45F1K0E - Ohmite

45F1K0E Frequently Asked Questions (FAQs)

• What is the thermal resistance of the 45F1K0E?
  The thermal resistance of the 45F1K0E is approximately 10°C/W, which means it can dissipate 45W of power while maintaining a temperature rise of 10°C above ambient.
• Is the 45F1K0E suitable for high-frequency applications?
  While the 45F1K0E is a wirewound resistor, it's not ideal for high-frequency applications (>1MHz) due to its inductive nature. For high-frequency applications, consider using a thin-film or thick-film resistor instead.
• Can I use the 45F1K0E in a high-vibration environment?
  The 45F1K0E is designed to withstand moderate vibration levels, 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 45F1K0E RoHS and REACH compliant?
  Yes, the 45F1K0E is RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) compliant, making it suitable for use in most modern electronic devices.
• What is the recommended derating curve for the 45F1K0E?
  Ohmite recommends derating the 45F1K0E by 1.5% per °C above 25°C to ensure reliable operation. This means that for every 1°C increase in temperature above 25°C, the resistor's power rating should be reduced by 1.5%.
