PA1366NLT

Overview

The PA1366NLT is a surface-mount flyback transformer manufactured by Pulse Electronics, designed for board-level power applications. It features an EFD20 core configuration and utilizes Non-Plated Bottom (NPB) technology to facilitate thermal management and mounting flexibility. The component provides an inductance of 10 µH with a primary voltage range of 30 to 57 V and a secondary voltage of 48 V. It operates within a temperature range of -40°C to +125°C and complies with RoHS3 standards.

Feature Summary

• EFD20 core construction optimized for high-frequency flyback converter topologies
• Non-Plated Bottom (NPB) design enabling direct thermal dissipation to the PCB substrate
• Surface-mount package format supporting automated assembly processes

Applications

• Flyback power supply circuits
• Board-mounted isolated DC-DC conversion systems
• Commercial electronic power modules

Procurement Notes

Verify that the specific application requires the NPB (Non-Plated Bottom) termination style, as this affects thermal interface requirements compared to standard plated terminations. Confirm that the EFD20 core size aligns with the available PCB footprint and that the 10 µH primary inductance matches the target converter's magnetic design specifications before finalizing the order.

Selection Notes

Select this component when a compact flyback transformer with integrated thermal relief via the non-plated bottom is required. Ensure the operating voltage ranges of 30-57 V primary and 48 V secondary are compatible with the system architecture. Consider the -40°C to +125°C operating temperature range against the environmental conditions of the end product.

Part Context

This part belongs to the family of surface-mount power transformers from Pulse Electronics. It is specifically categorized as a flyback transformer utilizing the EFD20 core geometry. The designation indicates its role in isolated power conversion, distinct from general-purpose chokes or coupled inductors found in other series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Any replacement must be validated against electrical parameters, core geometry, and mechanical footprint compatibility.
