Reliable High-Performance Resistors

- Advertisement -

The resistors enhance reliability and performance without high costs, suitable for automotive, medical, and aerospace applications, and fully compliant with stringent standards.


A wide range of electronic products across multiple market segments demand highly reliable components. Automotive grade resistors deliver this increased reliability and enhanced performance without the steep costs and restricted availability associated with military-spec components that adhere to established reliability standards. Moreover, in applications requiring specific pulse withstand capabilities, such options are particularly scarce.

The RPCA series from Stackpole, which is AEC-Q200 qualified, offers superior pulse handling capabilities due to its use of proprietary materials, design, and manufacturing processes. Manufactured on dedicated lines with rigorous material and process controls essential for an automotive grade chip resistor, this series also includes 100% automated optical inspection (AOI). These features grant the RPCA exceptional test outcomes on all AEC-Q200 tests and significantly reduce the expected failure rate by a factor of ten or more. Additionally, the RPCA demonstrates excellent anti-sulfur attributes, successfully passing the ANSI/EIA977 sulfur test with minimal resistance shift at 105C.

Suitable for use in automotive electronics, medical devices, military and aerospace applications not requiring established reliability, as well as in instrumentation and metering, the RPCA stands out as a robust solution.

Some of the key features of the RPCA series include:

  • Anti-sulfur
  • Excellent pulse withstanding performance
  • Broad resistance range
  • Higher anti-surge performance compared with RMCF Series
  • Standard power RPCA, 5% and wider tolerances, are untrimmed
  • RoHS compliant, REACH compliant, and halogen free
  • AEC-Q200 qualified

The pricing of the RPCA varies based on size, resistance value, power rating, and tolerance. 

Stackpole Electronics Inc. is a manufacturer of resistors. Headquartered in Raleigh, N.C., the company started manufacturing in 1928 as part of Stackpole Carbon Company in St. Mary’s, Pennsylvania. Now part of the Akahane Stackpole Manufacturing Group, Stackpole has facilities in Japan, Taiwan, China, the US, and Mexico.
