Overview
KEMET’s COG dielectric features a 125°C maximum operating temperature and is considered “stable.” It is suited for resonant circuit applications or those where Q and stability of capacitance characteristics are required.
Benefits
The COG dielectric exhibits no change in capacitance with respect to time and voltage and boasts a negligible change in capacitance with reference to ambient temperature. It also offers a wide operating temperature range, is lead (Pb)-free, RoHS, and REACH compliant, and has a high thermal stability.
Applications
Typical applications include critical timing, tuning, circuits requiring low loss, circuits with pulse, high current, decoupling, bypass, filtering, transient voltage suppression, blocking, and energy storage.
Electrical Parameters/Characteristics
The COG dielectric has a capacitance change with reference to +25°C and 0 VDC applied (TCC) of +30 ppm/°C, an aging rate of 0%, and a dielectric withstanding voltage (DWV) of 250% of rated voltage.
