PE-67100

Current Sense Transformers Overview

The PE-67100 is a through-hole current sense transformer manufactured by Pulse Electronics. It features a single-turn primary winding and supports a maximum current rating of 37 A. The device operates within a frequency range of 10 kHz to 200 kHz. Electrical specifications include a primary DC resistance of 56 ohms, a secondary DC resistance of 1.4 ohms, and an inductance of 20 mH. The unit utilizes a 1:100 turns ratio and is designed for invasive installation methods.

Current Sense Transformers Feature Summary

• Provides galvanic isolation between the primary circuit and secondary sensing electronics
• Supports high-frequency signal transmission within the specified operational bandwidth
• Utilizes a robust 130°C insulation system for thermal stability

Current Sense Transformers Applications

• Current monitoring in power supply circuits
• Overcurrent protection systems
• Closed-loop control applications requiring precise current feedback

Current Sense Transformers Procurement Notes

Verify the specific suffix (e.g., NL) against the datasheet to confirm compliance with environmental standards such as RoHS. Ensure the selected variant matches the required mounting style and electrical ratings for the target application. Cross-reference manufacturer part numbers with distributor codes to avoid ordering errors due to naming conventions or obsolete listings.

Current Sense Transformers Selection Notes

Select this component when a 1:100 turns ratio and 37 A continuous current rating are required. Consider the 56 ohm primary impedance and 20 mH inductance for circuit compatibility. Verify that the through-hole package dimensions fit the PCB layout constraints. Confirm that the operating temperature range meets the environmental requirements of the final assembly.

Current Sense Transformers Part Context

This component belongs to the PE-67xxx series of current sense transformers from Pulse Electronics. These devices are engineered for reliable performance in power management applications. The series offers various current ratings and turns ratios to accommodate different design needs while maintaining consistent physical form factors and installation characteristics across the product line.

Current Sense Transformers Replacement Considerations

The PE-67100NL is a verified equivalent variant offering identical electrical specifications with updated environmental compliance. Other models in the PE-67 series may serve as alternatives if different current ratings or turns ratios are acceptable for the design.
