Stackpole’s BR Series Bare Element Current Sense Resistors for Lower PCB Temperatures

The BR Series from Stackpole Electronics, Inc. is a thru hole current sense resistor series offering power ratings up to 5 watts with low PCB temperatures. The BR Series elevates the resistive element off of the board for maximum cooling into the ambient air and minimizing the amount of heat that must be dealt with at the board level. This makes the BR Series suited for power management in power supplies, small motors, industrial controls as well as audio applications, robotics, and portable power tools.

The BR Series is available in 1, 3, and 5 watt power ratings, in values from 5 milliohms to 100 milliohms and in tolerances as low as 1%. Pricing varies with size, resistance value, and tolerance, and ranges from $0.16 to $0.38 for the most common values and sizes in full package quantities. Contact Stackpole or one of its franchised distributors for volume pricing. Current lead-times are 8 weeks, with many popular values and sizes available from stock.
