SC104-270

Fixed Inductors Overview

The SC104-270 is a surface-mount power inductor from the SC104 series by Signal Transformer. It features an unshielded open-frame construction with a nominal inductance of 27 µH and a tolerance of ±20%. The component supports a saturation current of 1.44 A and a maximum DC current rating of 2.05 A. Its maximum DC resistance is 100 mΩ, and it is tested at a frequency of 2.52 MHz.

Fixed Inductors Feature Summary

• Open-frame construction for thermal efficiency
• Unshielded design to minimize core losses
• Surface-mount technology for automated assembly

Fixed Inductors Applications

• DC-DC converter output filtering
• Point-of-load regulation stages
• General-purpose power supply circuits

Fixed Inductors Procurement Notes

Verify the specific manufacturer designation, as sources list both Signal Transformer and Bel Signal Transformer. Confirm RoHS compliance status directly with the supplier. Ensure the ordering suffix matches the required packaging format, typically tape and reel, to align with production line requirements.

Fixed Inductors Selection Notes

Select this component when an unshielded inductor is acceptable to reduce magnetic interference with nearby sensitive traces. The 27 µH value suits moderate switching frequencies around 2.52 MHz. Evaluate the 100 mΩ DCR against system efficiency targets and ensure the 1.44 A saturation limit exceeds peak load currents.

Fixed Inductors Part Context

This part belongs to the SC Series of SMD power inductors manufactured by Signal Transformer. The series offers various inductance values ranging from 10 µH to 100 µH within the same footprint family. These components are designed for fixed inductor applications requiring high current handling in compact spaces.

Fixed Inductors Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify that any alternative maintains identical inductance, saturation current, and physical dimensions to ensure PCB compatibility without redesign.
