The thermal resistance of the WLCR100FE is typically around 10°C/W, but this can vary depending on the specific application and mounting method.
The WLCR100FE is a wirewound resistor, which can exhibit significant inductance at high frequencies. It's not recommended for high-frequency applications above 100 kHz. For high-frequency applications, consider using a thin-film or metal-film resistor instead.
The WLCR100FE is designed to withstand moderate vibration, but it's not recommended for extreme vibration environments. If you need a resistor for a high-vibration application, consider using a resistor with a more robust construction, such as a ceramic or metal-cased resistor.
Yes, the WLCR100FE is compatible with lead-free soldering. Ohmite Mfg Co uses a lead-free termination material that meets the requirements of the RoHS directive.
The power rating of the WLCR100FE decreases as the temperature increases. At 25°C, the power rating is 100W, but at 50°C, it's derated to 75W, and at 70°C, it's derated to 50W. Consult the datasheet for the full derating curve.
