Bourns recommends a symmetrical layout with a central pad for the inductor, and a minimum of 2 oz copper thickness for optimal thermal performance. A recommended land pattern is available in the Bourns application note AN-13.
The MF-NSML400/12-2 is designed to handle high-frequency switching up to 1 MHz. However, it's essential to consider the skin effect and proximity effect, which may impact inductor performance. Consult the Bourns application note AN-14 for guidance on high-frequency design considerations.
While the datasheet specifies a maximum voltage rating of 12V, the inductor can withstand voltage stress up to 1.5 times the rated voltage for short durations (less than 1 second). However, prolonged exposure to high voltage stress may reduce the inductor's lifespan.
The inductor is rated for operation up to 125°C. However, derating is recommended for temperatures above 100°C to ensure reliable performance. Consult the Bourns application note AN-15 for thermal derating guidelines.
To prevent damage, store the inductor in a dry, cool place, away from direct sunlight and moisture. Avoid bending, flexing, or twisting the leads, and handle the component by the body, not the leads. Follow the ESD precautions outlined in the Bourns application note AN-16.
