45F1K5E Frequently Asked Questions (FAQs)

  • The thermal resistance of the 45F1K5E is typically around 10°C/W, but this value can vary depending on the specific application and mounting method.
  • While the 45F1K5E 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.
  • The 45F1K5E 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.
  • Yes, the 45F1K5E is compatible with lead-free soldering processes. Ohmite Mfg Co uses lead-free materials and manufacturing processes to ensure compliance with RoHS and other environmental regulations.
  • As a general rule, it's recommended to derate the 45F1K5E by 1% for every 1°C above 50°C. This means that if you're operating the resistor at 100°C, you should derate its power rating by 50% to ensure reliable operation.
