The thermal resistance of the RS0057R500FE73 is 250°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 RS0057R500FE73 is a thick-film resistor, which generally has a self-resonant frequency in the range of 100 MHz to 1 GHz. However, it's recommended to consult with Vishay's technical support or perform your own testing to ensure suitability for your specific high-frequency application.
Vishay's thick-film resistors, including the RS0057R500FE73, are designed to be resistant to sulfurization. However, it's essential to follow proper storage and handling procedures to minimize the risk of sulfurization.
Vishay recommends a soldering temperature of 260°C (500°F) for 10 seconds or less. It's essential to follow the recommended soldering profile to prevent damage to the resistor.
The RS0057R500FE73 is an industrial-grade resistor, but it's not specifically designed for automotive applications. If you need a resistor for an automotive application, consider using an AEC-Q200 qualified resistor, such as Vishay's Automotive Grade resistors.
