I Cylindrical Fixed Resistor APPLICATION INFORMATION

When the resistor dissipates power, a temperature rise above the ambient temperature occurs, dependent on the thermal resistance of the assembled resistor together with the printed circuit board. The rated dissipation applies only if the permitted film temperature is not exceeded. These resistors do not feature a limited lifetime when operated within the permissible limits. However, resistance value drift increasing over operating time may result in exceeding a limit acceptable to the specific application, thereby establishing a functional lifetime.

II Cylindrical Fixed Resistor Applications

- Water heaters
- Welding equipment
- Power supplies for plasma cutters
- Gas and diesel powered engine controls
- Electric meters
- Utility meters
- Communications equipment
- Power/network/phone distribution equipment
- Lighting
- Thermostats and HVAC controls
