BA60951CS

Overview

The BA60951CS is a flyback power transformer manufactured by Bourns Inc., designed for surface mount technology (SMD/SMT) PCB integration. It features dual primary and dual secondary windings with a primary voltage rating of 7 V to 24 V and a secondary voltage rating of 15 V. The component provides a power rating of 2.25 W, a secondary current rating of 150 mA, and an inductance of 25 uH. It operates at a frequency of 120 kHz with a maximum operating temperature of +155°C and a minimum of -40°C. Physical dimensions are 13.6 mm length, 10.5 mm width, and 5.97 mm height.

Feature Summary

• Dual primary and dual secondary winding configuration for flexible circuit integration
• Surface mount design optimized for automated PCB assembly processes
• High thermal stability supporting operation up to +155°C

Applications

• Switched-mode power supply (SMPS) circuits
• Flyback converter topologies
• Low-power AC/DC adapter designs

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Bourns or authorized distributors before procurement. Confirm that the 120 kHz operating frequency aligns with your controller specifications. Ensure PCB footprint matches the 13.6 x 10.5 mm SMD package dimensions. Check isolation voltage requirements against the 2.5 kV specification provided in technical documentation.

Selection Notes

Select this component when a compact flyback transformer is required for low-power applications up to 2.25 W. The dual winding structure supports various input ranges from 7 V to 24 V. Consider the 150 mA secondary current limit and 15 V output requirement. The high-temperature rating makes it suitable for environments requiring robust thermal performance within standard SMPS constraints.
