VISHAY INTERTECHNOLOGY Draloric RCS0805 e3 anti-surge thick film resistor in the 0805 case size with a higher power rating of 0.5W, delivers an increased power rating. Device can now be used in place of four standard parallel resistors in the 0805 case size; two parallel devices in the larger 1206 case size; or one resistor in the 1210 case size. This allows designers to save board space in automotive, industrial, telecommunications, and medical applications, while lowering component counts and reducing placement costs. Product excels in applications that are subject to high and repetitive surge pulses. Device features a resistance range from 1Ω to 10MΩ — and 0Ω jumper — with tolerances of ± 0.5 %, ± 1%, and ± 5%, and TCR of ± 100 ppm/K and ± 200 ppm/K. The resistor offers an operating voltage of 150V and an operating temperature range of -55°C to +155°C.
