KOA Speer Electronics now offers the 0402 1E size in the RN73H line of ultra-precision chip resistors. The thin-film metal chip resistors feature heat resistance up to 155°C (311°F) and high-precision tolerance of ±0.1%. Moisture resistance improves through the use of a protective layer-over resistive film construction. The RN73H1E chip resistor also features a power rating of 0.063 W, TCR values of ±10 ~ ±50 ppm/°C, and a resistance range of 10 ~ 300 kΩ. Additionally, the RN73H1E is available with lead-free terminations to meet EU RoHS requirements. Used primarily as precision resistors impervious to humidity and temperature, the RN73H1E chip resistors are suitable for off-highway applications where high temperature and high humidity are design considerations.
