Fixed Inductors Procurement Notes

Verify the specific datasheet version to confirm exact DC resistance and saturation current values, as these parameters are critical for circuit design. Ensure the ordering suffix matches the required tolerance level. Confirm that the surface-mount footprint aligns with the PCB layout requirements before finalizing procurement orders.

Fixed Inductors Selection Notes

Select this component when a high-inductance value is required in a compact surface-mount form factor. The unshielded design may require consideration for electromagnetic interference in dense layouts. Compare against the broader CTGS137F series range to ensure the 820 µH rating meets the specific energy storage needs of the target application.

Fixed Inductors Part Context

This part belongs to the CTGS137F series of fixed inductors manufactured by Central Technologies. The series provides a wide range of inductance values suitable for various power electronics applications. The CTGS137F designation indicates a specific physical size and mounting style distinct from other Central Technologies inductor families like CTC5F or CTCH108F.

Fixed Inductors Replacement Considerations

Direct substitutes within the same series include CTGS137F-681K for lower inductance. Cross-series replacements must match the 13.00mm x 13.00mm footprint and similar current ratings. Verify that any alternative component maintains the unshielded characteristic if magnetic coupling is a concern.
