TLN1553-3

Overview

The TLN1553-3 is a MIL-STD-1553 interface pulse transformer manufactured by iNRCORE, LLC. It features through-hole mounting and specific turns ratios of 1.25CT:1CT and 1.66CT:1CT. The component measures 0.630 inches in length and width (16.00 mm) with a maximum installed height of 0.159 inches (4.04 mm). It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Designed for MIL-STD-1553 bus interface applications
• Supports dual turns ratio configurations
• Through-hole termination style

Applications

• Military avionics systems
• Aerospace data bus interfaces
• Ruggedized communication equipment

Procurement Notes

Verify the specific turns ratio requirement (1.25CT:1CT or 1.66CT:1CT) against the design schematic before ordering. Confirm that the through-hole package dimensions fit the PCB layout constraints. Ensure the operating temperature range meets the environmental specifications of the final assembly.

Selection Notes

Select this component when a MIL-STD-1553 compliant pulse transformer with through-hole mounting is required. Consider the physical footprint of 16.00 mm x 16.00 mm for board space allocation. Evaluate the thermal performance at the upper limit of 125°C if used in high-temperature environments.

Part Context

This part belongs to the iNRCORE MIL-STD-1553 transformer family, which includes surface mount variants like GL1553-1 and DFLN1553-3. The TLN series specifically addresses through-hole integration needs for legacy or ruggedized military designs requiring robust mechanical attachment.

Replacement Considerations

Direct substitutes include other MIL-STD-1553 through-hole transformers from iNRCORE such as TQ1553-3, provided the electrical parameters and pinout compatibility are verified. Cross-referencing with manufacturer datasheets is essential to ensure equivalent performance characteristics.
