41F4R0E Frequently Asked Questions (FAQs)

  • The thermal resistance of the 41F4R0E is not explicitly stated in the datasheet, but according to Ohmite's general specifications for their 41F series, the thermal resistance is typically around 10-15°C/W.
  • While the 41F4R0E is a wirewound resistor, it's not specifically designed for high-frequency applications. Ohmite recommends their FFR series for high-frequency use cases. However, the 41F4R0E can still be used in lower-frequency applications up to a few hundred kHz.
  • The 41F4R0E is a wirewound resistor with a ceramic core, which provides some degree of vibration resistance. However, it's essential to consult Ohmite's vibration testing specifications and ensure the resistor is properly secured to withstand the expected vibration levels in your application.
  • Yes, the 41F4R0E is RoHS compliant, meaning it meets the European Union's Restriction of Hazardous Substances directive. Ohmite ensures that their products comply with this regulation.
  • Ohmite recommends a soldering temperature of 260°C (500°F) for 3-5 seconds. It's essential to follow proper soldering techniques and temperature control to avoid damaging the resistor.
