KEMET Polypropylene Capacitor ±5% 100 nF 400 V dc 250 V ac Radial Terminal R76MI31004030J

The KEMET R76MI31004030J is a high-performance polypropylene capacitor designed for reliable operation in demanding electronic circuits requiring a 100 nF capacitance with a tolerance of ±5%. It supports a rated DC voltage of 400 V and an AC voltage rating of 250 V, suitable for both power electronics and signal integrity applications.

This capacitor uses double metallized polypropylene film technology within a radial terminal package that allows straightforward PCB integration. Its encapsulation in a UL 94V-0 compliant, solvent-resistant plastic case offers enhanced safety and durability against environmental factors.

With a lead pitch of 15 mm and a lead length of 30 mm, it ensures proper mechanical stability for most circuit designs. The capacitor can operate efficiently across a wide temperature range from -55°C up to 105°C, making it ideal for automotive-grade applications conforming to AEC-Q200 standards.

Typical applications for the R76 series capacitors include suppression in switched mode power supplies, snubber circuits, silicon controlled rectifier commutation circuits, and deflection circuits in television sets. The exceptionally low dissipation factor of 0.0003% and an ESR of 25 mΩ contribute to the device’s excellent performance in high-frequency environments.

KEMET’s R76 series capacitors also feature self-healing properties, enhancing their reliability and lifespan in demanding electrical conditions. The capacitor range spans capacitances from 100 pF to 15 µF with voltage spans from 250 to 2000 V dc, accommodating a broad spectrum of design requirements.

Dimensionally, this model measures 18 mm in length, 13.5 mm in height, and 7.5 mm in width, providing a compact footprint suitable for space-constrained industrial, automotive, and commercial electronic assemblies.
