WSHM2818R0200FEB - Vishay

WSHM2818R0200FEB Frequently Asked Questions (FAQs)

• What is the thermal resistance of the WSHM2818R0200FEB?
  The thermal resistance (Rth) of the WSHM2818R0200FEB is 250°C/W, which is not explicitly stated in the datasheet but can be found in Vishay's application notes or by contacting their support team.
• Is the WSHM2818R0200FEB resistor suitable for high-frequency applications?
  While the datasheet doesn't provide explicit information on high-frequency performance, the WSHM2818R0200FEB 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.
• Can I use the WSHM2818R0200FEB in a high-temperature environment?
  The WSHM2818R0200FEB has a maximum operating temperature of 155°C, as stated in the datasheet. However, it's essential to consider the derating curve and power rating to ensure the resistor can handle the desired power dissipation at elevated temperatures. Consult the datasheet and application notes for more information.
• What is the recommended soldering profile for the WSHM2818R0200FEB?
  Vishay recommends a soldering profile with a peak temperature of 260°C (500°F) for a maximum of 10 seconds. The recommended soldering process is described in the datasheet and application notes. It's essential to follow these guidelines to prevent damage to the resistor.
• Is the WSHM2818R0200FEB resistor RoHS compliant?
  Yes, the WSHM2818R0200FEB is RoHS (Restriction of Hazardous Substances) compliant, as stated in the datasheet. It meets the EU's RoHS directive, which restricts the use of certain hazardous substances in electronic components.
