Arrays, Signal Transformers Procurement Notes

Verify the specific suffix 'LF' to confirm lead-free compliance status as per manufacturer documentation. Confirm that the standard termination type matches your PCB pad design requirements. Ensure the unshielded nature of the component does not interfere with nearby sensitive traces or components in your layout.

Arrays, Signal Transformers Selection Notes

Select this component when a dual-coil configuration is required for series or parallel operation. The 20 µH per coil rating suits applications needing adjustable inductance through wiring changes. Consider the 6 Ohm maximum DC resistance limit for efficiency requirements in power paths.

Arrays, Signal Transformers Part Context

This part belongs to the SMT45A series of high-efficiency dual-wound toroidal inductors from Gowanda Electronics. These components are designed for demanding applications requiring compact, high-performance inductive solutions in a surface-mount format.

Arrays, Signal Transformers Replacement Considerations

Direct substitutes must match the 20 µH per coil specification and SMD toroidal form factor. Verify equivalent DC resistance and current handling capabilities before substitution.
