Overview
The DFL1553-1 is a MIL-STD-1553 interface transformer manufactured by iNRCORE, LLC. It features a dual-channel design with available turn ratios of 1CT:1CT and 1CT:0.707CT. The component has a maximum DC resistance of 3 ohms. Physical dimensions are 23.62 mm in length, 16 mm in width, and 3.94 mm in height. It utilizes surface mount termination for integration into circuit boards.
Feature Summary
- Designed specifically for MIL-STD-1553 bus interface applications
- Dual-channel configuration supporting multiple signal paths
- Surface mount technology for automated assembly processes
Applications
- Military avionics data bus systems
- Aerospace communication interfaces
- Ruggedized electronic equipment requiring MIL-STD compliance
Procurement Notes
Verify the specific turn ratio variant required for the design, as both 1CT:1CT and 1CT:0.707CT configurations exist within this part number family. Confirm that the surface mount package dimensions align with the PCB footprint constraints. Ensure the supplier provides documentation confirming compliance with MIL-STD-1553 standards for the intended application environment.
Selection Notes
Select this component when a compact, dual-channel solution is needed for MIL-STD-1553 signaling. Compare the physical size against available board space. Evaluate the DC resistance specifications against signal integrity requirements. Consider the surface mount orientation relative to other components on the assembly.
Part Context
This device belongs to iNRCORE's line of ruggedized audio and signal transformers. It is engineered for harsh environments where reliability is critical. The product series includes various pinout and ratio options to accommodate different system architectures while maintaining consistent performance characteristics across the module.
Replacement Considerations
Check for direct substitutes such as the DFLN1553-1 or GL1553-1 if pin compatibility differs. Verify that alternative models support the same MIL-STD-1553 electrical parameters. Ensure the replacement maintains the required form factor and mounting style for the existing hardware layout.
