• Ruggedized communication modules

Procurement Notes

Verify the exact part number suffix against official iNRCORE documentation to ensure correct electrical specifications. Confirm that the surface mount package type matches the design footprint requirements. Check for RoHS compliance status as military components may differ from commercial standards. Ensure the supplier provides traceability documentation required for defense contracts.

Selection Notes

Select this component when a MIL-STD-1553 compliant pulse transformer is required for space-constrained designs. The surface mount form factor facilitates automated assembly processes. Verify that the specified turns ratios align with the system's signal integrity needs. Consider the operating temperature range and humidity sensitivity level during environmental qualification.

Part Context

This component belongs to the iNRCORE MIL-STD-1553 transformer family. These devices are engineered for high-reliability environments typical in defense and aerospace sectors. The series offers various pin configurations and turns ratios to suit different bus topology requirements. The DGL1553-45 represents a specific variant optimized for particular interface characteristics.

Replacement Considerations

Cross-reference with other iNRCORE models such as DGL1553-3 or DGL1553-69 if alternative turns ratios are acceptable. Verify mechanical compatibility before substituting with non-iNRCORE equivalents. Ensure any replacement maintains MIL-STD-1553 compliance.
