30J150E - Ohmite

30J150E Frequently Asked Questions (FAQs)

• What is the thermal resistance of the 30J150E?
  The thermal resistance of the 30J150E is typically around 10°C/W, but this can vary depending on the specific application and mounting method.
• Is the 30J150E suitable for high-frequency applications?
  The 30J150E is a wirewound resistor, which can exhibit significant inductance at high frequencies. It may not be the best choice for high-frequency applications, but it can still be used up to a few hundred kHz with proper design considerations.
• Can the 30J150E be used in high-vibration environments?
  The 30J150E is designed to withstand moderate vibration, but it may not be suitable for extremely high-vibration environments. Ohmite recommends following their vibration testing guidelines to ensure the resistor meets the specific application requirements.
• What is the recommended derating curve for the 30J150E?
  Ohmite recommends derating the 30J150E by 1.5% per degree Celsius above 25°C to ensure reliable operation. This means that at 50°C, the resistor should be derated to 85% of its rated power.
• Is the 30J150E compatible with lead-free soldering processes?
  Yes, the 30J150E is compatible with lead-free soldering processes, but Ohmite recommends following their recommended soldering profile to ensure reliable assembly.
