FLC1553-1

Overview

The FLC1553-1 is a pulse transformer designed for MIL-STD-1553 bus interface applications. It features a surface mount package with dimensions of 0.630 inches by 0.630 inches (16.00mm x 16.00mm) and a maximum seated height of 0.159 inches (4.04mm). The component supports turn ratios of 1CT:1CT and 1CT:0.707CT. It operates within a temperature range of -55°C to +125°C and is classified as non-compliant with RoHS standards.

Feature Summary

• Designed specifically for MIL-STD-1553 bus interface requirements
• Supports dual turn ratio configurations for flexible circuit integration
• Constructed for ruggedized surface mount installation

Applications

• MIL-STD-1553 bus transceiver interfaces
• Military avionics data bus systems
• Ruggedized communication equipment

Procurement Notes

Verify the specific datasheet version for the FLC1553-1, as iNRCORE products often carry RoHS non-compliance status due to military specifications. Confirm that the surface mount footprint matches the design layout, noting the 16.00mm x 16.00mm body size. Ensure the selected turn ratio variant aligns with the system's impedance matching requirements before finalizing procurement.

Selection Notes

Select this component when a MIL-STD-1553 compliant pulse transformer is required for surface mount assembly. The FLC1553-1 offers dual turn ratio options to accommodate different bus line impedances. Consider the operating temperature range and non-RoHS status if the application involves strict environmental or commercial compliance regulations beyond military standards.

Part Context

This part belongs to iNRCORE's family of MIL-STD-1553 interface transformers. Similar models include the GL1553-1 and SMQC1553-7, which share the same interface standard but may differ in package type, turn ratios, or mounting style. These components are engineered for high-reliability digital signal isolation in defense and aerospace environments.

Replacement Considerations

Direct substitutes include other iNRCORE MIL-STD-1553 pulse transformers such as the GL1553-1. Verify pinout compatibility and physical dimensions before substitution. Alternative manufacturers may offer functionally equivalent parts, but military qualification data must be reviewed separately.
