SMT35A-202LF

Arrays, Signal Transformers Overview

The SMT35A-202LF is an unshielded dual-coil inductor array manufactured by Gowanda Electronics. It features a surface-mount design with four leads and a nonstandard package configuration. The component provides two distinct inductance values depending on the connection topology: 80 µH when the coils are connected in series, and 20 µH when connected in parallel. The maximum DC resistance for this device is specified at 67 mOhms.

Arrays, Signal Transformers Feature Summary

• Dual-wound toroidal core construction for high efficiency
• Configurable inductance via series or parallel coil connections
• Surface-mount form factor with four-terminal interface

Arrays, Signal Transformers Applications

• Signal processing circuits requiring variable inductance
• Power filtering applications utilizing dual-coil configurations
• Compact electronic systems needing space-efficient magnetic components

Arrays, Signal Transformers Procurement Notes

Verify the specific suffix designation to confirm lead-free compliance and exact inductance tolerance. Confirm the package footprint dimensions against the target PCB layout to ensure mechanical compatibility. Cross-reference the manufacturer datasheet for thermal derating curves and saturation current limits before finalizing the bill of materials.

Arrays, Signal Transformers Selection Notes

Select this component when a single package must provide multiple inductance options through external circuit wiring. The dual-coil architecture allows designers to optimize for either higher inductance in series mode or lower resistance in parallel mode. Ensure the application can accommodate the physical size of the nonstandard surface-mount package.

Arrays, Signal Transformers Part Context

This part belongs to the SMT35A series of high-efficiency dual-wound toroidal inductors from Gowanda Electronics. The series includes variants with different nominal inductances, such as the SMT35A-152LF and SMT35A-332. These components are designed for demanding environments where compact size and magnetic shielding characteristics are critical for performance stability.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes include other Gowanda SMT35A series parts like the SMT35A-152LF or SMT35A-332 if the inductance value differs. Verify that any replacement maintains the same four-lead surface-mount footprint and toroidal core construction to preserve mechanical and electrical integration.
