PM2165.020NL

Current Sense Transformers Overview

The PM2165.020NL is a surface-mount current sense transformer from Pulse Electronics, designed for board-level integration. It features a 1:20 turns ratio and supports primary currents up to 20A within an EE8 platform. The component exhibits a maximum primary DC resistance of 0.75mOhm and a secondary DC resistance of 550mOhm. Inductance is specified at 80µH. Physical dimensions are 13mm x 10.5mm x 7.2mm. It serves as a low-loss method for sensing AC current in electronic circuits.

Current Sense Transformers Feature Summary

• Provides accurate current sensing with a 1:20 transformation ratio
• Optimized for low power loss via minimal primary DC resistance
• Compact footprint suitable for space-constrained PCB layouts

Current Sense Transformers Applications

• AC current measurement in power supply circuits
• Current monitoring in EE8 platform applications
• Low-loss sensing solutions for electronic systems

Current Sense Transformers Procurement Notes

Verify the specific suffix 'NL' against official datasheets to confirm lead-free compliance and packaging details. Confirm that the 1:20 ratio matches the design requirements, as other variants like PM2165.100NL offer different ratios. Check availability status as distribution channels may report limited stock or restricted sales regions. Ensure the 20A rating aligns with peak operational currents.

Current Sense Transformers Selection Notes

Select this model when a 1:20 ratio is required for current sensing. Compare the 80µH inductance against circuit bandwidth needs. Evaluate the 13mm x 10.5mm footprint against available PCB space. Consider the 0.75mOhm primary DCR for thermal management. Verify compatibility with SMD assembly processes and ensure the 20A current rating covers maximum load conditions.

Current Sense Transformers Part Context

This component belongs to the PM2165 series of current transformers by Pulse Electronics. Variants such as PM2165.100NL and PM2165.100NLT share similar physical characteristics but differ significantly in electrical specifications, particularly the turns ratio (1:100) and inductance values. The series utilizes an EE8 core structure optimized for surface mount technology.

Current Sense Transformers Replacement Considerations

PM2165.100NL and PM2165.100NLT are related parts within the same series but feature a 1:100 ratio instead of 1:20. These substitutions require circuit redesign due to differing transformation ratios and inductance values. Direct replacement is not electrically equivalent without adjusting downstream signal conditioning.
