Draloric RCA-IF e3 series

Vishay Intertechnology has released the Draloric RCA-IF e3 series, a family of thick film chip resistors that provides pulse-proof performance and advanced sulphur resistance for automotive, industrial and medical applications.

The Draloric RCA-IF e3 series devices feature anti-surge and pulse characteristics, and for high-sulphur environments offer a sulphur withstand ability in accordance to ASTM B809?95, tested at 90°C for 1,000 hours. The resistors are optimised 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 0.063W to 1W power ratings. The resistors offer a resistance range from 1Ω to 100kΩ with tolerances of ±5per cent and ±10per cent, a TCR of ±200ppm/K, and a limiting element voltage range of 50V to 500V. The lead-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 e and, RCA-IF AT e3 are available now. Production quantities are also available now, with lead times of eight weeks for larger orders.
