WSR21R000FBA Frequently Asked Questions (FAQs)

  • The recommended soldering temperature for WSR21R000FBA is 260°C (500°F) for 10 seconds, with a peak temperature of 270°C (520°F) for 5 seconds.
  • Yes, the WSR21R000FBA is a wirewound resistor designed for high-frequency applications up to 50 MHz. Its wirewound construction and metal film technology provide low inductance and high frequency stability.
  • The WSR21R000FBA has a maximum operating temperature of 155°C (311°F). While it can tolerate high temperatures, it's essential to derate the power according to the temperature derating curve provided in the datasheet to ensure reliable operation.
  • Handle the WSR21R000FBA resistor by the body, avoiding touching the leads or wirewound area to prevent damage. Use anti-static precautions and follow standard ESD handling procedures to prevent electrostatic discharge damage.
  • Yes, the WSR21R000FBA resistor is RoHS (Restriction of Hazardous Substances) and REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) compliant, meeting the requirements for lead-free and hazardous substance-free components.
