Metalised Polypropylene film capacitor

A new range of capacitors are available from Panasonic for harsh industrial applications requiring excellent frequency characteristics and resistance to vibration.

Panasonic Automotive & Industrial Systems Europe is introducing a new range of small size metalised polypropylene film capacitors featuring low loss and excellent frequency characteristics for active filter circuits as well as high frequency and high current circuits. The ECWFE capacitors have been designed with a non-inductive construction using metalised polypropylene film with a flame retardant plastic case and come with a  built-in fuse function. Furthermore, Panasonic incubates the moulds for a sufficient time to allow the material to sufficiently cure before vacuum treating them to remove any excess air bubbles.

Available for a rated voltage of 450VDC with a capacitance range of 0.1µF up to 4.7µF or 630VDC with a capacitance range of 0.1µF up to 2.2µF, the ECWFE series components benefit from a wide operating temperature range from -40°C up to +105°C, a low hum sound noise, and are fully RoHS compliant.

Mustafa Khan, Product Manager at Panasonic Automotive & Industrial Systems Europe remarks: “The durable outer box construction of the ECWFE series capacitors gives the components the capability of withstanding vibrations better than standard dipped type film capacitors. The built-in fuse function allows the ECWFE series to open upon failure rather than short circuit. This makes the parts ideal for power supplies, PFC and other applications where vibrations are a subject of concern.”
