HCTSM80102AAL-E

Overview

The Bourns HCTSM80102AAL-E is a surface-mount power transformer designed for board mounting applications. It features a 1:2 turns ratio and supports input voltages of 3.3-5V with output capabilities of 3.3-15V. The secondary current rating is 350 mA peak, and the primary inductance is 250 µH. The component operates within a temperature range of -40°C to +125°C and meets AEC-Q200 qualification standards. Physical dimensions are 12.3 mm in length, 10.8 mm in width, and 6.5 mm in height.

Feature Summary

High clearance and creepage distance design for enhanced isolation safety
AEC-Q200 qualified for automotive reliability requirements
Encapsulated pulse transformer construction for durability

Applications

Automotive power supply circuits
Isolated DC-DC converter interfaces
Signal isolation in high-voltage environments

Procurement Notes

Verify RoHS compliance status and specific packaging options such as cut tape or reel quantities before ordering. Confirm that the AEC-Q200 qualification aligns with project automotive standards. Ensure PCB footprint matches the specified 12.3 mm by 10.8 mm dimensions. Check for any lead-free soldering requirements compatible with the SMD/SMT termination type.

Selection Notes

Select this component when high isolation voltage and compact surface-mount form factors are required. The 1:2 turns ratio suits step-up or isolated signal transmission needs. Consider the 350 mA peak current limit for load matching. The wide operating temperature range supports harsh environmental conditions typical in automotive and industrial sectors.
