RST Electric presents TO220 Thick Film Power Resistor – a compact, high-performance resistor designed for power electronics requiring efficient thermal management and easy assembly. Housed in a standard TO220 plastic package with a metal mounting tab, this TO220 Power Resistor delivers 35W (PRT35) or 50W (PRT50) at 25°C case temperature when properly heatsink mounted. With a wide resistance range from 0.1Ω to 1MΩ and tolerances as tight as ±0.5%, it is ideal for switching power supplies, snubber circuits, power amplifiers, and voltage regulation applications. The molded plastic case provides high insulation resistance (>10GΩ) and withstands 1800VAC dielectric strength, while the non-inductive thick film construction ensures stable performance in high-frequency circuits.

RST Electric introduces TO247 Thick Film Power Resistor – a high-power, surface-mountable resistor designed for demanding power electronics requiring superior thermal management. Housed in a standard TO247 plastic package with an integral mounting tab, this TO247 Power Resistor delivers 100W at 25°C case temperature when properly heatsink mounted, making it ideal for high-power switching supplies, pulse loading circuits, power amplifiers, and snubber networks. With a wide resistance range from 0.2Ω to 1MΩ, tolerances as tight as ±1%, and a maximum working voltage of 700V, it offers exceptional versatility for industrial, automotive, and renewable energy applications. The molded plastic case provides high insulation resistance (>10GΩ) and withstands 1800VAC dielectric strength, while the non-inductive thick film construction ensures stable performance in high-frequency circuits.
