API Delevan recommends a 4-layer PCB with a solid ground plane and thermal vias to dissipate heat. A minimum of 2 oz copper thickness is recommended for the top and bottom layers. Additionally, a thermal pad with a minimum size of 0.5 inches x 0.5 inches is recommended for heat sinking.
API Delevan recommends using a soldering iron with a temperature range of 250°C to 260°C and a solder with a melting point of 180°C to 190°C. The inductor should be placed on the PCB with the terminals facing downwards, and the solder should be applied in a smooth, continuous motion to avoid cold solder joints.
The CM6460-105 is designed to operate at a maximum voltage of 105V. However, API Delevan recommends derating the voltage by 10% to ensure reliable operation. Therefore, the maximum allowable voltage stress is 94.5V.
To minimize the effects of the magnetic field, API Delevan recommends keeping the inductor at least 0.5 inches away from other components and using a shielded layout to contain the magnetic field. Additionally, orienting the inductor's axis perpendicular to the PCB can help reduce the magnetic field's impact.
The CM6460-105 has a self-resonant frequency (SRF) of approximately 150 MHz. The SRF can affect the circuit design by causing the inductor to behave like a capacitor at frequencies above the SRF. To avoid this, API Delevan recommends using the inductor below its SRF or adding a damping resistor in series with the inductor to reduce the Q factor.
