B20J500E Frequently Asked Questions (FAQs)

  • The thermal resistance of the B20J500E is typically around 10°C/W, but this value can vary depending on the specific application and mounting method.
  • The B20J500E 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 B20J500E 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 more ruggedized component or a resistor with a specialized vibration-resistant design.
  • Yes, the B20J500E is compatible with lead-free soldering processes. Ohmite Mfg Co ensures that their components meet the requirements for lead-free soldering, making it suitable for modern manufacturing processes.
  • Ohmite recommends derating the B20J500E by 1.5% per °C above 25°C to ensure reliable operation. This means that if you're operating the resistor at 50°C, you should derate the power rating by 37.5% (1.5% x 25°C).
