SMT45A-103LF

Arrays, Signal Transformers Overview

The SMT45A-103LF is an unshielded two-coil inductor array from Gowanda Electronics, designed for surface mount technology. It features a total inductance of 400 µH when coils are connected in series and 100 µH when connected in parallel. The component has a maximum DC resistance of 6 Ohms and supports a current rating of 1.37 A. Operating within a temperature range of -55°C to +125°C, it utilizes standard SMD/SMT termination styles suitable for PCB mounting.

Arrays, Signal Transformers Feature Summary

Arrays, Signal Transformers Procurement Notes

Verify the specific suffix designation (LF) to confirm lead-free compliance status as required by project specifications. Confirm that the unshielded nature aligns with electromagnetic interference constraints. Ensure the selected configuration (series or parallel) matches the target circuit impedance requirements before finalizing procurement orders.

Arrays, Signal Transformers Selection Notes

Select this component when a dual-inductor solution with configurable coupling is necessary. The unshielded design requires careful layout consideration to prevent magnetic interference with nearby sensitive components. Evaluate the 1.37 A current rating against peak load conditions to ensure reliable operation without saturation.

Arrays, Signal Transformers Part Context

This part belongs to the SMT45A series of surface mount inductor arrays. It serves as a modular passive component alternative to discrete single inductors, offering space savings on dense printed circuit boards while providing independent coil management capabilities for complex signal conditioning tasks.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes include other Gowanda SMT45A variants such as SMT45A-121LF or SMT45A-153LF if different inductance values are acceptable. Cross-manufacturer replacements require matching inductance, current rating, and physical footprint dimensions to ensure compatibility.
