Riedon S1-0R01J8 Equivalent & Substitute Parts

Part Overview

The Riedon S1-0R01J8 is a 10 mOhms ±5% wirewound chip resistor rated at 0.5W (1/2W) in a 1913 J-Lead package. This current sense resistor is designed for precision measurement applications requiring low resistance values with flame-proof, moisture-resistant, and pulse-withstanding characteristics. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are maintained while offering improved tolerance specifications or enhanced availability.
