Pulse-proof thick-film chip resistors are sulphur-resistant
Vishay Intertechnology has released a series of thick film chip resistors that provides pulse-proof performance and advanced sulphur 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-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 power ratings from 0.063 to 1.0W. The resistors offer a resistance range from 1Ω to 100kΩ with tolerances of ±5% and ±10%, a TCR of ±200ppm/K, and a limiting element voltage range of 50 to 500V. The 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.
