PE-68280

Current Sense Transformers Overview

The PE-68280 is a surface-mount current sense transformer manufactured by Pulse Electronics, designed for high-frequency applications. It features a 1:1:100 turns ratio and operates within a frequency range of 50kHz to 500kHz. The device has a primary DC resistance of 1.15 milliohms and a secondary DC resistance of 930 milliohms. Its inductance is specified at 14.8 mH. The component measures 12.57mm in length, 12.45mm in width, and 7.11mm in height. It supports a current rating of 15A and utilizes an intrusive installation type.

Current Sense Transformers Feature Summary

• Provides precise current sensing through a dedicated 1:1:100 turns ratio configuration
• Optimized for high-frequency operation between 50kHz and 500kHz
• Features low primary DC resistance to minimize insertion loss
• Designed for surface-mount assembly on printed circuit boards

Current Sense Transformers Applications

• Current sensing in switching power supplies
• Gate drive circuits requiring isolated current feedback
• High-frequency power conversion systems
• Intrusive current monitoring in compact electronic designs

Current Sense Transformers Procurement Notes

Verify the specific suffix requirements when ordering, as the NL suffix denotes RoHS compliance according to manufacturer specifications. Confirm that the selected package variant matches the required tape and reel or cut tape format for automated assembly processes. Ensure the operating frequency range aligns with the system's switching speed to maintain accurate signal integrity during current measurement tasks.

Current Sense Transformers Selection Notes

Select this component when a high turns ratio is necessary for sensitive current detection in high-frequency environments. The low primary resistance makes it suitable for applications where minimizing voltage drop across the sensor is critical. Consider the physical dimensions and intrusive nature of the design to ensure compatibility with the target PCB layout and thermal management requirements.

Current Sense Transformers Part Context

This part belongs to the PE-68XXXNL series of current transformers from Pulse Electronics. It is distinct from other series like PE-68386, which are pulse transformers for gate drives, and PE-53802NL, which is a power inductor. The PE-68280 is specifically engineered for current sensing rather than general signal isolation or power storage functions.
