The recommended PCB land pattern for the 5500R-336K is a rectangular pad with a minimum size of 0.25 inches (6.4 mm) x 0.15 inches (3.8 mm) and a maximum size of 0.35 inches (8.9 mm) x 0.25 inches (6.4 mm), with a non-solder mask defined (NSMD) pad shape.
To handle thermal considerations, ensure good airflow around the inductor, keep it away from heat sources, and use a thermal interface material (TIM) with a thermal conductivity of at least 1 W/m-K between the inductor and the PCB. Also, consider using a heat sink or a thermal pad if the application requires high current or high ambient temperatures.
The current rating derating curve for the 5500R-336K is typically provided by the manufacturer upon request. However, as a general guideline, the current rating derates by 1.5% per degree Celsius above 40°C. For example, at 50°C, the current rating would be approximately 92.5% of the rated value.
Yes, the 5500R-336K is designed to withstand vibrations up to 10 G peak acceleration, 10-2000 Hz frequency range, and 1.5 mm peak-to-peak displacement. However, it's essential to ensure proper PCB mounting and secure the inductor to prevent movement or damage during vibration.
To ensure magnetic shielding, keep the inductor at least 0.5 mm away from other magnetic components, and use a magnetic shield or a mu-metal shield around the inductor if necessary. Additionally, orient the inductor to minimize magnetic field interaction with other components.
