GA3550-BLD Frequently Asked Questions (FAQs)

Coilcraft recommends a symmetrical PCB layout with a solid ground plane underneath the inductor to minimize radiation and ensure optimal performance. A minimum of 0.5 mm clearance around the inductor is recommended to prevent electromagnetic interference.
The GA3550-BLD has a maximum operating temperature of 125°C. Ensure good airflow around the inductor, and consider using a heat sink or thermal pad if the ambient temperature exceeds 85°C. Derate the current rating according to the temperature derating curve in the datasheet.
The SRF of the GA3550-BLD is not explicitly stated in the datasheet. However, Coilcraft provides an SRF calculator tool on their website, which estimates the SRF to be around 150-200 MHz for this specific inductor.
The GA3550-BLD is designed to withstand moderate vibration levels. However, if your application involves extreme vibration, consider using a more ruggedized inductor or adding additional mechanical support to prevent damage or electrical failure.
Coilcraft's GA3550-BLD is a high-reliability component, but it's essential to follow proper storage, handling, and soldering procedures to prevent damage. Ensure that your manufacturing process meets the requirements outlined in the datasheet and industry standards.
