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 30 V, it's essential to derate the voltage based on the application's operating frequency and temperature. As a general rule, keep the voltage stress below 25 V to ensure long-term reliability.
The 3224W-1-105E is rated for operation up to 125°C. However, it's crucial to consider the inductor's power dissipation and thermal resistance when operating in high-temperature environments. Ensure proper heat sinking and thermal management to prevent overheating.
To select the correct inductor value, consider the application's operating frequency, current requirements, and desired inductance value. Use Bourns' online inductor selection tools or consult with their application engineers for guidance.
