Boxed metalized polypropylene film capacitors resist vibrations

February 16, 2017 // By Nick Flaherty
Panasonic Automotive & Industrial Systems Europe is introducing a range of small metalized polypropylene film capacitors with low losses and vibration tolerance 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 metalized polypropylene film with a flame retardant plastic case and come with a  built-in fuse function. Panasonic incubates the molds for a sufficient time to allow the material to sufficiently cure before vacuum treating the molds to remove any excess air bubbles.

“The outer box construction of the ECWFE series capacitors gives the components the capability of withstanding vibrations better than standard dipped type film capacitors," said Mustafa Khan, Product Manager at Panasonic Automotive & Industrial Systems Europe. "The built-in fuse functionality 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.”

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.
