Planar Non-inductive Power Resistor

The RESI SOTC0227 Series is a high power thick film resistor designed for applications requiring reliable performance under continuous high load and power dissipation conditions. Built using thick film technology on a ceramic substrate, it delivers stable electrical behaviour while handling significant power levels in a compact SOT-227 format. With resistance values from 0.1Ω to 1MΩ and a rated power of up to 300W, the series is well suited to voltage regulation, constant power loads and energy dissipation applications. Its controlled tolerance and temperature coefficient ensure consistent operation across varying conditions. Designed for durability, the SOTC0227 Series provides strong resistance to thermal stress and environmental factors, making it suitable for demanding industrial and high-power electronic systems.
