Procurement Notes

Verify the specific suffix '-B' against official manufacturer documentation to confirm packaging details, as designations may indicate bulk packaging variations. Ensure that the through-hole mounting style and radial lead configuration align with your printed circuit board layout requirements before finalizing procurement orders.

Selection Notes

Select this component when a high-isolation current sense transformer is required for low-frequency applications. The 1000:1 ratio suits scenarios needing significant signal attenuation for measurement purposes. Confirm that the 46 Ohm impedance and 30.2 mm height fit within the available spatial constraints of the target enclosure or assembly.

Part Context

This part belongs to the Triad Magnetics transformer portfolio, specifically categorized under current sense transformers. It complements other magnetic components like common mode chokes and audio transformers offered by the same manufacturer, serving distinct roles in signal conditioning and power management within broader electronic system designs.

Replacement Considerations

Consult official Triad Magnetics substitution guides for verified alternatives. Cross-reference electrical parameters such as the 1000:1 ratio and 46 Ohm resistance to ensure functional equivalence without compromising circuit performance or safety compliance.
