The thermal resistance of the 20J47RE is typically around 10°C/W, but this can vary depending on the specific application and mounting method.
The 20J47RE is a wirewound resistor, which can exhibit inductive effects 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 20J47RE 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 20J47RE is RoHS compliant, meaning it meets the European Union's Restriction of Hazardous Substances directive. However, it's always a good idea to verify compliance with the specific regulations applicable to your project.
The recommended derating for the 20J47RE is 50% of the maximum power rating at 70°C. This means that if the resistor is rated for 20W, you should limit the power to 10W at 70°C to ensure reliable operation.
