PE-51718

Current Sense Transformers Overview

The PE-51718 is a through-hole current sense transformer manufactured by Pulse Electronics. It features a solid core design with an inductance of 20 mH and a DC resistance of 200 Ohms. The component supports a current rating of 20 A and operates within a frequency range of 20 kHz to 200 kHz. Physical dimensions are approximately 22.86 mm in length, 17.78 mm in width, and 20.32 mm in height.

Current Sense Transformers Feature Summary

• Non-invasive solid core construction for board mount current sensing applications
• Designed for high-frequency operation between 20 kHz and 200 kHz
• Through-hole termination style for standard PCB integration

Current Sense Transformers Applications

• Switch-mode power supply current monitoring
• Inverter control circuitry feedback loops
• High-frequency AC current measurement systems

Current Sense Transformers Procurement Notes

Verify the specific datasheet version for the PE-51718 to confirm RoHS compliance status and exact pinout configurations before finalizing designs. Ensure that the operating temperature range aligns with the intended environmental conditions. Cross-reference the manufacturer's latest documentation to validate mechanical tolerances and mounting requirements for the printed circuit board layout.

Current Sense Transformers Selection Notes

Select this component when a non-invasive current sensing solution is required for frequencies up to 200 kHz. The 20 A rating suits moderate power applications. Compare against the PE-51719NL if higher inductance (80 mH) is needed. Ensure the through-hole package fits the available PCB space and that the 200 Ohm DC resistance meets the circuit's impedance constraints.

Current Sense Transformers Part Context

This part belongs to Pulse Electronics' series of through-hole current sense transformers and inductors. These components are engineered for precise current monitoring in electronic circuits without breaking the conductor path. The product line typically includes variants with different inductance values to suit various frequency and sensitivity requirements in power electronics.

Current Sense Transformers Replacement Considerations

The PE-51719NL serves as a related variant with 80 mH inductance. Verify compatibility regarding inductance differences and physical footprint before substitution. No other direct substitute part numbers are confirmed in public documentation.
