RC0402FR-07330RL

RC0402FR-07330RL is a 330 Ω ±1% thick-film chip resistor from Yageo in a 0402 (1005 metric) case, documented by Yageo's per-part specification sheet: rated power 0.063 W at 70 °C, temperature coefficient ±100 ppm/°C across −55 °C to +155 °C, maximum continuous working voltage 50 V, overload 100 V and dielectric withstanding voltage 100 V, supplied on 178 mm tape at 10,000 pieces per reel. Working-voltage boundary for this value: the 50 V maximum is the platform ceiling for the case size, not a voltage this 330 Ω part can work at continuously — its 0.063 W rating at 70 °C caps the continuous working voltage at about 4.6 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 330 Ω standard value — LED current setting from 5 V rails, gate resistors and RC filter positions — at platform accuracy in the small case. Selection advice: for LED duty the resistor's dissipation is set by the rail minus the diode drop, not by the nominal current alone; run the platform's 0.063 W against the worst-case rail before choosing the value.
