B20J250E - Ohmite

B20J250E Frequently Asked Questions (FAQs)

• What is the thermal resistance of the B20J250E?
  The thermal resistance of the B20J250E is typically around 10°C/W, but this can vary depending on the specific application and mounting method.
• Is the B20J250E suitable for high-frequency applications?
  The B20J250E 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 B20J250E in a high-vibration environment?
  The B20J250E 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 B20J250E RoHS compliant?
  Yes, the B20J250E 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 manufacturer or supplier.
• What is the recommended derating for the B20J250E?
  The recommended derating for the B20J250E is typically 20-30% of the maximum power rating, depending on the ambient temperature and airflow. This ensures reliable operation and prevents overheating.
