T1114NL

Pulse Transformers Overview

The T1114NL is a surface-mount pulse transformer manufactured by Pulse Electronics, designed for T1/E1 and ISDN-Pri applications. It features a dual-channel configuration with a turns ratio of 1:2CT for the transmitter and 1CT:2 for the receiver. The component has an inductance of 1.2mH per channel and operates within a temperature range of -40°C to +85°C. Physical dimensions are 28.58mm in length, 12.32mm in width, and 5.84mm in height. It is supplied in tube packaging.

Pulse Transformers Feature Summary

• Supports T1/E1 quad and ISDN-Pri signal transmission standards
• Provides galvanic isolation between transmitter and receiver circuits
• Surface mount construction for automated PCB assembly

Pulse Transformers Applications

• T1/E1 line interface units
• ISDN Primary Rate Interface equipment
• Telecommunications network termination systems

Pulse Transformers Procurement Notes

Verify the specific package type upon ordering, as the T1114NLT variant utilizes reel or cut tape packaging while the T1114NL typically uses tubes. Confirm moisture sensitivity level (MSL 4) requirements for your manufacturing process. Ensure the 1:2CT and 1CT:2 winding configurations match your circuit design needs before finalizing procurement.

Pulse Transformers Selection Notes

Select this component when designing for T1/E1 or ISDN-Pri interfaces requiring surface-mount integration. Compare physical footprint constraints against the 28.58mm x 12.32mm dimensions. Verify that the 1.2mH inductance meets your impedance matching requirements. Consider the T1114NLT if reel packaging is preferred over tubes for high-volume production lines.

Pulse Transformers Part Context

This part belongs to Pulse Electronics' portfolio of telecommunications transformers. It serves as a critical isolation component in digital telephony infrastructure. The product line supports various T-carrier and E-carrier standards, ensuring compatibility with legacy and modern telecom hardware requiring robust signal integrity and electrical isolation.

Pulse Transformers Replacement Considerations

The T1114NLT is documented as a parameter-equivalent substitute. Verify that the packaging difference (tube vs. reel/cut tape) does not impact your assembly process. No other cross-model substitutes are confirmed in the provided documentation.
