KOA Speer Introduces New Anti-Sulfur RK73H-RT Thick Film Chip Resistor

Bradford, PA -- KOA Speer Electronics introduces the latest in precision thick film chip resistors, the anti-sulfur RK73H-RT. Made with a sulfur-proof electrode material, the RK73H-RT resistor features precision tolerances of 0.5% and 1.0% and a resistance range of 10Ω ~ 10MΩ.

KOA Speer's RK73H-RT chip resistor has a power rating from 1/16W up to 1W and TCR values of ±100 and ±200ppm/°C. With an operating temperature of -55°C to 155°C, the RK73H-RT uses a thick metal glaze film to provide excellent heat resistance and weather resistance, making it a high stability and high reliability triple layer structure.

The RK73H-RT chip resistor is available in sizes ranging from 0402 up to 2512, and is ideal for industrial, automotive, transportation, telecommunication and consumer markets, in applications such as power supplies, factory automation, car electronics, oil-rich environments and outdoor environments such as welding, mining, agriculture and winery.

The RK73-RT series meets ASTM-B-809 Flowers of Sulfur testing and is AEC-Q200 qualified. Lead time is 10 weeks, please contact KOA Speer for more information.
