The component features a compact 4.5mm x 3.2mm footprint, suitable for space-constrained PCB layouts. It utilizes a composite core construction to minimize magnetic interference and provide stable inductance under DC bias conditions. The device is engineered for use in DC-DC converters and other power management circuits requiring reliable energy storage.

Feature Summary

• Shielded magnetic structure reduces electromagnetic interference
• Composite core material ensures low core losses
• Compact surface-mount package facilitates automated assembly

Applications

• DC-DC converter modules
• Point-of-load regulation circuits
• Portable electronic devices with tight space constraints

Procurement Notes

Verify the specific suffix 'Y' against the manufacturer's current datasheet to confirm tape-and-reel packaging specifications and terminal finish details. Ensure the ordering part number matches the required inductance tolerance and current ratings for your design. Cross-reference with official Bourns documentation to confirm RoHS compliance status and lead-free solderability requirements before finalizing procurement.

Selection Notes

Select this component based on its physical dimensions and shielding characteristics rather than generic family traits. Evaluate the DC resistance and saturation current limits relative to your circuit's peak load requirements. Consider the thermal performance and self-resonant frequency if operating at higher switching frequencies. Confirm that the available inductance values meet the filter design specifications without compromising efficiency.

Part Context

This part is part of Bourns' MH series of shielded power inductors. The series is characterized by its use of composite cores and shielded designs to enhance performance in noisy environments. These components are widely used in consumer electronics and industrial equipment where size reduction and EMI suppression are critical design drivers.

Replacement Considerations

Consult Bourns official substitution guides or equivalent manufacturer cross-reference lists for verified alternatives. Ensure any substitute maintains identical footprint, inductance value, and current handling capabilities. Verify compatibility with existing PCB layout and thermal management strategies before implementing changes.
