41FR20E - Ohmite

41FR20E Frequently Asked Questions (FAQs)

• What is the thermal resistance of the 41FR20E?
  The thermal resistance of the 41FR20E is typically around 10°C/W, but this value can vary depending on the specific application and mounting method.
• Is the 41FR20E suitable for high-frequency applications?
  While the 41FR20E is a wirewound resistor, it's not ideal for high-frequency applications (>1 MHz) due to its inductive nature. For high-frequency applications, consider using a thin-film or metal-film resistor instead.
• Can I use the 41FR20E in a high-vibration environment?
  The 41FR20E is designed to withstand moderate vibration, but it's not suitable 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.
• Is the 41FR20E compatible with lead-free soldering?
  Yes, the 41FR20E is compatible with lead-free soldering processes, but it's essential to follow the recommended soldering profile and temperature guidelines to ensure reliable assembly.
• What is the recommended derating curve for the 41FR20E?
  The recommended derating curve for the 41FR20E is typically around 1.5% per °C above 25°C. This means that for every 1°C increase in temperature above 25°C, the resistor's power rating should be derated by 1.5% to ensure reliable operation.
