Bourns recommends a symmetrical layout with a ground plane underneath the inductor to minimize radiation losses. A recommended land pattern is available in the Bourns application note AN-13.
The 3540S-1-202L is designed to handle high-frequency switching up to 1 MHz. However, it's essential to consider the skin effect and proximity effect, which can impact inductor performance. Consult the Bourns application note AN-12 for guidance on high-frequency design considerations.
The maximum allowable current for the 3540S-1-202L is 2.5 A. Exceeding this current can cause inductance to decrease due to saturation. Refer to the datasheet's current vs. inductance curve to determine the acceptable operating range.
The 3540S-1-202L is rated for operation up to 125°C. Derating factors are provided in the datasheet, and it's essential to consider these factors when operating the inductor in high-temperature environments.
Bourns recommends storing 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, to prevent damage.
