High Voltage C0G MLCCs (Commercial & Auto Grade) KEMET High Voltage Surface Mount MLCCs in C0G dielectric are temperature compensating and suited for resonant circuit applications or where Q and stability of capacitance characteristics are required. C0G exhibits no change in capacitance with respect to voltage and time and boasts a negligible change in capacitance with reference to ambient temperature. Capacitance change is limited to ±30ppm/°C from -55°C to +125°C, and these devices offer low ESR at high frequencies and fine conventional use as filters or snubbers in switching power supplies, lighting ballasts, etc. Commercial-grade and automotive-grade devices that meet AEC-Q200 qualifications are available. These capacitors from KEMET are lead (PB)-free, RoHS, and REACH compliant without exemption.
