Stackpole’s RMCA Automotive Grade Chip Resistors Deliver Higher Power Density for Space-Constrained Designs
29 July 2026 
Stackpole Electronics has announced it has expanded design flexibility for automotive and other high-reliability electronics with its RMCA Series automotive grade chip resistors, now available with high power (-HP) and ultra-high power (-UP) options.
The company says the RMCA Series is engineered for applications that require long service life, stable performance, and efficient use of PCB space, helping design engineers increase power handling without moving to larger resistor footprints or more costly established-reliability alternatives.
For engineers working on automotive, industrial, transportation, and power management designs, the RMCA Series addresses a common trade-off: higher reliability and tighter performance requirements often reduce available power ratings. Stackpole’s -HP and -UP options give designers additional margin for current sensing, voltage division, biasing, and general-purpose circuit protection in layouts where board space is limited and thermal performance is critical.
Automotive grade materials, design, and manufacturing make the RMCA Series well suited for products with demanding qualification expectations, extended warranty periods, or mission-critical functionality. By combining automotive grade reliability with higher power density, the RMCA Series can help engineering teams reduce component count, conserve PCB area, and improve design robustness in compact electronic assemblies.
