RJS500E - Ohmite

RJS500E Frequently Asked Questions (FAQs)

• What is the thermal resistance of the RJS500E?
  The thermal resistance of the RJS500E is typically around 1.5°C/W, but this value can vary depending on the specific application and mounting method.
• Can the RJS500E be used in high-frequency applications?
  While the RJS500E is primarily designed for low-frequency applications, it can be used in high-frequency applications up to 100 kHz with some limitations. However, the inductance and capacitance of the resistor may affect its performance at higher frequencies.
• Is the RJS500E suitable for high-vibration environments?
  The RJS500E is designed to withstand moderate vibration levels, but it may not be suitable for extremely high-vibration environments. Ohmite recommends consulting their application notes or contacting their technical support for specific guidance on vibration testing and requirements.
• Can the RJS500E be used in high-temperature environments?
  The RJS500E has a maximum operating temperature of 150°C, but it can be derated for higher temperatures up to 200°C with reduced power ratings. However, prolonged exposure to high temperatures can affect the resistor's long-term reliability and stability.
• What is the recommended soldering temperature and time for the RJS500E?
  Ohmite recommends soldering the RJS500E at a temperature of 260°C (500°F) for 3-5 seconds, with a maximum temperature of 280°C (536°F) for 1-2 seconds. Exceeding these temperatures or times can damage the resistor or its terminations.
