FLC1553-45

Overview

The FLC1553-45 is a MIL-STD-1553 interface pulse transformer manufactured by iNRCORE, LLC. Designed for surface mount installation, it features a compact footprint measuring 0.630 inches in length and width (16.00mm x 16.00mm) with a maximum height of 0.159 inches (4.04mm). The component supports specific turn ratios of 1CT:2.5CT and 1CT:1.79CT. It operates within a standard industrial temperature range and carries an MSL rating of 3.

Feature Summary

• Engineered specifically for MIL-STD-1553 bus interface applications requiring precise signal coupling.
• Utilizes a surface mount package design to facilitate automated PCB assembly processes.
• Provides defined turn ratios to ensure proper impedance matching and signal integrity across the data bus.

Applications

• MIL-STD-1553 data bus interface circuits
• Avionics communication systems
• Military-grade electronic equipment

Procurement Notes

Verify the specific datasheet revision when sourcing, as turn ratio specifications may vary between manufacturing batches or revisions. Confirm RoHS compliance status, as some listings indicate non-compliance. Ensure the selected variant matches the required 1CT:2.5CT or 1CT:1.79CT configuration for the target circuit design before finalizing procurement.

Selection Notes

Select this component when a surface mount solution is required for MIL-STD-1553 interfaces. Compare physical dimensions against available PCB real estate, noting the 16.00mm square footprint. Evaluate thermal performance requirements against the specified operating temperature limits. Consider alternative through-hole variants if surface mount capabilities are unavailable for the production line.

Part Context

This part belongs to the FLC series of pulse transformers from iNRCORE, LLC, which focuses on specialized interface components for military and aerospace standards. The series includes various pin configurations and mounting styles tailored for high-reliability environments where strict adherence to MIL-STD-1553 protocols is mandatory for system operation.

Replacement Considerations

FLC1553-5 is a documented substitute offering similar MIL-STD-1553 functionality with different turn ratios (1CT:2.12CT, 1CT:1.5CT). Verify that the alternative's physical dimensions and electrical characteristics align with the existing design constraints before substitution.
