Frequently Asked Questions
What is Delta Electronics TFC1212DE?
TFC1212DE is a Delta Electronics DC brushless axial cooling fan designation. The manufacturer CSA certification record identifies a 12 VDC, 3900 mA model, and suppliers commonly list 120 x 120 x 38 mm assemblies.
What is the rated voltage?
Delta's CSA record specifies 12 VDC. A complete-model manufacturer approval confirming the exact operating voltage range was not established.
What is the input current?
The manufacturer certification record identifies 3900 mA, equivalent to 3.90 A. Multiple complete-model supplier listings also specify 3.90 A. Confirm the electrical rating on the supplied fan label.
What is the electrical power?
Multiplying 12 VDC by 3.90 A gives 46.80 W. This is an electrical calculation based on the listed current and should not be interpreted as a separately verified typical running-power specification.
What are the dimensions?
Multiple suppliers specify 120 x 120 x 38 mm. Confirm the mounting-hole pattern, fan depth, airflow direction and cable clearance before replacing an installed cooling fan.
What is the rotational speed of TFC1212DE?
The TFC1212DE-SP07 PWM version is listed at 5500 RPM. Other unsuffixed TFC1212DE listings quote approximately 4800 RPM or different values. An exact-model Delta engineering specification resolving those differences was not established.
What is the maximum airflow?
The SP07 variant is advertised at approximately 252 CFM, while some other sellers report around 190 CFM for TFC1212DE. Verify the complete fan configuration before using either airflow value in an engineering calculation.
What is the maximum static pressure?
Some PWM-version sellers report 35.88 mmH₂O, approximately 1.41 inH₂O. This figure has not been independently verified against a matching Delta approval specification for the unsuffixed TFC1212DE.
What are the bearing and noise specifications?
The TFC1212DE-SP07 is described as a ball bearing fan producing approximately 66 dB(A). Other suppliers identify dual ball bearings. Acoustic figures for every possible unsuffixed TFC1212DE configuration were not independently established.
Does TFC1212DE support four-wire PWM control?
The TFC1212DE-SP07 and TFC1212DE-PWM configurations are marketed with four wires, PWM speed control and tachometer feedback. The manufacturer CSA record also identifies standard, F00 and R00 configurations, so signal functions depend on the exact model suffix.
Is TFC1212DE the same as PFC1212DE-F00?
No. PFC1212DE-F00 is a separate Delta model with its own manufacturer-published electrical and performance specifications. Similar seller-listed airflow values do not establish electrical, mechanical or control-signal interchangeability.
What should be checked before ordering Delta TFC1212DE?
Confirm the complete TFC1212DE marking and any suffix, 12 VDC supply, 3.90 A certification current, 120 x 120 x 38 mm frame, mounting dimensions, bearing requirements, connector style, wire count, PWM and feedback functions, fan speed, airflow, noise limits and compatibility with the installed equipment.
