Bare Element Current Sense Resistors


Stackpole Electronics, Inc’s BR Series is an open element radialleaded current sense resistor that raises the element off of the PCB. This allows maximum heat transfer tothe ambient air and lowers PCB temperatures as much as 20ºC compared to similar molded or ceramichoused current sense resistors of similar size.

This all welded design has very low inductance (less than10nH), is flameproof, and offers current handling up to 70 amps.

The BR Series is available in 1, 3, and 5 watt sizes, in tolerances down to 1% with TCR down to ±20PPM,and resistance values as low as 2.5 milliohms. Pricing is size, resistance value, and tolerance dependentand ranges from $0.14 each to $.33 each bulk packaging of 1000 piece quantities.
