It utilizes invasive terminals and conforms to AEC-Q200 qualification standards.

Current Sense Transformers Feature Summary

• Provides galvanic isolation with a precise 1:70 turns ratio for accurate current sensing
• Optimized for high-frequency operation between 50kHz and 1MHz
• Features low primary DC resistance to minimize insertion loss
• Qualified under AEC-Q200 automotive reliability standards

Current Sense Transformers Applications

• Battery Management Systems (BMS)
• Automotive power electronics
• High-frequency current monitoring circuits
• Inverter control systems

Current Sense Transformers Procurement Notes

Verify that the specific suffix 'QNL' denotes AEC-Q200 qualification and tray packaging, distinct from non-qualified variants. Confirm invasive terminal compatibility during PCB layout. Ensure operating frequency remains within the specified 50kHz to 1MHz range for optimal performance.

Current Sense Transformers Selection Notes

Select this component when a 20 A rating and 1:70 transformation ratio are required for invasive current sensing. Consider the 980 µH inductance and 0.75 mOhm primary resistance for circuit design. Verify AEC-Q200 compliance if automotive application requirements mandate it.

Current Sense Transformers Part Context

This part belongs to the PA1005 series of SMT current sense transformers from Pulse Electronics. The series offers various turns ratios and is characterized by its compact surface-mount footprint and robust construction suitable for demanding industrial and automotive environments.

Current Sense Transformers Replacement Considerations

PA1005.070NLT serves as a functional alternative with identical electrical specifications but lacks AEC-Q200 qualification and uses reel packaging instead of trays.
