ATE-1637

Overview

The ATE-1637 is a T1/CEPT/ISDN Primary Filter Module manufactured by Allied Components International. It functions as a pulse transformer designed for telecommunications applications, specifically supporting T1, E1, CEPT, and ISDN-Pri standards. The component features surface mount (SMD/SMT) termination style and operates within a frequency range starting at 1 MHz. It provides an isolation voltage of 1.5 kV, ensuring electrical separation in network interfaces.

Feature Summary

• Designed for T1, E1, CEPT, and ISDN primary rate interface filtering
• Surface mount construction for automated assembly integration
• Provides high-voltage isolation between circuit sections

Applications

• T1 line interface circuits
• E1 network equipment
• ISDN primary rate adapters

Procurement Notes

Verify the manufacturer designation as Allied Components International when sourcing. Confirm the specific datasheet version matches the required T1/CEPT/ISDN filter specifications. Ensure the surface mount package type aligns with the PCB layout design. Cross-reference the isolation voltage rating against system safety requirements before procurement.

Selection Notes

Select this module for applications requiring standardized T1 or ISDN primary filtering. Consider the surface mount form factor for compact board designs. Verify compatibility with the target network protocol, whether T1, E1, or CEPT. Ensure the operating frequency range meets the signal integrity needs of the communication link.

Part Context

This component belongs to the Allied Components International series of telecommunications filters. Similar models include the ATE-1638S, which supports T1/E1/CEPT/ISDN-Pri filtering. These modules are categorized under pulse transformers and LAN transformers, serving critical roles in digital telecommunication infrastructure and network interface cards.

Replacement Considerations

The ATE-1638S is a documented substitute part number from the same manufacturer, offering support for T1/E1/CEPT/ISDN-Pri filtering. Verify pinout compatibility and mechanical dimensions before substitution. Ensure the replacement meets the same isolation voltage and frequency range requirements.
