PA2467NL

Overview

The PA2467NL is a surface-mount pulse transformer manufactured by Pulse Electronics, designed for board mounting applications. It features an EP13 core configuration and supports flyback topologies with an input voltage range of 37V to 57V. The component delivers an output power of 25.2W and includes a primary inductance of 37µH. Electrical characteristics include a primary DC resistance of 0.089 Ohms and a secondary DC resistance of 0.0028 Ohms. It utilizes a gull-wing SMD package with ten terminals and provides 1500V isolation.

Feature Summary

• Supports flyback switching transformer configurations with specified turns ratios
• Features gull-wing surface mount termination for automated assembly
• Provides high-voltage isolation between primary and secondary circuits

Applications

• Flyback power supply designs
• Board-mounted switching transformer circuits
• Power conversion systems requiring 37V-57V input ranges

Procurement Notes

Verify the specific datasheet version to confirm terminal count and resistance values, as distributor listings may vary. Ensure the EP13 package dimensions match the target PCB footprint. Confirm RoHS compliance status through official manufacturer documentation prior to integration.

Selection Notes

Select this component for applications requiring a 37µH primary inductance and 25.2W power handling capability. The EP13 form factor suits space-constrained designs. Verify that the 0.089 Ohm primary DCR meets thermal requirements. Ensure the 1500V isolation rating aligns with safety standards for the intended voltage domain.

Part Context

This part belongs to the Pulse Electronics line of surface-mount power transformers. It is distinct from their LAN signal transformers, such as the E2467NL series. The PA2467NL serves power electronics rather than data communication interfaces, utilizing magnetic components optimized for energy transfer in switching regulators.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with other EP13-based flyback transformers only if electrical parameters and pinout compatibility are verified against official manufacturer substitution lists.
