PA2271NL

Overview

The PA2271NL is a surface-mount pulse transformer manufactured by Pulse Electronics, designed for board mounting applications. It features an EP13 core configuration and operates with a maximum power rating of 13W. The component exhibits an inductance of 10µH and supports a maximum operating frequency of 200kHz. Electrical characteristics include a secondary side maximum DC resistance (DCR) of 0.0067 Ohms. The device utilizes gull-wing lead style termination and is housed in a package measuring approximately 14.00mm in length and 13.11mm in width, with a maximum seated height of 0.551 inches.

Feature Summary

• Surface-mount construction utilizing gull-wing lead style termination for PCB integration
• EP13 core configuration optimized for pulse transformation applications
• Capable of handling a maximum power rating of 13W
• Operates within a defined frequency range up to 200kHz

Applications

• Power supply circuit design
• Isolated signal transmission systems
• Electronic equipment requiring surface-mount pulse transformers

Procurement Notes

Verify the specific datasheet version and mechanical dimensions prior to procurement, as supplier listings may vary slightly in reported parameters such as seating height or footprint area. Confirm RoHS compliance status directly with the manufacturer documentation. Ensure that the gull-wing lead style matches the target PCB land pattern requirements. Cross-reference the 13W power rating against actual thermal dissipation conditions in the final assembly to guarantee reliable operation under load.

Selection Notes

Select this component when a surface-mount pulse transformer with a 10µH inductance and 13W power handling capability is required. The EP13 core size and gull-wing termination are critical factors for compatibility with existing PCB footprints. Consider the 200kHz maximum operating frequency limit when designing high-speed switching circuits. The low secondary DCR of 0.0067 Ohms suggests suitability for applications where minimizing resistive losses is important for efficiency.

Part Context

The PA2271NL belongs to the Pulse Electronics transformer product line, specifically categorized under board-mount power transformers. It is distinct from common mode chokes found in other series due to its pulse transformation function rather than noise filtering. The component serves as a key isolation element in power electronics, differing from inductors by its magnetic coupling between primary and secondary windings. Its specifications align with standard industrial and commercial power conversion modules.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Verify mechanical footprint compatibility and electrical parameters such as inductance and power rating before considering alternative manufacturers. Consult official distributor databases for cross-reference data.
