B20J12K5E Frequently Asked Questions (FAQs)

  • The recommended soldering temperature is 260°C (500°F) with a maximum soldering time of 3 seconds. It's essential to follow the soldering profile recommended by Ohmite to ensure the resistor's reliability and performance.
  • While the B20J12K5E is a high-power resistor, it's not specifically designed for high-frequency applications. Ohmite recommends using their high-frequency resistor series, such as the HFC series, for applications above 100 kHz.
  • The B20J12K5E is designed to withstand moderate vibration levels. However, for high-vibration environments, Ohmite recommends using their vibration-resistant resistor series, such as the VRS series, which are specifically designed to withstand extreme vibration and shock.
  • The thermal resistance of the B20J12K5E is not explicitly stated in the datasheet. However, according to Ohmite's application notes, the thermal resistance of similar resistors in the same package is around 10°C/W. It's recommended to consult with Ohmite's technical support for specific thermal resistance values.
  • Yes, the B20J12K5E resistor is RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) compliant, meeting the requirements of the European Union's directives for environmental protection.
