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 minimize electromagnetic interference (EMI), 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.
While the datasheet specifies a maximum rated voltage of 100V, it's essential to derate the voltage based on the application's operating frequency and temperature. As a general rule, derate the voltage by 10-20% to ensure reliable operation.
The CM322522-100KL is rated for operation up to 125°C. However, it's crucial to consider the inductor's power dissipation, PCB thermal conductivity, and airflow when operating in high-temperature environments. Ensure the inductor's temperature rating is not exceeded to prevent premature failure.
To select the correct inductor value, consider the application's operating frequency, current requirements, and desired inductance value. Use online inductor selection tools or consult with a Bourns application engineer to determine the optimal inductor value for your specific application.
