Vishay Intertechnology Introduces New Series of Pulse−Proof, Sulfur-Resistant Thick Film Resistors

Vishay RCA-IF e3

Vishay Intertechnology released a new series of thick film chip resistors that provides pulse-proof performance and advanced sulfur resistance for automotive, industrial, and medical applications. 

The Vishay Draloric RCA-IF e3 series devices feature excellent anti-surge and pulse characteristics, and for high-sulfur environments offer a sulfur withstand ability in accordance to ASTM B809−95, tested at 90 °C for 1000 hours. The resistors are optimized for applications such as input circuits or MOSFET gate resistors susceptible to pulse loads while operating in a polluted atmosphere.

Vishay RCA-IF e3

The RCA-IF e3 devices are available in seven case sizes ranging from 0402 to 2512 with power ratings from 0.063 W to 1.0 W. The resistors offer a resistance range from 1 Ω to 100 kΩ with tolerances of ± 5 % and ± 10 %, a TCR of ± 200 ppm/K, and a limiting element voltage range of 50 V to 500 V. The lead (Pb)-free devices feature pure tin plating, and are compliant to RoHS directive 2011/65/EU and halogen-free according to the JEDEC JS709A definition.
