The HQ Series MLC with the P90 dielectric material features an ultra-low equivalent series resistance (ESR) and dissipation factor at high frequencies. The HQ Series capacitor with P90 dielectric is now available in E case sizes.

The HQ Series power capacitors are designed for 300V to 7,200V applications and feature a dielectric strength of 120% of rated WVDC. The devices can handle the high power and high voltage levels of RF power amplifiers, inductive heating and high magnetic field environments (MRI coils).

AVX’s HQ Series devices provide medical and industrial electronics experts with the high power and high voltage characteristics necessary for optimal performance. The HQ Series feature capacitance values from 5,100pF down to 1pF. The HQ Series power capacitors feature a temperature coefficient of 0±30ppm/ºC or 90 ± 30ppm/ºC over the operating temperature range of –55ºC to +125ºC.
