RC0402FR-07100RL

RC0402FR-07100RL is a 100 Ω ±1% thick-film chip resistor from Yageo in a 0402 (1005 metric) case, documented by Yageo's per-part specification sheet: temperature coefficient ±100 ppm/°C across −55 °C to +155 °C, maximum continuous working voltage 50 V and overload voltage 100 V, on the RC0402 platform rated 0.063 W at 70 °C, supplied on tape and reel. Working-voltage boundary for this value: the 50 V maximum is the platform ceiling for the case size, not a voltage this 100 Ω part can work at continuously — its 0.063 W rating at 70 °C caps the continuous working voltage at about 2.5 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 100 Ω standard value for termination, pull-up duty on fast lines and RC filtering in the smallest mainstream case. Selection advice: read the string as written — 100R in this series is one hundred ohms, while the visually adjacent 100K code (RC0402FR-07100KL, also listed here) is one hundred kilohms, a thousand times more; value-field mix-ups between R and K codes are the most common chip-resistor ordering error, and the full code in your RFQ is what protects against it.
