HVR2500005603FR500 - Vishay

HVR2500005603FR500 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for the HVR2500005603FR500?
  Vishay provides a recommended PCB layout and land pattern in their application note AN10273, which can be found on their website. It's essential to follow these guidelines to ensure proper thermal management and minimize thermal resistance.
• How do I handle the thermal interface material (TIM) for the HVR2500005603FR500?
  Vishay recommends using a thermal interface material (TIM) with a thermal conductivity of at least 1 W/m-K. The TIM should be applied evenly and thinly (typically 0.05 mm to 0.10 mm) to the base plate of the resistor. Vishay also provides a list of recommended TIMs in their application note AN10273.
• What is the maximum allowable voltage derating for the HVR2500005603FR500?
  The maximum allowable voltage derating for the HVR2500005603FR500 is 80% of the rated voltage. This means that if the resistor is rated for 560 V, the maximum allowable voltage derating would be 448 V (80% of 560 V).
• How do I ensure the HVR2500005603FR500 is properly cooled in my design?
  Proper cooling of the HVR2500005603FR500 can be achieved by ensuring good airflow around the resistor, using a heat sink if necessary, and following Vishay's recommended PCB layout and land pattern. Additionally, the thermal interface material (TIM) should be applied correctly, and the resistor should be mounted securely to the PCB or heat sink.
• What is the expected lifespan of the HVR2500005603FR500 under normal operating conditions?
  The expected lifespan of the HVR2500005603FR500 under normal operating conditions is typically in the range of 10 to 20 years, depending on the application and environmental factors. However, this can vary depending on the specific use case and operating conditions.
