Automotive-grade soft-termination and MEGACAP Type MLCCs combine the low relative permittivity of the C0G dielectric with rated capacitance values up to 300 nF and enable MLCCs to be used where reliability is required. Their rated voltages range from 50 V to 3 kV.
Developed by TDK Corp., the new MLCCs feature high capacitance stability at a high dc bias. Moreover, the capacitance drift is only 0.3% over a temperature range from -55 to +125 ºC, 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 also include circuits that require high reliability (time constant circuits, filter circuits, resonant circuits, oscillation circuits, snubber circuits, etc.). The components display a high capacitance stability at a high dc bias and protect against board flexure and solder cracks. They are also qualified to AEC-Q200.
