SMT35A-202

Arrays, Signal Transformers Overview

The SMT35A-202 is a high-efficiency dual-wound toroidal inductor from Gowanda Electronics, designed for surface-mount applications. It features an unshielded construction with two coils connected in series, providing a total inductance of 80 µH. When connected in parallel, the configuration yields 20 µH. The component operates within a temperature range of -55°C to 125°C and utilizes standard terminations on a non-standard four-lead package measuring 0.392 inches by 0.392 inches.

Arrays, Signal Transformers Procurement Notes

Verify the specific suffix (e.g., LF) against your bill of materials, as it may indicate lead-free compliance or packaging variations. Confirm the required inductance configuration (series vs. parallel) matches the schematic design. Ensure the non-standard footprint dimensions are compatible with the PCB land pattern. Check termination type compatibility with the soldering process used in production.

Arrays, Signal Transformers Selection Notes

Select this component when a compact, high-efficiency dual-inductor solution is required for space-constrained designs. The dual-wound structure allows for versatile circuit topologies using a single footprint. Consider the unshielded nature if stray magnetic fields do not interfere with nearby sensitive components. Evaluate the thermal performance within the specified -55°C to 125°C range for the intended operating environment.
