Polypropylene film capacitors incubates the moulds to protect
Polypropylene film capacitors incubates the moulds to protect: Small, metalised polypropylene film capacitors feature low loss and frequency characteristics for active filter circuits as well as high frequency and high current circuits, says Panasonic.
The ECWFE capacitors have been designed with a non-inductive construction using metalised polypropylene film with a flame-retardant plastic case. They have a built-in fuse function and incubate the moulds for a sufficient time to allow the material to sufficiently cure before vacuum treating the moulds to remove any excess air bubbles.
Available for a rated voltage of 450V DC with a capacitance range of 0.1 to 4.7microF or 630V DC with a capacitance range of 0.1 to 2.2microF, the ECWFE components benefit from a wide operating temperature range from -40 to + 105 degree C, a low hum sound noise, and are RoHS compliant.
The durable outer box construction 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 them suitable for power supplies and power factor correction, and other applications where vibrations are a concern.
