HCTSM80308BAL-E

Overview

The HCTSM80308BAL-E is a board-mount pulse transformer from Bourns, designed for isolation and data interface applications. It features a 3:8 turns ratio and an inductance of 300 µH. The component supports peak secondary currents of 350 mA with voltage ranges of 3.3-5V and 3.3-15V. It has an ET value of 11 V/µs and operates within a temperature range of -40°C to +125°C. Dimensions are 12.3 mm x 10.8 mm x 6.5 mm. It is AEC-Q200 qualified and RoHS compliant.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• High clearance and creepage distance design
• Encapsulated construction for isolation and data interfaces

Applications

• Automotive electronic systems requiring isolated power or data transmission
• Industrial control circuits needing high-reliability signal isolation
• Telecommunication equipment utilizing encapsulated pulse transformers

Procurement Notes

Verify the specific suffix 'E' indicates RoHS compliance when ordering. Confirm that the 3:8 turns ratio matches the target circuit requirements. Ensure the PCB footprint accommodates the 12.3 mm x 10.8 mm dimensions. Check lead times as this item may be produced to order rather than held in general stock.

Selection Notes

Select this component when high insulation integrity is required due to its high clearance and creepage distances. The 300 µH inductance and 350 mA peak current rating suit moderate power isolation needs. Consider the surface mount package for automated assembly processes in compact designs.

Part Context

This part belongs to the HCTSM8 series of high-clearance transformers by Bourns. It is distinct from the HCT8 series which offers different inductance values like 160 µH. The HCTSM8 series specifically targets applications demanding robust isolation barriers in space-constrained environments.

Replacement Considerations

The HCTSM80308BAL-E1 is listed as a parameter-equivalent substitute. Verify mechanical and electrical compatibility before substitution. No other direct cross-model replacements are confirmed in public documentation.
