MP821-4.00-1% - Caddock

MP821-4.00-1% Frequently Asked Questions (FAQs)

• What is the recommended power derating for high-temperature applications?
  Caddock recommends derating the power by 1% for every 1°C above 25°C to ensure reliable operation and prevent overheating.
• Can I use the MP821-4.00-1% in a high-humidity environment?
  While the MP821-4.00-1% is designed to operate in normal humidity conditions, it's not recommended for use in high-humidity environments (>80% RH) without proper protection or encapsulation to prevent moisture ingress and corrosion.
• What is the maximum allowable voltage imbalance between the input and output?
  Caddock recommends keeping the voltage imbalance between the input and output within 10% to ensure stable operation and prevent damage to the device.
• Can I use the MP821-4.00-1% in a high-vibration environment?
  The MP821-4.00-1% is designed to withstand normal vibration levels, but it's recommended to consult with Caddock or perform additional testing for high-vibration applications (>10g) to ensure reliable operation.
• What is the recommended PCB layout and thermal management for optimal performance?
  Caddock recommends following standard PCB layout practices for high-power resistors, including using a thermally conductive PCB material, providing adequate heat sinking, and keeping the component away from heat sources and airflow obstructions.
