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 4609X-101-681LF 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-12 for guidance on high-frequency design considerations.
While the datasheet specifies a maximum rated voltage of 50 V, the inductor can withstand voltage spikes up to 100 V for short durations (less than 1 ms). However, continuous operation above 50 V is not recommended.
The 4609X-101-681LF uses a ferrite core, which provides a high saturation point and low core losses. This results in improved efficiency and reduced heat generation. However, ferrite cores can be prone to core saturation at high currents, so ensure proper current derating and thermal management.
Yes, to prevent damage, store the inductor in a dry, cool place, away from direct sunlight and moisture. Avoid bending or flexing the leads, and handle the component by the body, not the leads, to prevent mechanical stress.
