25J7K5E - Ohmite

25J7K5E Frequently Asked Questions (FAQs)

• What is the thermal resistance of the 25J7K5E?
  The thermal resistance of the 25J7K5E is typically around 10°C/W, but this value can vary depending on the specific application and mounting method.
• Is the 25J7K5E suitable for high-frequency applications?
  The 25J7K5E 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 25J7K5E in a high-vibration environment?
  The 25J7K5E 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 25J7K5E compatible with lead-free soldering?
  Yes, the 25J7K5E is compatible with lead-free soldering. Ohmite Mfg Co uses a lead-free termination material that meets the requirements of the RoHS directive.
• What is the recommended derating for the 25J7K5E in high-temperature applications?
  Ohmite recommends derating the 25J7K5E 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.
