Electronic Concepts - Model 3MP Series -Metallized Polypropylene Capacitor for High RMS Currents and AC Filtering

The 3MP Series Metallized Polypropylene Capacitor is designed for contemporary high-energy AC filtering applications, capable of handling high RMS currents. It features a robust integrated flange allowing versatile mounting positions and offers both male and female terminal options. A unique attribute is its capacity to include a thermal sensing device at the capacitor's hot spot. This setup includes a normally open or closed thermal cut-out (TCO) potted at the geometric center of the device, designed to trigger user-defined circuits at critical temperatures. The capacitor can also accommodate other sensing technologies as per customer specifications. It can withstand a DC potential of 1.5 times the rated voltage for one minute without damage or breakdown, discharged through a minimum resistance of 1 OHM per volt minimum. The polypropylene material used ensures a dissipation factor of less than 2.1 x 10^-4 across the operating temperature range of -55°C to +105°C, and frequencies up to 1MHz.

Designed to Handle High RMS Currents

For today’s high energy AC filtering, the 3MP series has a robust integrated flange for versatile mounting positions along with male and female terminal options. It’s most unique feature is that it has been outfitted to accept a thermal sensing device located at the capacitor hot spot. A normally open or closed thermal cut-out (TCO) is potted in the geometric center of the device. As the capacitor reaches critical temperatures the TCO opens and a user defined circuit will trigger the appropriate action. The capacitor can also accept other sensing technology per customer specification.
