Fixed Inductors Procurement Notes

Verify the specific suffix '1R2M' corresponds to the 1.2 µH inductance value during procurement. Confirm that the 41 mΩ DCR specification aligns with your circuit's efficiency requirements. Ensure the 1.76 A current ratings meet the peak and continuous load demands of the target application to prevent saturation or thermal issues.

Fixed Inductors Selection Notes

Select this component when a small form factor is required alongside moderate current handling capabilities. The shielded design makes it suitable for noise-sensitive environments where stray magnetic fields must be contained. Compare its 41 mΩ resistance against alternatives if minimizing conduction losses is a primary design constraint.

Fixed Inductors Part Context

This part belongs to the CTSPI2D18F series of shielded power inductors manufactured by Central Technologies. The series provides various inductance values within the same 2.0x1.8mm footprint, allowing designers to standardize board space while adjusting electrical characteristics. It complements other passive components in modern electronic systems requiring efficient power management.

Fixed Inductors Replacement Considerations

Direct substitutes include other 1.2 µH shielded SMD inductors with similar 2.0x1.8mm dimensions and comparable current ratings. Verify that any replacement maintains the 41 mΩ DCR maximum and 1.76 A current limits to ensure equivalent performance in the existing circuit topology.
