2% Metal Oxide Film Resistor 1W 2W 3W, Ultra Small Flameproof Power Resistor
- Ultra high thermal conductivity material, excellent power dissipation in small volume.
- Flameproof painting, resistance to heat & solvents.
- Annual shift is low for the strengthened metal oxide film.
The RSU series is an ultra small metal oxide film power resistor designed for electronic circuits where compact component dimensions and defined power dissipation are required. Its high thermal conductivity material supports effective power dissipation within a small volume, while the flameproof coating provides resistance to heat and solvents.
The series covers 1W, 2W, and 3W rated power options and is configured here with 1% resistance tolerance for B2B electronic component applications. Its compact construction makes the RSU series suitable for circuit designs where PCB space, rated power, and electrical insulation performance are important selection factors.
The strengthened metal oxide film is designed with low annual resistance shift, providing a parameter-based option for electronic circuits where resistance characteristics need to be maintained over service conditions.
