RC0805FR-07100RL

RC0805FR-07100RL is a 100 Ω ±1% thick-film chip resistor from Yageo in an 0805 (2012 metric) case, documented by Yageo's per-part specification sheet: rated power 0.125 W at 70 °C, temperature coefficient ±100 ppm/°C across −55 °C to +155 °C, maximum continuous working voltage 150 V, overload 300 V and dielectric withstanding voltage 300 V, supplied on 178 mm tape at 5,000 pieces per reel. Working-voltage boundary for this value: the 150 V maximum is the platform ceiling for the case size, not a voltage this 100 Ω part can work at continuously — its 0.125 W rating at 70 °C caps the continuous working voltage at about 3.5 V (the square root of allowable power x resistance), and that cap falls as temperature derates the allowable power; the governing limit is always the lower of the two. The selection point is the termination value on the heavier platform — 100 Ω series and pull-up duty with 0.125 W behind it for positions that see surge or sustained current. Selection advice: the R/K value-field discipline applies here as everywhere in this series: 100R is one hundred ohms, and the 100K code is a different part by three orders of magnitude; the full string in the RFQ is the check.
