Bourns provides a recommended PCB layout and land pattern in their application notes. It's essential to follow these guidelines to ensure proper thermal management, minimize parasitic inductance, and optimize performance.
To select the correct current rating, consider the maximum current required by your load, as well as any potential inrush currents or surges. Consult the datasheet for current rating options and consult with a Bourns representative if needed.
For high-power applications, ensure proper heat sinking and thermal management. The CD143A-SR70 has a thermal resistance of 2.5°C/W. Consider using a heat sink, thermal interface material, and ensuring good airflow to maintain a safe operating temperature.
Yes, the CD143A-SR70 is designed to meet CISPR 25 Class 5 emissions standards. However, it's essential to follow proper PCB layout and design practices to minimize EMI/EMC issues. Consult the datasheet and application notes for guidance.
Handle the CD143A-SR70 with care to prevent mechanical damage. Store them in a dry, cool place, away from direct sunlight and moisture. Follow standard ESD precautions when handling the components.
