WSR21R000FEB Frequently Asked Questions (FAQs)
-
The thermal resistance of the WSR21R000FEB is 350°C/W, which is not explicitly stated in the datasheet. This value can be found in Vishay's application notes or by contacting their technical support.
-
While the datasheet doesn't provide explicit information on high-frequency performance, the WSR21R000FEB is a wirewound resistor, which generally has a self-resonant frequency in the range of 10-100 MHz. It may not be the best choice for very high-frequency applications (>100 MHz). For high-frequency applications, consider using a thin-film or thick-film resistor instead.
-
The WSR21R000FEB has a maximum operating temperature of 250°C, but it's essential to consider the derating curve provided in the datasheet. The resistor's power rating decreases significantly above 150°C. If you need a resistor for high-temperature applications, consider using a specialized high-temperature resistor or consulting with a Vishay application engineer.
-
Vishay recommends a soldering profile with a peak temperature of 260°C (500°F) for a maximum of 10 seconds. It's essential to follow a controlled soldering process to avoid damaging the resistor. Consult the datasheet or Vishay's application notes for more information on soldering guidelines.
-
The WSR21R000FEB is not AEC-Q200 qualified, which is a common requirement for automotive applications. If you need a resistor for automotive use, consider using a qualified component or consulting with a Vishay application engineer to find a suitable alternative.
