PA1267NL

Overview

The PA1267NL is a board-mount power transformer manufactured by Pulse Electronics. It features an inductance of 155.5µH with a 7% tolerance and utilizes an EP13 core structure. The component supports surface mount technology (SMD/SMT) for PCB integration. It operates within a temperature range of -40°C to +125°C and complies with RoHS standards. This isolation transformer is designed for specific power and data interface applications.

Feature Summary

• Provides electrical isolation for power and data interfaces
• Engineered with EP13 core structure for efficient magnetic performance
• Supports surface mount assembly for automated PCB manufacturing

Applications

• Power over Ethernet (PoE) systems
• Data interface circuits requiring galvanic isolation
• Board-mount power transformer modules

Procurement Notes

Verify the exact part number suffix, as variants like NLT may indicate different packaging configurations such as reels or cut tape compared to standard tubes. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before placing orders to ensure supply chain alignment.

Selection Notes

Select this component when designing circuits requiring a 155.5µH inductance with tight 7% tolerance. Ensure the design accommodates the EP13 package dimensions and SMD mounting requirements. Verify that the operating temperature range of -40°C to +125°C meets the environmental specifications of the target application.

Part Context

This component belongs to the Pulse Electronics LAN and Power Transformers category. It serves as a critical passive element for signal integrity and power delivery in networked electronic devices. The product line emphasizes reliability and compliance with international environmental standards for modern electronics manufacturing.

Replacement Considerations

The PA1267NLT is a documented variant of this series, typically differing in packaging format rather than electrical function. Verify pin compatibility and mechanical footprint before substituting any alternative transformers from other manufacturers.
