KEMET Webinar - Long Life and Humidity Grade New Film Box AC Filters

Herunterladen, um offline zu lesen

AC-Filter capacitors are used in power electronic equipment like UPS, Motor Drives, Inverters or Battery Chargers in order to absorb the harmonic current generated in the different power conversion stages.
Film dielectric has the best performance in term of safety thanks to its self-healing property particularly important in AC application.
The new C4AF series, available in 250Vac,310Vac and 400Vac voltage ratings, combines strong performances in current thanks to the low dissipation along with a heavy-duty characterization, being able to withstand 85°C / 85% RH test at rated voltage.
