Overview

The HCTSM80305BAL-E is a board-mount power transformer from the Bourns HCT series, designed for high clearance and creepage distance applications. It features a 3:5 turns ratio and an inductance of 300 µH. The secondary current rating is 350 mA peak. Operating temperature range spans from -40°C to +125°C. Dimensions are 12.3 mm length, 10.8 mm width, and 6.5 mm height. It utilizes SMD/SMT termination and is packaged in a reel with AEC-Q200 qualification.

Feature Summary

• High clearance and creepage distance design for enhanced isolation safety
• AEC-Q200 qualified for automotive reliability standards
• Encapsulated construction for environmental protection

Applications

• Automotive power supply circuits
• Isolated DC-DC converter interfaces
• Data interface isolation in harsh environments

Procurement Notes

Verify the specific suffix 'E' against the manufacturer's latest datasheet to confirm compliance with current RoHS directives and material declarations. Ensure the ordering quantity aligns with the standard factory packaging configuration of 2500 units per reel. Confirm that the 3:5 turns ratio matches the target circuit requirements before finalizing procurement.

Selection Notes

Select this component when high voltage isolation barriers are required within compact PCB footprints. The 300 µH inductance supports specific pulse transformer applications requiring defined voltage-time characteristics. Consider the 350 mA secondary rating to ensure adequate current handling for the intended load without saturation under peak conditions.

Part Context

This part belongs to the HCTSM8 series of high clearance transformers manufactured by Bourns Inc. These components are engineered for surface mount technology integration. The series emphasizes robust isolation performance suitable for demanding industrial and automotive electronic systems requiring reliable signal or power transfer across isolation barriers.

Replacement Considerations

Direct substitutes include other HCT series variants with matching 3:5 ratios and similar footprint dimensions. Verify equivalent inductance values and current ratings when considering alternative models from the same manufacturer or different suppliers to maintain circuit performance integrity.
