Stackpole Electronics, Inc. has introduced the RMHT series of AEC-qualified thick film chip resistors for applications that require dependable performance at elevated temperatures. The RMHT series maintains full-rated power up to 105°C, compared with conventional thick film resistors that typically require power derating above 70°C. This capability makes RMHT a strong fit for automotive, aerospace, industrial automation, EV power, motor drives, and under-hood electronic control applications.
The RMHT series is intended for demanding applications where high ambient temperatures, continuous operation, and long service life are important design considerations. Automotive uses include EV powertrain, battery management, and under-hood control modules. The series also supports aerospace and industrial automation systems where reliability under thermal stress is essential. AEC qualification, anti-sulfur protection verified to EIA-977, and 100% automated optical inspection provide added confidence for harsh operating environments.
RMHT resistors are available in 0402, 0603, and 0805 package sizes with resistance values from 1 Ω to 300 kΩ, tolerance options of 0.5%, 1%, and 5%, and 100 ppm/°C or 200 ppm/°C TCR.
As electronic systems increase in power density, RMHT gives engineers a practical option for managing thermal design challenges while supporting efficient board layouts and long-term reliability.
Pricing varies by size, resistance value, and tolerance. Contact Stackpole or an authorized distribution partner for volume pricing and application support.
