RC0402JR-070RL

RC0402JR-070RL is a 0 Ω jumper chip resistor from Yageo in a 0402 (1005 metric) case — Yageo's per-part specification sheet titles it a standard jumper chip resistor with nominal resistance 0 mΩ, on the RC0402 frame (0.063 W at 70 °C, −55 °C to +155 °C, maximum continuous 50 V / overload 100 V / dielectric 100 V), supplied on 178 mm tape at 10,000 pieces per reel. A jumper is not specified like a resistor: the governing figures are the resistance ceiling and the current — Yageo's series documentation puts the RC jumper class below 50 mΩ, with the RC0402 jumper rated 1.0 A and a 2.0 A maximum. The selection point is a configuration link that a pick-and-place line can fit: option strapping, test-point bridging and late BOM changes without a board spin. Selection advice: do not read the J in the code as a ±5% resistor tolerance — there is no resistance value to tolerate; if your design needs a real 0 Ω with a current budget above the series figures, say so in the RFQ.
