Pulse Transformers Procurement Notes

Verify the specific manufacturing date code against project requirements as this part may be classified as obsolete or end-of-life by the manufacturer. Confirm that the surface mount footprint dimensions match the existing PCB layout. Ensure compatibility with reflow soldering profiles specified in the official datasheet to maintain component integrity during assembly.

Pulse Transformers Selection Notes

Select this component when designing for T1/E1 or ISDN-Pri digital telephony interfaces requiring dual-channel isolation. The 1200 µH inductance value supports the necessary impedance matching for these standards. Consider the 0.7 Ohm DC resistance for power loss calculations in low-voltage signal paths. Verify that the operating temperature range meets the environmental conditions of the target application.

Pulse Transformers Part Context

This transformer belongs to Pulse Electronics' portfolio of audio and signal transformers specifically engineered for telecommunications. It falls under the category of modules designed for digital subscriber line and traditional telephony infrastructure. The product is intended for use in network interface units and central office equipment where reliable signal transmission over copper pairs is required.

Pulse Transformers Replacement Considerations

Public sources indicate the T1093 is marked as obsolete. Potential substitutes include other T1/E1 dual transformers from Pulse Electronics such as the T1144NLT, though pinout and inductance values must be verified against the original design specifications before implementation.
