The recommended PCB land pattern for the 3443-32K is a rectangular pad with a size of 0.25 inches (6.4 mm) x 0.15 inches (3.8 mm) with a 0.05 inches (1.3 mm) spacing between pads.
The 3443-32K is rated for operation up to 125°C, but derating is required above 85°C. Consult the manufacturer's temperature derating chart for specific guidance.
The 3443-32K does not have built-in magnetic shielding. To minimize electromagnetic interference (EMI), use a shielded enclosure or add a mu-metal shield around the inductor.
The SRF of the 3443-32K is not specified in the datasheet, but it can be estimated to be around 100-150 MHz based on similar inductors from API Delevan.
The 3443-32K is designed to withstand moderate vibration levels. However, for high-vibration applications, consider using a more ruggedized inductor or adding additional mechanical support.
