Current Sense Transformers Procurement Notes

Verify the specific package variant and tape-and-reel configuration required for your assembly line before ordering. Confirm that the supplier provides traceable documentation matching the iNRCORE part number PL3260. Ensure storage conditions comply with moisture sensitivity level requirements to maintain component integrity prior to soldering.

Current Sense Transformers Selection Notes

Select this component when high-frequency current sensing is required in space-constrained designs. The 1:40 turns ratio suits applications needing precise current replication without excessive secondary loading. Consider the thermal rating of +130°C for environments with elevated ambient temperatures. Verify that the 20A rated current aligns with the peak load expectations of the target circuit topology.

Current Sense Transformers Part Context

The PL3260 belongs to iNRCORE's SMT Current Sense Transformer series, designed for modern power electronics. It replaces through-hole alternatives by offering a low-profile footprint while maintaining ruggedized magnetic performance. This series addresses the industry demand for compact, isolated current feedback solutions in dense PCB layouts.

Current Sense Transformers Replacement Considerations

No direct public substitute part numbers are confirmed for the PL3260. Cross-reference with other iNRCORE current transformers only if dimensional and electrical parameters match exactly. Verify compatibility with existing board footprints and isolation requirements before considering alternative sources.
