Murata Manufacturing Co., Ltd. has commercialized the KCM series of metal-terminal multilayer ceramic capacitors for automobiles with temperature-compensated U2J characteristics and the KRM series of metal-terminal multilayer ceramic capacitors for general use. Our main goal is to use it for IGBT buffer circuits in automotive equipment and industrial equipment. The product started mass production in May 2020.
Product Brief
A snubber circuit is a circuit that prevents the generation of spiked high voltages during the switching process and protects power supply equipment such as IGBTs that use switching devices. The capacitors that make up this snubber circuit are used to absorb the surge voltage generated by the inductance of transformers, wiring, etc., and protect the switching elements and peripheral parts.
In automotive equipment and industrial equipment, the miniaturization of built-in modules due to high functionality and the increasing use of SiC with excellent heat resistance have led to the miniaturization and high temperature of electronic components used. Compatibility requirements.
This product is a metal-terminal multilayer ceramic capacitor. Compared with high-dielectric constant ceramic materials, it uses temperature-compensated ceramic materials with low loss, small self-heating, and small changes in electrostatic capacitance. The miniaturization and high-temperature compatibility of the parts of the buffer circuit through which a large current flows.
In addition, we have added a 1250V rated product that is not in the C0G feature to the product lineup to meet a wider range of needs.
