DTL1553-5

Overview

The DTL1553-5 is a pulse transformer designed for MIL-STD-1553 interface applications. It features through-hole mounting and specific turns ratios of 1CT:2.12CT and 1CT:1.5CT. The component measures 0.630 inches in length and width, with a maximum installation height of 0.159 inches. It is classified as an interface transformer suitable for military standards.

Feature Summary

• Designed specifically for MIL-STD-1553 bus interface requirements
• Utilizes through-hole mounting technology for board integration
• Provides defined primary-to-secondary turns ratios for signal coupling

Applications

• MIL-STD-1553 data bus interface circuits
• Military avionics communication systems
• Ruggedized electronic equipment requiring standard bus isolation

Procurement Notes

Verify the specific datasheet version and mechanical drawings prior to ordering. Confirm that the through-hole package dimensions align with the target PCB layout. Ensure compliance with RoHS exemption status if required by project specifications. Cross-reference the manufacturer part number to avoid confusion with surface mount variants.

Selection Notes

Select this component when MIL-STD-1553 compatibility is mandatory and through-hole assembly is preferred over surface mount options. Consider the physical footprint constraints regarding the 0.630-inch square outline. Evaluate the specific turns ratio requirements against the system's impedance matching needs. Verify availability of the specific suffix variant within the product line.

Part Context

This part belongs to the iNRCORE pulse transformer series tailored for military communication standards. It serves as a critical isolation component within the MIL-STD-1553 network architecture. The design supports reliable signal transmission across isolated segments of the bus system.

Replacement Considerations

DTL1553-1 is a documented low-profile dual through-hole substitute within the same family.
