B20J100KE - Ohmite

B20J100KE Frequently Asked Questions (FAQs)

• What is the thermal resistance of the B20J100KE?
  The thermal resistance of the B20J100KE is typically around 10°C/W, but it can vary depending on the specific application and mounting method.
• Is the B20J100KE suitable for high-frequency applications?
  The B20J100KE 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.
• Can I use the B20J100KE in a high-vibration environment?
  The B20J100KE 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.
• Is the B20J100KE compatible with lead-free soldering?
  Yes, the B20J100KE is compatible with lead-free soldering. Ohmite Mfg Co uses a lead-free termination material that meets the requirements of the RoHS directive.
• What is the recommended derating for the B20J100KE?
  The recommended derating for the B20J100KE 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.
