DGLN1553-3

Overview

The DGLN1553-3 is a MIL-STD-1553 interface pulse transformer manufactured by iNRCORE, LLC. It features a surface mount installation type with dimensions of 0.624 inches in length and width (15.86mm x 15.86mm) and a maximum height of 0.250 inches (6.35mm). The component supports dual turns ratios of 1.25CT:1CT and 1.66CT:1CT. It operates within a temperature range of -55°C to 130°C and holds a Moisture Sensitivity Level (MSL) rating of 3 (168 hours).

Feature Summary

• Designed for MIL-STD-1553 bus interface applications.
• Provides dual primary-to-secondary turns ratio options.
• Constructed for ruggedized military and aerospace environments.
• Utilizes a compact surface mount package format.

Applications

• MIL-STD-1553 data bus transceiver interfaces
• Military avionics communication systems
• Aerospace electronic control units

Procurement Notes

Verify the specific turns ratio requirement against the datasheet, as the series offers multiple variants. Confirm that the operating environment remains within the specified -55°C to 130°C range. Ensure proper handling procedures are followed due to the MSL 3 classification. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a MIL-STD-1553 compliant pulse transformer is required for space-constrained designs. The dual-ratio capability allows flexibility in impedance matching for different bus configurations. Consider the surface mount form factor for automated assembly processes. Validate thermal performance under peak load conditions to ensure reliability in high-temperature operational scenarios.

Part Context

This part belongs to the DGLN1553 series of signal transformers from iNRCORE, LLC. The series includes various models such as DGLN1553-2 and DGLN1553-7, which share similar MIL-STD-1553 interface functionalities but differ in specific electrical parameters and physical dimensions. These components are engineered for high-reliability applications in defense and aerospace sectors.

Replacement Considerations

Direct substitutes include other parts within the iNRCORE DGLN1553 series, such as DGLN1553-2 or DGLN1553-7, provided the turns ratios match the circuit design. Cross-manufacturer replacements require careful verification of electrical characteristics and mechanical footprint compatibility.
