Key Features
50 mm Side-Outlet Housing
Documented -A and -C revisions have a 50 x 50 mm footprint and centrifugal side discharge. The -A drawing shows a 10.0 mm depth, while the -C drawing specifies 10.3 mm.
Revision-Specific Current
The Delta -A series table lists 0.09 A and 1.08 W. The -C revision lists 0.16 A and 1.92 W, so these ratings must not be combined or exchanged.
Distinct Airflow Performance
The -A version is specified at 6500 RPM and 3.88 CFM; the -C version at 5900 RPM and 3.98 CFM. The two revision-specific fan performance curves also differ in static pressure.
Ball Bearing Construction
Delta series drawings identify ball bearings and UL 94 V-0 plastic frame and impeller materials for documented versions of this compact blower family.
Connection and Signal Variants
The documented -C base version uses two power leads, whereas BFB0512HHA-CF00 adds a third speed-sensor wire. Check the complete revision and functional suffix before wiring.
Applications
- Compact industrial electronics ventilation
- Embedded controller and electronic module cooling
- Small power supply enclosure airflow
- Telecommunications equipment thermal management
- Directed airflow across localized electronic components
- Compact computer and networking equipment cooling
- Electronics housings with side-discharge air passages
- Maintenance of compatible 12 VDC centrifugal blower assemblies

Frequently Asked Questions
What is Delta Electronics BFB0512HHA?
BFB0512HHA is a Delta Electronics DC centrifugal blower designation. Documented -A and -C revisions use 12 VDC power and a nominal 50 x 50 mm housing, but their electrical and airflow specifications differ.
Is BFB0512HHA an axial fan or a blower?
It is a centrifugal blower with a side discharge outlet, rather than a conventional square-frame axial fan.
What voltage does BFB0512HHA use?
The Delta -A and -C manufacturer series tables both list 12 VDC. The applicable operating voltage range should be checked against the complete revision.
What are the housing dimensions of BFB0512HHA?
The documented -A series drawing shows a 50 x 50 x 10.0 mm housing, while the -C drawing shows 50 x 50 x 10.3 mm. Compare the actual casing, outlet and mounting points before replacement.
What current does BFB0512HHA require?
The -A manufacturer table lists 0.09 A and the -C table lists 0.16 A. These are different revision ratings, so the fan label or full part number determines the correct value.
What power rating is specified for BFB0512HHA?
Delta lists 1.08 W for revision -A and 1.92 W for revision -C. Check the particular revision rather than assigning one power rating to the unsuffixed designation.
What is the rated speed of BFB0512HHA?
The manufacturer -A series table lists 6500 RPM, while the -C series table lists 5900 RPM. The correct rating depends on the complete revision.
What is the maximum airflow?
Delta lists 3.88 CFM for the -A revision and 3.98 CFM for the -C revision, measured at zero static pressure. Installed airflow depends on system resistance.
What is the maximum static pressure?
The -A series table lists 0.529 inH2O (13.43 mmH2O), whereas -C lists 0.790 inH2O (20.09 mmH2O). Maximum static pressure and maximum free-air flow are separate operating points.
What bearing system and materials are used?
The manufacturer series documentation identifies ball bearings and UL 94 V-0 plastic frame and impeller materials for the documented BFB0512HHA revisions.
Does BFB0512HHA have two or three wires?
The BFB0512HHA-C product listing specifies two lead wires. The separate BFB0512HHA-CF00 model has three leads and a frequency or tachometer signal. Verify any functional suffix and the exact connector before installation.
What should be checked before ordering Delta BFB0512HHA?
Confirm the full BFB0512HHA revision and optional suffix, 12 VDC rating, relevant current, 50 mm housing footprint and depth, outlet and mounting geometry, airflow and static pressure requirements, wire count, connector and any speed-feedback function.
