API Delevan recommends a symmetrical PCB layout with a solid ground plane underneath the inductor to minimize radiation and electromagnetic interference (EMI). Keep the PCB traces short and wide to reduce resistance and inductance.
The 3443-64K is rated for operation up to 125°C, but its inductance and Q factor may degrade at higher temperatures. API Delevan recommends derating the inductor's current rating by 1.5% per degree Celsius above 85°C to ensure reliable operation.
The SRF of the 3443-64K is not explicitly stated in the datasheet, but it can be estimated using the inductor's inductance and capacitance values. Typically, the SRF is around 100-200 MHz for this inductor.
Yes, the 3443-64K is suitable for switching regulator applications due to its low core loss and high current handling capability. However, ensure that the inductor is properly sized for the specific application and that the switching frequency is within the inductor's recommended range.
API Delevan recommends storing the inductors in their original packaging, away from direct sunlight and moisture. Handle the inductors by the body, avoiding touching the leads or core to prevent damage or electrical discharge.
