B12J20KE - Ohmite

B12J20KE Frequently Asked Questions (FAQs)

• What is the thermal resistance of the B12J20KE?
  The thermal resistance of the B12J20KE is typically around 10°C/W, but this can vary depending on the specific application and mounting method.
• Is the B12J20KE suitable for high-frequency applications?
  The B12J20KE 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 B12J20KE be used in high-vibration environments?
  The B12J20KE is designed to withstand moderate vibration, but it's not suitable for extreme vibration environments. If your application involves high vibration, you may need to consider additional mounting or potting to ensure reliability.
• Is the B12J20KE compatible with lead-free soldering?
  Yes, the B12J20KE is compatible with lead-free soldering processes, but it's essential to follow the recommended soldering profile to avoid damaging the component.
• What is the recommended derating curve for the B12J20KE?
  The recommended derating curve for the B12J20KE is typically 1.5% per °C above 25°C. This means that for every degree above 25°C, the resistor's power rating should be reduced by 1.5% to ensure reliable operation.
