Sumida Corporation provides a recommended PCB layout and footprint in their application notes, which can be obtained by contacting their technical support team. The recommended layout ensures optimal performance, reduced electromagnetic interference (EMI), and improved thermal management.
To minimize magnetic field interference, keep the inductor at least 5 mm away from nearby components, especially those sensitive to magnetic fields. Additionally, orient the inductor to minimize the magnetic field's impact on surrounding components. If necessary, use shielding or mu-metal to contain the magnetic field.
Sumida Corporation recommends derating the voltage by 10-15% to ensure reliable operation and prevent premature failure. This means that if the rated voltage is 24V, the maximum allowable voltage should not exceed 21.6V (24V - 10% of 24V).
Ensure good airflow around the inductor, and consider using a heat sink or thermal pad to improve heat dissipation. The inductor's thermal resistance (Rth) is specified in the datasheet; use this value to calculate the maximum allowable temperature rise. Keep the operating temperature below the maximum rated temperature to prevent thermal runaway and ensure reliable operation.
The 0624CDMCCDS-R08MC is designed for high-frequency switching applications. However, it's essential to consider the inductor's core losses, winding losses, and skin effect when operating at high frequencies. Consult Sumida Corporation's application notes or contact their technical support team for guidance on high-frequency operation.
