Vishay has announced that it has enhanced the Vishay Draloric RCS0805 e3 anti-surge thick film resistor in the 0805 case size with a higher power rating of 0.5W.

With its increased power rating, the RCS0805 e3 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. For applications subject to high and repetitive surge pulses, the resistor also offers superior pulse load performance and ESD surge characteristics when compared to standard chip resistors.

AEC-Q200 qualified, the RCS0805 e3 features a resistance range from 1Ω to 10MΩ — and 0Ω jumper — with tolerances of ±0.5%, ±1%, and ±5%, and TCR of ±100ppm/K and ±200ppm/K. The resistor offers an operating voltage of 150V and an operating temperature range of -55°C to +155°C. RoHS-compliant and halogen-free, the device is suitable for processing on automatic assembly systems and for wave, reflow, or vapour phase soldering per IEC 61760-1.

Samples of the enhanced RCS0805 e3 are available now, with lead times of 12 weeks.
