Pulse-Proof Sulfur-Resistant Thick-Film Resistors

Vishay Intertechnology, Inc. has 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 degrees C for 1,000 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.

The RCA-IF e3 devices are available in seven case sizes ranging from 0402 to 2512 with power ratings from 0.063W to 1.0W. The resistors offer a resistance range from 1Ω to 100kΩ with tolerances of ±5% and ±10%, a TCR of ± 200 ppm/K, and a limiting element voltage range of 50V to 500V. 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.

An AEC-Q200-qualified version, the RCA-IF AT e3, is also available. Samples of the RCA-IF e3 and RCA-IF AT e3 are available now. Production quantities are also available now, with lead times of eight weeks for larger orders. Pricing for U.S. delivery varies by size and tolerance. For example, pricing for the RCA1206-IF e3 starts at $0.026 per piece.
