SMQT1553-45

Pulse Transformers Overview

The SMQT1553-45 is a pulse transformer manufactured by iNRCORE, LLC, designed for MIL-STD-1553 bus applications. It features a dual turns ratio configuration with primary to secondary ratios of 1CT:2.5CT and 1CT:1.79CT. The component utilizes a surface mount technology (SMT) package, measuring 0.630 inches in length and width (16.00mm x 16.00mm). This device serves as an interface element within the MIL-STD-1553 data bus architecture.

Pulse Transformers Feature Summary

• Dual turns ratio capability supporting 1CT:2.5CT and 1CT:1.79CT configurations
• Surface mount technology (SMT) package design for automated assembly
• Compliance with MIL-STD-1553 bus standards for military data transmission

Pulse Transformers Applications

• MIL-STD-1553 data bus interface circuits
• Military avionics communication systems
• Pulse transformer applications requiring dual ratio isolation

Pulse Transformers Procurement Notes

Verify that the specific part number SMQT1553-45 matches the required dual ratio specifications of 1CT:2.5CT and 1CT:1.79CT. Confirm the surface mount footprint dimensions of 16.00mm x 16.00mm align with the PCB layout. Ensure the manufacturer is identified as iNRCORE, LLC, formerly Pulser, to guarantee compatibility with existing MIL-STD-1553 designs.

Pulse Transformers Selection Notes

Select this component when a dual-ratio pulse transformer is required for MIL-STD-1553 implementations. The SMT package facilitates high-volume manufacturing processes compared to through-hole alternatives. Engineers should verify the electrical parameters against system requirements, specifically the turns ratios, to ensure proper signal integrity and impedance matching within the bus network.

Pulse Transformers Part Context

This component belongs to the SMQ series of pulse transformers from iNRCORE, LLC. The series includes variants such as SMQT1553-10 and SMQC1553-45, which share similar MIL-STD-1553 compliance but differ in package type or ratio specifications. The SMQT1553-45 specifically addresses applications needing dual-ratio functionality in a surface-mount form factor.

Pulse Transformers Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult official iNRCORE cross-reference guides or datasheets for equivalent components with matching dual-ratio specifications and SMT footprints.
