Description
The Delta BFB04512HHA-9A23 is a compact and powerful 12V DC centrifugal blower fan from Delta Electronics, Inc., measuring 45mm x 45mm x 10mm. Operating at a rated current of 0.26A (3.12W), this fan is engineered to provide high static pressure, making it ideal for cooling in confined spaces or pushing air through restrictive components like heat sinks, ducts, or 3D printer hot ends. It achieves a high rotational speed of 6500 RPM, delivering approximately 3.5 CFM of focused airflow with a noise level of 35.5 dBA. Equipped with double ball bearings, it ensures a long operational life of 50,000 hours. The fan typically utilizes a 3-wire connector, often including a speed signal (tachometer) output for monitoring, ensuring reliable performance and precise control in various thermal management applications.
