New from KOA: WN73H – Wide-Terminal Thin-Film Precision Resistor

KOA is expanding its portfolio of thin-film precision resistors. The WN73H features terminations on the long sides, which enables significantly higher rated power compared to conventionally terminated thin-film types. For instance, the WN73H1J (size 0603) has a rated power of 0.3 watts, and the WN73H2B (size 0612) has a rated power of 1 watt. Derating begins at 85°C (Ambient Temp.) or 125°C (Terminal Part Temp.).

Currently, the WN73H is offered in two sizes, 0306 and 0612. Available TCRs are ±50, ±25, and ±10 ppm/K, and available initial tolerances are ±0.5%, ±0.25%, and ±0.1%. Like all KOA thin-film series, the WN73H exhibits excellent long-term stability, with typical deviations in the 1000-hour endurance test specified at 0.04%. Naturally, the WN73H complies with the requirements of AEC-Q200.
