SCRH127B-820

Fixed Inductors Overview

The SCRH127B-820 is a surface-mount power inductor from the SCRH127B series manufactured by Signal Transformer. It features an 82 µH nominal inductance with a ±20% tolerance. The component has a maximum DC resistance of 160 mΩ and supports a saturation current of 2 A. It utilizes a ferrite core with wirewound construction and includes magnetic shielding to minimize electromagnetic interference. Designed for PCB mounting, it operates within a temperature range of -40°C to +125°C.

Fixed Inductors Procurement Notes

Verify the specific manufacturer designation, as sourcing data may reference Bel Signal Transformer or Signal Transformer. Confirm RoHS compliance status through official documentation. Ensure the ordering suffix matches the required electrical parameters. Check lead times as these components may be subject to special order requirements.

Fixed Inductors Selection Notes

Select this component when an 82 µH shielded inductor is required for space-constrained designs. The 160 mΩ DCR and 2 A saturation current define its power handling capabilities. Consider the 12.5 mm x 12.5 mm footprint for board layout compatibility. Verify thermal performance against the -40°C to +125°C operating range.

Fixed Inductors Part Context

This part belongs to the SCRH127B series of fixed surface-mount inductors. It shares physical dimensions with other variants in the family but differs in inductance and current ratings. The series is designed for high-reliability power applications requiring compact shielding solutions.

Fixed Inductors Replacement Considerations

Cross-reference with SCRH127-820 if similar specifications are acceptable, noting potential differences in series designation. Verify that substitute parts match the 12.5 mm x 12.5 mm footprint and 8 mm height constraints.
