK Automotive-grade soft-termination and MEGACAP-type MLCCs. Source: TDK TDK Corporation has expanded its lineup of automotive-grade soft-termination and MEGACAP-type MLCCs with new C0G types. Until now, these robust MLCC designs, which offer effective protection against board flexure and solder cracks, have been available with X5R, X7R and X8R dielectric materials.

The capacitors combine the low relative permittivity of the C0G dielectric with rated capacitance values up to 300 nF, and they enable MLCCs to be used in an even greater range of applications requiring reliability. Their rated voltages range from 50 V to 3,000 V.

The MLCCs feature high capacitance stability at a high DC bias. Moreover the capacitance drift is only 0.3% over a broad temperature range from –55° C to +125° C. This suits the Class 1 MLCCs for high-precision resonant circuits for fast and efficient automotive wireless charging, and in LLC resonant circuits of onboard chargers for plug-in hybrid and electric vehicles. The capacitors are qualified to AEC-Q200.

In addition to the expanded range of automotive applications, the C0G MLCCs are suited for circuits requiring high reliability or as replacements for other types of capacitors. Mass production of the capacitors will begin in December.
