FPQ1553-8

Overview

The FPQ1553-8 is a dual-stacked pulse transformer designed for MIL-STD-1553 bus applications. It features surface mount installation and operates within a temperature range of -55°C to +130°C. The component has maximum dimensions of 0.630 inches in length and width, with a height of 0.250 inches (6.35 mm). It utilizes a PBC interface standard.

Feature Summary

• Dual stacked construction for compact integration
• Surface mount package type for automated assembly
• Wide operating temperature capability up to +130°C

Applications

• MIL-STD-1553 data bus systems
• Avionics communication interfaces
• Military grade electronic equipment

Procurement Notes

Verify the specific datasheet version from iNRCORE, LLC to confirm RoHS compliance status, as historical records indicate non-compliance for this series. Ensure the ordering suffix matches the required turn ratio configuration. Cross-reference pinout diagrams with the target PCB layout to prevent installation errors during surface mount processing.

Selection Notes

Select this component when a robust, high-temperature pulse transformer is required for MIL-STD-1553 networks. Consider the physical footprint constraints against the 0.630 x 0.630 inch outline. Evaluate thermal management requirements given the +130°C maximum rating compared to lower-grade alternatives.

Part Context

This part belongs to the FPQ1553 series of pulse transformers manufactured by iNRCORE, LLC. The series is specifically engineered for military and aerospace data bus standards. Similar models include the FPQ1553-6 and FPQ1553-10, which share the same form factor but may differ in electrical characteristics or turn ratios.

Replacement Considerations

The FPQ1553-6 and FPQ1553-10 are related parts within the same product family. Verify that any substitute maintains the required MIL-STD-1553 compatibility and physical dimensions. Confirm that the turn ratios of alternative components match the circuit design specifications.
