WSL2512R1400FEB - Vishay

WSL2512R1400FEB Frequently Asked Questions (FAQs)

• What is the thermal resistance of the WSL2512R1400FEB?
  The thermal resistance (Rth) of the WSL2512R1400FEB is 35°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 WSL2512R1400FEB resistor suitable for high-frequency applications?
  While the datasheet doesn't provide explicit information on high-frequency performance, the WSL2512R1400FEB is a thick-film resistor, which generally has a self-resonant frequency in the range of 100 MHz to 1 GHz. It may not be the best choice for very high-frequency applications (>1 GHz), but it can be suitable for frequencies up to a few hundred MHz.
• Can I use the WSL2512R1400FEB in a high-temperature environment?
  The WSL2512R1400FEB has a maximum operating temperature of 155°C, but its power rating derates above 70°C. It's essential to consider the temperature coefficient of resistance (TCR) and power derating when using this resistor in high-temperature environments.
• Is the WSL2512R1400FEB resistor suitable for pulse load applications?
  The WSL2512R1400FEB is designed for continuous operation, but it can handle pulse loads to some extent. However, the pulse duration, frequency, and amplitude will affect the resistor's performance and lifespan. It's recommended to consult Vishay's application notes or contact their support team for specific guidance on pulse load applications.
• What is the recommended land pattern for the WSL2512R1400FEB?
  The recommended land pattern for the WSL2512R1400FEB can be found in Vishay's package dimensions document or by contacting their support team. A general guideline is to use a land pattern with a minimum pad size of 1.5 mm x 3.5 mm and a solder mask clearance of 0.2 mm.
