Overview
The DKG1553-45 is a MIL-STD-1553 interface pulse transformer manufactured by iNRCORE, LLC. It features a through-hole mounting type with dimensions of 17.15 x 10.16 x 4.7 mm. The component supports dual channels with specific pin configurations: 1-3:15-14 / 6-8:11-10 and 1-3:16-13 / 6-8:12-9. Turn ratios are specified as 1:1.79 and 1:2.5. The device is classified under Passives Transformers, specifically Pulse/Datacom Transformers.
Feature Summary
- Designed for MIL-STD-1553 bus interface applications
- Dual channel configuration for signal transmission
- Through-hole technology (THT) installation
Applications
- MIL-STD-1553B data bus systems
- Military avionics communication interfaces
- Ruggedized electronic equipment requiring pulse isolation
Procurement Notes
Verify the specific turn ratio requirement (1:1.79 or 1:2.5) against the design schematic to ensure compatibility. Confirm that the through-hole footprint matches the PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the manufacturer standard lead time aligns with production schedules.
Selection Notes
Select this component when a dual-channel MIL-STD-1553 interface transformer is required. Compare the physical dimensions of 17.15 x 10.16 x 4.7 mm against available board space. Evaluate the pinout configuration for ease of integration into existing designs. Consider the active lifecycle status for long-term supply availability.
Part Context
This part belongs to the iNRCORE MIL-STD-1553 transformer family, which includes variants like DKG1553-75 and DGL1553-45. These components are categorized as COTS (Commercial Off-The-Shelf) passives designed for robust performance in defense and aerospace sectors. The series provides standardized solutions for serial data bus isolation.
Replacement Considerations
Direct substitutes within the same series include DKG1553-75. Verify pin compatibility and electrical parameters before swapping. Generic replacements may not match the specific MIL-STD-1553 timing requirements.
