Current Sense Transformers Procurement Notes

Verify the specific manufacturer datasheet to confirm exact secondary resistance values, as third-party listings may vary. Ensure the selected variant matches the required 1:50 turns ratio and 1.7 mH inductance specifications. Confirm that the operating temperature range meets the thermal requirements of the target application environment before finalizing procurement.

Current Sense Transformers Selection Notes

Select this component when high-frequency current sensing at 20 kHz is required alongside robust electrical isolation. The 30 A current rating suits high-power applications. Verify that the physical dimensions and footprint are compatible with the PCB layout constraints. Consider the AEC-Q200 certification if the design targets automotive supply chains or stringent reliability standards.

Current Sense Transformers Part Context

This part belongs to the PH9505 series of SMT current sense transformers from Pulse Electronics. The series offers various turns ratios and inductance values tailored for different current levels. The PH9505.050NLT specifically addresses applications needing moderate current sensing with high isolation, distinguishing it from lower-voltage or non-automotive grade alternatives.

Current Sense Transformers Replacement Considerations

Cross-reference with other AEC-Q200 qualified current sense transformers offering similar 1:50 ratios and 3 kVdc isolation. Ensure substitute parts match the 30 A primary current rating and 20 kHz operational frequency. Verify mechanical compatibility and pinout alignment to prevent PCB redesign.
