HX1236T

Overview

The HX1236T is a quad-port pulse transformer module designed for 10/100Base-TX LAN applications. It features four independent 1:1 transmitter and receiver channels. The component supports extended temperature operation, serving as an enhanced variant of the H1036L series. Physical dimensions are specified as 1.125 inches in length by 0.480 inches in width. The device utilizes surface mount technology for integration into network interface circuits.

Feature Summary

• Quad-port architecture supporting simultaneous 10/100Base-TX transmission and reception
• Extended temperature range capability compared to standard series variants
• Integrated common mode choke functionality within a compact surface mount package

Applications

• Ethernet network interface cards (NICs)
• Industrial LAN communication modules
• Network switch port interfaces

Procurement Notes

Verify that the specific application requires extended temperature performance, as this model serves as an upgraded version of the H1036L. Confirm physical footprint compatibility with existing PCB layouts due to the 1.125-inch length dimension. Ensure supply chain sources provide genuine Pulse Electronics components to guarantee signal integrity and reliability standards for critical network infrastructure deployments.

Selection Notes

Select this component when designing systems requiring robust performance across wider thermal environments than standard commercial grade parts allow. The quad-port configuration simplifies board space requirements for multi-port Ethernet designs. Engineers should compare electrical specifications against the baseline H1036L datasheet to confirm that the extended temperature ratings meet specific operational environmental constraints without compromising signal quality.

Part Context

This part belongs to the Pulse Electronics LAN transformer family, specifically engineered for twisted-pair data transmission. It integrates magnetic components necessary for impedance matching and noise suppression in high-speed digital communication links. The module replaces discrete transformer solutions, offering a consolidated approach to meeting IEEE 802.3 compliance requirements for 10/100 Mbps Ethernet networks.

Replacement Considerations

The HX1236T is documented as an extended temperature variant of the H1036L. Substitution requires verification of thermal operating ranges and pinout compatibility. Direct replacement is feasible only if the design accommodates the specific dimensional and electrical characteristics of the HX1236T module.
