Vishay Intertechnology has introduced a new series of thick-film chip resistors for automotive and industrial applications which offer a combination of excellent resistance to atmospheric sulphur with high power and pulse- load performance.
The RCA-HP e3 series of resistors has a special robust construction which provides an ability to withstand concentrations of sulphur in saturated vapour form in accordance with the ASTM B809-95 standard. Sulphur resistance is verified through accelerated testing at 90°C for 1,000 hours.
In addition, the resistors can handle high and repetitive pulses, and support power dissipation of as much as 1.5W.
The RCA-HP e3 series resistors are available in eight case sizes ranging from 0402 to 2512. The devices offer resistance values ranging from 1Ω to 1MΩ, with tolerances of ±1% and ±5%. The devices are specified with a thermal coefficient of resistance of ±100ppm/K or ±200ppm/K.
All the resistors feature double-sided printed resistor elements with a protective coating, apart from the RCA0402-HP e3 which is single-sided. The devices have pure tin plating, which provides compatibility with lead- free and lead-containing soldering processes.
