CQL-434/MZ (Polam-Elta) is a fuel-saver type capacitor manufactured by Panasonic. This capacitor utilizes a new type of Thermally Assisted Switchable Dielectric material, MZ, which provides higher capaictance per unit volume and lower loss than existing materials. This capacitor also features an increased capacitance range, high temperature and humidity resistance, and improved stability. It is designed for use in next-generation electric vehicles and power generation systems, as well as in DC/DC converters of LED lighting.
