New capacitors benefit from low loss and excellent frequency characteristics

Panasonic Automotive and Industrial Systems Europe has a new range of small size metalized 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 metalized polypropylene film with a flame retardant plastic case and come with a built-in fuse function. Furthermore the company 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. 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 series components benefit from a wide operating temperature range from -40C up to +105C, a low hum sound noise, and are fully RoHS compliant. Mustafa Khan, product manager at Panasonic Automotive and 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 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.”
