Current Sense Transformers Procurement Notes

Verify the specific suffix NLT against the manufacturer's latest datasheet to confirm packaging configuration and tape-and-reel specifications. Ensure that the 30 A primary current rating aligns with the peak load requirements of the target application circuit. Confirm RoHS compliance status through official documentation before finalizing procurement orders.

Current Sense Transformers Selection Notes

Select this component when a high-turns-ratio current transformer is required for precise current monitoring in compact designs. The 1.5:200 ratio provides significant signal amplification for low-side or high-side sensing applications. Consider the 9 mH inductance value to ensure adequate performance at the lower end of the 20 kHz operating frequency range.
