Anti-surge chip resistors provide up to 0.4W power rating

Devices in Vishay's Draloric RCS e3 series offer better pulse load performance and ESD surge characteristics when compared to standard chip resistors.

Vishay Intertechnology has rolled out a new series of anti-surge, high-power thick film chip resistors optimised for automotive and industrial applications.

For applications subject to high and repetitive surge pulses, devices in the AEC-Q200-qualified Vishay Draloric RCS e3 series offer superior pulse load performance and ESD surge characteristics when compared to standard chip resistors. In addition, the devices provide higher power ratings up to 0.4W.

RCS e3 series resistors are available in three compact case sizes to save space on densely packed PCBs — 0402, 0603, and 0805. With its specified power of 0.25W, the RCS0603 e3 resistor covers the power ratings of standard 0603, 0805, and 1206 resistors, allowing designers to standardise components and take advantage of the lower costs of smaller components.

The devices offer a resistance range from 1Ω to 10MΩ with tolerances of ±0.5%, ±1%, and ±5%; TCR of ±100ppm/K and ±200ppm/K; and an operating voltage range from 50V to 150V. The resistors operate over a temperature range of -55°C to 155°C, and are RoHS-compliant and halogen-free.
