Low cost current sense resistors handle 32 A

The BR series radial leaded thru-hole current sense resistors come in power ratings of 1, 3, or 5 W, de-rated from 85°C, with values from 0.005 – 0.100 Ω. The devices simple non-inductive construction provides for maximum ambient air cooling on the PCB.

The resistors tolerance is 1, 2, or 5%, with a ±200 ppm/°C maximum TCR. An example part number BR3FB10L0 is a 3 SaveW, 0.010 Ω, 1% tolerance device. This part sells for $0.62 ea/100 and is available now.
