GRA : Polypropylene Capacitor: 450Vdc - 1100Vdc

Product description

The GRA range of capacitors has been designed to offer designers of dc filtering applications an alternative to electrolytic capacitors. Manufactured from metallised polypropylene film, the component offers a very high volumetric efficiency along with very low losses and high current handling capability.

The capacitors are housed in a choice of low profile cases, manufactured from material which meets the flammability requirements of UL 94-V0 and flanged for easy fixing.
