TX1262NLT

Overview

The TX1262NLT is a surface-mount T1/E1/CEPT/ISDN-PRI transformer manufactured by Pulse Electronics. It features a 1:2 turns ratio for both transmitter and receiver channels. The component has a maximum DC resistance of 750 mOhms and an insulation voltage rating of 1.5 kV. Physical dimensions are 28.58 mm in length, 5.84 mm in height, and 6.99 mm in width. It operates within a temperature range of -40°C to +85°C.

Feature Summary

Supports T1, E1, CEPT, and ISDN-PRI signaling standards
Provides galvanic isolation with 1.5 kV insulation voltage
Designed for surface-mount assembly on printed circuit boards

Applications

T1 line interface circuits
E1 telecommunications equipment
ISDN-PRI terminal adapters
CEPT standard transmission systems

Procurement Notes

Verify the specific datasheet version and mechanical drawing against the target PCB footprint before procurement. Confirm that the 1:2 turns ratio aligns with the system's impedance matching requirements. Ensure the operating temperature range meets the environmental specifications of the final application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when designing interfaces for T1 or E1 digital transmission lines requiring a 1:2 transformation ratio. Consider the physical dimensions of 28.58 x 6.99 x 5.84 mm for board space constraints. Evaluate the thermal performance within the -40°C to +85°C range for industrial environments. Compare against other LAN transformers if the application requires Ethernet rather than telecom signaling.

Part Context

This component belongs to the Pulse Electronics transformer portfolio, specifically categorized under audio and signal transformers. It serves as a critical passive element in telecommunications hardware, facilitating signal integrity and isolation between network interfaces and processing units. The product line supports various industrial and commercial communication protocols.
