AEC-Q200 Soft-Termination C0G MLCCs

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 new 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. Their rated voltages range from 50V to 3000V.

The new MLCCs feature high capacitance stability at a high dc bias. Moreover, the capacitance drift is only 0.3 percent over a broad temperature range from -55 to +125 degrees C, making the new Class 1 MLCCs especially well-suited for the 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 new types are qualified to AEC-Q200. In addition to the expanded range of automotive applications, the new C0G MLCCs are also suitable for use in circuits requiring high reliability or as replacements for other types of capacitors. Mass production and sales of the new components will begin in December 2016.

Main applications are expected to be; Wireless chargers for electric vehicles, LLC resonant circuits of onboard chargers for plug-in hybrid and electric vehicles, and Circuits that require high reliability (time constant circuits, filter circuits, resonant circuits, oscillation circuits, snubber circuits, etc.)
