These VPR7 Bulk Metal^® Foil power current sensing resistors are direct replacements for certain wirewound devices but without the inductive characteristics of wirewounds.

The VPR7 anodized aluminum housing is drilled and countersunk to accept flat head screws for thermal mounting. Because the device is internally Kelvin connected, there is no restriction on the lead lengths as would be the case if this were a two terminal device. Frequently used in YIG oscillator circuits these devices contribute to superior frequency stability.Current Sensing Resistors (Direct Replacement for Certain Wirewounds)
