SMT45A-203

Arrays, Signal Transformers Overview

The SMT45A-203 is an unshielded dual-wound toroidal inductor array manufactured by Gowanda Electronics. It features two independent coils designed for surface-mount technology applications. The component offers configurable inductance values based on connection topology: 800 µH when the coils are connected in series, and 200 µH when connected in parallel. This flexibility allows designers to optimize circuit performance for specific filtering or energy storage requirements within compact electronic assemblies.

Arrays, Signal Transformers Feature Summary

• Dual-wound toroidal core construction for high efficiency
• Unshielded design suitable for non-interference environments
• Configurable inductance via series or parallel coil connections

Arrays, Signal Transformers Applications

• Signal processing circuits requiring variable inductance
• Power supply filtering stages
• Electronic assembly integration

Arrays, Signal Transformers Procurement Notes

Verify RoHS compliance status, specifically checking for LF suffix variants if lead-free requirements apply. Confirm moisture sensitivity level (MSL) ratings prior to soldering processes. Ensure package dimensions match PCB footprint specifications. Validate ECCN classification for export control purposes. Cross-reference datasheet electrical parameters against circuit design constraints.

Arrays, Signal Transformers Selection Notes

Select this component when flexible inductance adjustment is required without changing physical parts. Consider the unshielded nature for potential electromagnetic interference implications. Evaluate space constraints against the toroidal form factor. Ensure current ratings meet operational demands at both series and parallel configurations.
