Ultra HiQ-CBR 0505 Series surface mount multilayer ceramic capacitors (MLCCs)

KEMET’s Ultra HiQ-CBR 0505 Series surface mount multilayer ceramic capacitors (MLCCs) in C0G dielectric feature a robust and exceptionally stable copper electrode dielectric system as well as a square case size that offers excellent low loss performance (ultra high Q). These devices provide extremely low ESR and high self-resonance characteristics, and are well-suited for higher power applications where minimal heating due to I2R losses are a factor. CBR Series capacitors exhibit no change in capacitance with respect to time and voltage, and boast a negligible change in capacitance with reference to ambient temperature. Capacitance change is limited to ±30 ppm/ ºC from −55°C to +125°C.
