PB0026

Current Sense Transformers Overview

The PB0026 is a surface-mount current sense transformer from Pulse Electronics, designed for high-current applications. It features a 100:1 turns ratio and supports a rated current of 35 A. The component operates within a frequency range of 50 kHz to 500 kHz. Primary DC resistance is 0.42 mOhm, while secondary DC resistance is 1.4 Ohm maximum. Inductance is 5.6 mH. Physical dimensions are 15.00 mm length, 19.91 mm width, and 10.00 mm height. It utilizes鸥翼 (gull-wing) terminals for PCB mounting.

Current Sense Transformers Feature Summary

• Surface-mount construction with gull-wing terminals for reliable PCB integration
• High current handling capability up to 35 A with 100:1 isolation ratio
• Optimized for switching frequencies between 50 kHz and 500 kHz

Current Sense Transformers Applications

• Current sensing in power supply circuits
• Overcurrent protection systems
• Industrial motor control applications

Current Sense Transformers Procurement Notes

Verify the specific suffix variant required, as PB0026NLT indicates tape and reel packaging. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as historical data suggests leaded versions may exist. Ensure the ordering part number matches the exact terminal style and packaging format needed for the assembly line. Cross-reference the datasheet for any recent updates to mechanical drawings or electrical tolerances before finalizing procurement.

Current Sense Transformers Selection Notes

Select this component when high-current isolation is required in a compact surface-mount form factor. The 100:1 ratio suits applications needing precise current monitoring without direct galvanic connection. Consider the 35 A rating against peak load requirements. The 5.6 mH inductance impacts low-frequency response; verify compatibility with the target switching frequency range of 50-500 kHz. Ensure PCB footprint accommodates the 19.91 x 15.00 mm outline and 10 mm height clearance.

Current Sense Transformers Part Context

The PB0026 belongs to Pulse Electronics' SMT Current Sense Transformers series. It is manufactured by Pulse, a Technitrol Company. This component serves as an alternative to through-hole current transformers, offering space savings and automated assembly compatibility. It is distinct from Pulse's inductor and RF cable product lines.

Current Sense Transformers Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs using equivalent specifications such as 100:1 ratio, 35 A rating, and compatible package dimensions.
