Fixed Inductors Procurement Notes

Verify the specific ordering suffix and packaging configuration when sourcing. Confirm that the component meets the required thermal and electrical specifications for the target application environment. Ensure compatibility with standard surface-mount assembly processes and check for any updated replacement models within the manufacturer's portfolio before finalizing procurement plans.

Fixed Inductors Selection Notes

Select this component based on the required 1.2 µH inductance and 390 mA current handling capability. Evaluate the 750 mΩ DC resistance against power loss constraints. The 1210 package size must align with available board space. Consider the unshielded nature of the design regarding potential electromagnetic interference in sensitive nearby circuits.

Fixed Inductors Part Context

This part belongs to the PM20 series of fixed inductors manufactured by Bourns Inc. The series is characterized by its small form factor and suitability for surface-mount technology. These components are typically utilized in applications requiring moderate inductance values within tight spatial limitations, serving as essential passive elements in modern electronic assemblies.

Fixed Inductors Replacement Considerations

Public records indicate that Model PM20 series products may be replaced by Model CM322522. Verify if the CM322522 variant meets the specific electrical requirements of the original design before substitution.
