C0G types expand automotive-grade MLCCs

Multi-layer ceramic chip capacitors from TDK now include C0G types, which join the automotive-grade soft-termination and MegaCap Type MLCCs. MegaCap Type MLCCs are available in two designs: the single type and the stacked type.

They join the X5R, X7R and X8R dielectric materials, offering protection against board flexure and solder cracks. The C0G types combine the low relative permittivity of the C0G dielectric with rated capacitance values up to 300nF and enable MLCCs to be used in an even greater range of applications where reliability is required, says the company. Rated voltages range from 50 to 3000V.

The new MLCCs feature high capacitance stability at a high DC bias. Capacitance drift is only 0.3 per cent over a broad temperature range from -55 to +125 degree C, making the Class 1 MLCCs suited for the high-precision resonant circuits for fast and efficient automotive wireless charging and in LLC resonant circuits of on-board chargers for plug-in hybrid and electric vehicles.

All are qualified to AEC-Q200 and can be used in circuits requiring high reliability or as replacements for other types of capacitors.
