PB0026NL

Current Sense Transformers Overview

The PB0026NL is a surface-mount current sense transformer from Pulse Electronics, designed for high-frequency applications. It features a 100:1 turns ratio and supports a primary rated current of 35 A. The component operates within a frequency range of 50 kHz to 500 kHz. Electrical characteristics include a primary DC resistance of 0.42 mΩ, a secondary DC resistance of 1.4 Ω, and an inductance of 5.6 mH. The device utilizes gull-wing termination and measures 19.91 mm in length, 15 mm in width, and 10 mm in height.

Current Sense Transformers Feature Summary

• Provides galvanic isolation with a 100:1 current transformation ratio for accurate sensing.
• Engineered for high-frequency operation between 50 kHz and 500 kHz.
• Features low primary DC resistance to minimize insertion loss in high-current paths.

Current Sense Transformers Applications

• Current sensing in switch-mode power supplies
• Overcurrent protection circuits
• High-frequency motor drive systems

Current Sense Transformers Procurement Notes

Verify the specific package variant required, as the tape-and-reel version carries the suffix NLT. Confirm that the 35 A rating aligns with peak operational currents. Ensure PCB footprint matches the 19.91 mm by 15 mm dimensions. Check RoHS compliance status if environmental regulations apply to the final assembly.

Current Sense Transformers Selection Notes

Select this component when a compact, surface-mount solution is needed for currents up to 35 A. The 5.6 mH inductance suits frequencies starting at 50 kHz. Consider the 100:1 ratio for signal conditioning requirements. Verify thermal management capabilities given the low primary resistance.

Current Sense Transformers Part Context
