RHS25RE Frequently Asked Questions (FAQs)

  • The thermal resistance of the RHS25RE is not explicitly stated in the datasheet, but according to Ohmite's application notes, the thermal resistance (RθJA) is approximately 10°C/W for the RHS25RE.
  • While the RHS25RE is a ruggedized resistor, it's still important to consider the vibration specifications. Ohmite recommends following the IPC-9592 standard for vibration testing. It's essential to consult with Ohmite's application engineers to determine the suitability of the RHS25RE for your specific high-vibration application.
  • Ohmite recommends using a soldering iron with a temperature of 250°C (482°F) and a solder with a melting point of 180°C (356°F) to 200°C (392°F). It's also important to follow the recommended soldering time and technique to avoid damaging the resistor.
  • The RHS25RE is designed to operate up to 40,000 feet (12,192 meters) above sea level. However, it's essential to consult with Ohmite's application engineers to determine the suitability of the RHS25RE for your specific high-altitude application, as additional testing and validation may be required.
  • The RHS25RE is designed to operate in environments with relative humidity up to 95%. However, it's essential to follow Ohmite's recommended storage and handling procedures to prevent moisture ingress and ensure the resistor's reliability.
