Technical Documents

A breakthrough with some of Panasonic’s Automotive, Industrial and Infrastructure Use Films Capacitors, is Panasonic’s Segmented Metallized Fuse Function Technology. Unlike Aluminum Electrolytic Capacitors, where the part opens up upon failure, Film Capacitors short circuit upon failure. Demand has grown within the Electronics industry for a Film Capacitor that would also open upon failure.

Quick Clips: Fuse Function Technology of Panasonic Film Capacitors

EPCOS Film Capacitors are used in a wide range of applications such as output AC filters for power converters, UPS, motor drives, and more. The B3275* Series Film Capacitors have a dielectric of polypropylene (PP) and are optimized for AC voltage performance with high ripple current/frequency handling capability. The B32926C3475M000 Film Capacitor has a capacitance of 4.7 µF and a voltage rating of 630VDC.

Features

The main features of B326 series Film Capacitors may be summarized as follows:

1. Extreme ESL values below 3.5 nH

2. High-operating temperature of -40°C to 150°C

3. Rated voltages of 500, 700, and 900 VDC

4. Capacitance values of 0.25 µF to 20 µF

5. Can be embedded in IGBT modules

Applications

Shunt Power Factor Correction (according to the scope defined in IEC 60831)
Indoor mounting

Frequently Asked Questions

What are some other types of EPCOS Film Capacitors?

EPCOS offers a wide range of Film Capacitors including AC Film Capacitors, Motor Run Metallized Polyester Capacitors (MKT), Metallized Polypropylene Capacitors (MKP/MFP), EMI Suppression Capacitors, Power Capacitors (Film) and more.

What are film capacitors used for?

The metallic film capacitors are widely used in power electronic circuits including DC link circuits, pulse circuits, switching circuits,etc.

How is Film Capacitor different from Electrolytic Capacitor and Ceramic Capacitor?

The first difference which is quite evident between these three capacitors is the type of dielectric used and their construction. While the film capacitors use thin sheets of plastic films, ceramic capacitors have sheets made out of ceramic material as the dielectric.
