Fixed Inductors Procurement Notes

Verify component authenticity through authorized Bourns distributors or certified partners. Confirm that the received parts match the specific PM125S-561M designation and exhibit no physical damage. Ensure storage conditions maintain component integrity prior to assembly. Review the latest datasheet for any updates regarding material composition or environmental compliance statements before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a 560 µH inductance value is required within a shielded surface mount package. Consider the 440 mA current rating and 1.34 Ohm resistance limits against circuit requirements. Evaluate the 3 MHz self-resonant frequency to ensure suitability for the target operating bandwidth. Compare physical dimensions and thermal characteristics against available space constraints on the printed circuit board layout.

Fixed Inductors Part Context

The PM125S-561M belongs to the PM125S series of shielded SMD power inductors manufactured by Bourns Inc. This series was designed to provide reliable performance in compact electronic applications. Note that Bourns has announced discontinuation of the entire PM125S series due to declining sales volume and diminishing market demand, affecting long-term availability.

Fixed Inductors Replacement Considerations

Due to the discontinuation of the PM125S series, alternative components must be sourced. Verify electrical equivalence including inductance, current rating, and physical footprint. Consult official Bourns documentation for recommended substitute part numbers or transition plans to ensure compatibility with existing designs.
