HCT80910EAL-E

Overview

The HCT80910EAL-E is a surface-mount pulse transformer from the Bourns HCT8xEAL series, designed for automotive applications. It features a single primary and single secondary winding with a 9:10 turns ratio. Key electrical parameters include an inductance of 160 µH and a maximum isolation voltage of 5.0 kVDC. The component operates within a temperature range of -40°C to +125°C and provides 8.0 mm clearance and creepage distance. Physical dimensions are 14.2 mm in length, 10.6 mm in width, and 8 mm in height.

Feature Summary

• Provides high clearance and creepage distances for enhanced safety isolation
• Designed for automotive-grade reliability and harsh environment operation
• Supports surface mount technology for automated assembly

Applications

• Automotive power supply circuits
• Isolated signal transmission in vehicle electronics
• General purpose pulse transformation in automotive modules

Procurement Notes

Verify the specific suffix EAL against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure the procurement order matches the required AEC-Q200 compliance status if mandated by the design. Confirm that the 5.0 kVDC isolation rating aligns with the system's safety requirements before finalizing the purchase.

Selection Notes

Select this component when high isolation voltage and compact board space are critical constraints. The 9:10 turns ratio suits applications requiring slight voltage step-up or impedance matching in pulse circuits. Consider the 160 µH inductance value for timing requirements. Verify that the SMD footprint fits the PCB layout and that the operating temperature range meets the environmental conditions of the target application.

Part Context

This part belongs to the HCT8xEAL series of high creepage transformers manufactured by Bourns Inc. These components are specifically engineered for automotive electronics, offering robust isolation capabilities in a small surface-mount package. The series supports various input voltages and turns ratios to accommodate different circuit designs while maintaining strict automotive quality standards.

Replacement Considerations

Check for direct substitutes within the HCT8xEAL family with compatible turns ratios and inductance values. Verify that any alternative component maintains the same 5.0 kVDC isolation rating and 8.0 mm clearance/creepage specifications. Ensure the replacement part is also qualified for automotive use and matches the physical footprint for seamless integration.
