Current Sense Transformers Procurement Notes

Verify that the specific suffix TR indicates tape and reel packaging as required for your automated placement equipment. Confirm that the 7 A current rating aligns with your peak load requirements. Ensure the 30:1 ratio matches your signal conditioning circuit design. Check that the invasive topology fits your PCB layout constraints.

Current Sense Transformers Selection Notes

Select this component when a high-frequency current transformer with a 30:1 ratio is required. Consider the 7 A limit and 74 µH inductance for compatibility with your control loop. Evaluate the 4.7 x 3.65 mm footprint against available board space. Verify thermal performance at +125°C for your specific application environment.

Current Sense Transformers Part Context

This part belongs to the SCS series of current sense transformers designed for compact power electronics. It serves as an alternative to other ratios in the same family, such as the SCS-4-4-20T-TR or SCS-4-4-40T-TR, offering a specific 30:1 transformation factor for tailored signal scaling needs.

Current Sense Transformers Replacement Considerations

Direct substitutes within the same series include the SCS-4-4-20T-TR and SCS-4-4-40T-TR. These alternatives share identical physical dimensions and mounting styles but differ in turns ratio. Ensure the new ratio meets your voltage output requirements before substitution.
