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.
While the datasheet only specifies up to 1 MHz, the 3386X-1-501LF can be used up to 10 MHz with some degradation in inductance and Q factor. However, it's recommended to consult with Bourns' application engineers for specific high-frequency requirements.
The maximum allowable current is not explicitly stated in the datasheet, but it's limited by the inductor's thermal resistance and the PCB's thermal design. As a general guideline, the inductor can handle up to 2.5 A RMS current, but this may vary depending on the specific application and thermal environment.
The 3386X-1-501LF is rated for operation up to 125°C, but the inductor's performance may degrade above 100°C. For high-temperature applications, it's recommended to consult with Bourns' application engineers to discuss potential derating and custom solutions.
While not explicitly stated in the datasheet, it's recommended to provide a solid ground plane under the inductor and to use a shielded layout to minimize EMI radiation. Additionally, a 0.1 μF decoupling capacitor can be added in parallel with the inductor to reduce high-frequency noise.
