TX1281

Overview

The TX1281 is a surface mount pulse transformer manufactured by Pulse Electronics Corporation. It is designed for T1, CEPT, and ISDN-Pri applications. The component features a turns ratio of 1CT:1 and an inductance of 2mH. It has a primary impedance of 2.7 Ohms. The device operates within a temperature range of 0°C to 70°C. Its physical dimensions are 5.59mm in length, 5.08mm in height, and 15.24mm in width.

Feature Summary

Provides electrical isolation for T1, CEPT, and ISDN-Pri signal transmission
Optimized for surface mount assembly processes
Maintains signal integrity for demanding digital communication standards

Applications

T1 line interface circuits
CEPT standard telecommunication equipment
ISDN Primary Rate Interface (PRI) systems

Procurement Notes

Verify the specific datasheet version before procurement to ensure compatibility with current manufacturing standards. Confirm that the surface mount footprint matches the target PCB design. Check RoHS compliance status if required by regional regulations. Ensure storage conditions adhere to moisture sensitivity level requirements prior to reflow soldering.

Selection Notes

Select this component when designing interfaces for T1, CEPT, or ISDN-Pri networks requiring a 2mH inductance. The 2.7 Ohm impedance must match the transceiver specifications. Consider the 0°C to 70°C operating temperature range against environmental conditions. Verify the surface mount package dimensions fit the available board space constraints.

Part Context

This part belongs to the Pulse Electronics audio and signal transformer category. It serves as a discrete module for network isolation. The component supports high-frequency signal transmission while providing necessary galvanic isolation between circuit stages.

Replacement Considerations

Consult official distributor databases for verified substitute part numbers from Pulse Electronics or other manufacturers. Ensure any replacement maintains identical inductance, impedance, and physical footprint specifications.
