Overview
The FLN1553-3 is a MIL-STD-1553 interface pulse transformer manufactured by iNRCORE, LLC. It features dual secondary winding ratios of 1CT:2.12CT and 1CT:1.5CT, designed for high-speed data transmission in harsh environments. The component utilizes a surface-mount package with dimensions of 0.624 inches in length and width, and a maximum height of 0.250 inches. It operates within a temperature range of -55°C to 130°C and is classified under ECCN EAR99.
Feature Summary
- Designed specifically for MIL-STD-1553 bus interface applications
- Dual secondary winding configurations for flexible circuit integration
- Ruggedized construction suitable for aerospace and defense conditions
Applications
- MIL-STD-1553 data bus interfaces
- Aerospace avionics systems
- Defense communication equipment
Procurement Notes
Verify the specific datasheet version and manufacturer lot traceability before procurement. Confirm that the dual-ratio specification matches the target circuit design requirements. Ensure compliance with project-specific environmental standards given the non-RoHS status. Validate packaging integrity upon receipt to maintain component reliability.
Selection Notes
Select this component when a MIL-STD-1553 interface requires specific impedance matching provided by the 1CT:2.12CT and 1CT:1.5CT ratios. Consider the surface-mount footprint constraints and the wide operating temperature range for deployment in extreme environments. Evaluate thermal management needs relative to the specified maximum height and package size.
Part Context
iNRCORE produces ruggedized magnetic components for mission-critical applications. This part belongs to their MIL-STD-1553 transformer series, which supports high-speed data transmission. The company leverages decades of experience in aerospace and defense sectors to ensure component durability and signal integrity in demanding operational scenarios.
Replacement Considerations
FLN1553-5 and FLN1553-45 are documented substitutes from the same manufacturer. Verify that the alternative part's winding ratios (1CT:2.12CT/1CT:1.5CT vs. others) align with the existing circuit topology before substitution.
