CSR0805FTR820 Equivalent & Substitute Parts

Part Overview

The CSR0805FTR820 is a 0.82 ohm, 1% tolerance, 1/4W chip resistor in 0805 (2012 metric) package manufactured by Stackpole Electronics Inc. This current sense thick film resistor operates across -55°C to 155°C and is designed for precision current measurement applications. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and environmental ratings are maintained across the same package form factor.
