224-955-1644Key Features
- 5 VA rating: 12.6V C.T. @ 0.4A with secondaries in series, 6.3V @ 0.8A in parallel
- Universal dual primary: 115 VAC (parallel) or 230 VAC (series), 50/60 Hz
- Dual non-concentrically wound secondaries usable in series, parallel or separately
- Hipot 4,000 V RMS; Class F (155 °C) insulation; no electrostatic shield required
- Low profile split bobbin body, 1.63 x 1.44 x 1.38 in, 0.025 in square pins
- P.C. board mount, industry standard pin spacing, two-hole #4 screw mounting (screws not provided)
- cUL listed series; RoHS and REACH compliant
The 183F12-BULK is the bulk pack part number for the 183F12: the same 5 VA low voltage PCB mount power transformer, listed in the 183 Series ordering table under the Bulk Pack column. It offers a dual 115/230 V primary for 50/60 Hz operation and two secondaries that give 12.6 V C.T. at 0.4 A in series or 6.3 V at 0.8 A in parallel, suited to production builds that place the transformer directly on the circuit board.
Inside, a split bobbin with top shroud keeps the profile low, while the non-concentrically wound secondaries provide low primary-to-secondary coupling without an electrostatic shield. Insulation is Class F, rated 155 °C, and the unit carries a 4,000 V RMS hipot rating.
The series mounting table gives the 5 VA size as 1.63 in long, 1.44 in wide and 1.38 in high, with 0.025 in square pins, two-hole mounting for #4 screws (mounting screws not provided) and a weight of 0.37 lbs.
For 115 V operation the two primaries (pins 1-3 and 4-6) are connected in parallel; for 230 V they are connected in series. Joining secondary pin 9 to pin 10 places the windings in series, and that connection acts as the center tap.
The 183 Series is cUL listed; 183F12-BULK is RoHS and REACH compliant.
Ideal For
- Production PCB assemblies needing a 12.6 V C.T. or 6.3 V AC secondary
- Dual-voltage 115/230 VAC equipment at 50/60 Hz
- Board designs using separate secondary windings

Frequently Asked Questions
What output does the 183F12-BULK provide?▾
It is rated 5 VA: 12.6V C.T. @ 0.4A with the secondaries connected in series, or 6.3V @ 0.8A with them connected in parallel. The windings can also be used separately.
Can it run on both 115 V and 230 V?▾
Yes. It has a universal dual primary for 50/60 Hz. Connect the two primary windings in parallel for 115 VAC or in series for 230 VAC.
Where is the center tap?▾
When the secondaries are connected in series by joining pin 9 to pin 10, that connection acts as the C.T. (center tap).
How big is the 183F12-BULK?▾
The series mounting table lists the 5 VA size at 1.63 in long, 1.44 in wide and 1.38 in high, with 0.025 in square pins, a #4 mounting screw and a weight of 0.37 lbs.
Are mounting screws included?▾
No. The 5 VA size uses two-hole mounting and the manufacturer states mounting screws are not provided; the specified screw is #4.
How does 183F12-BULK differ from 183F12?▾
183F12-BULK is the bulk pack part number that the 183 Series ordering table lists alongside 183F12 for the same 5 VA rating; it carries its own UPC (623980024097).
