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 electromagnetic interference, and optimize the component's performance.
To minimize electromagnetic interference, keep the inductor at least 5 mm away from sensitive components. You can also use shielding techniques, such as copper tape or mu-metal shielding, to contain the magnetic field.
Bourns recommends derating the voltage by 10-15% to ensure reliable operation. For the CM322522-220KL, this means not exceeding 198 V (90% of 220 V). Exceeding this voltage may reduce the inductor's lifespan or cause premature failure.
The CM322522-220KL is rated for operation up to 125°C. However, it's essential to consider the inductor's temperature coefficient and potential degradation at elevated temperatures. Consult Bourns' application notes for guidance on high-temperature operation.
The saturation current is not explicitly stated in the datasheet. To determine the saturation current, consult Bourns' application notes or contact their technical support. They can provide guidance on calculating the saturation current based on the inductor's design and your specific application.
