- 5 VA rating: 36V C.T. @ 0.14A with secondaries in series, 18V @ 0.28A 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 body 1.63 x 1.44 x 1.38 in (41.4 x 36.6 x 35.1 mm), 0.025 in square pins
- P.C. board mount, industry standard pin spacing, two-hole #4 screw mounting (screws not provided)
- Series listed cUL; part drawing cites cURus, CE and TUV; RoHS and REACH compliant
The 183F36 is the highest-voltage 5 VA model in the 183 Series, delivering 36 V C.T. at 0.14 A with the secondaries in series or 18 V at 0.28 A in parallel. It mounts on a printed circuit board and has a universal dual primary for 115 V or 230 V at 50/60 Hz, which the manufacturer's drawing describes as intended for worldwide use.
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.
Per the 183F36 drawing, the body measures 1.63 in (41.4 mm) long, 1.44 in (36.6 mm) wide and 1.38 in (35.1 mm) high, with 0.025 in (0.6 mm) pins, #4 mounting screws (not provided) in a two-hole pattern, and a weight of 0.37 lbs (0.17 kg).
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. Pin numbers are not marked on the unit; a paint dot always identifies the secondary side (pins 12-7).
The 183 Series is cUL listed, and the drawing for this part cites agency listings of cURus, CE and TUV; 183F36 is RoHS and REACH compliant.
Ideal For
- 36 V C.T. or 18 V AC supply on a printed circuit board
- Products for worldwide 115 VAC or 230 VAC mains
- Low-current circuits using the two secondaries separately

Frequently Asked Questions
What output does the 183F36 provide?▾
It is rated 5 VA: 36V C.T. @ 0.14A with the secondaries connected in series, or 18V @ 0.28A 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).
What are the dimensions of the 183F36?▾
The drawing gives L 1.63 in (41.4 mm), W 1.44 in (36.6 mm) and H 1.38 in (35.1 mm), with 0.025 in (0.6 mm) pins, a #4 screw type and a weight of 0.37 lbs (0.17 kg).
How do I identify the pins?▾
Pin numbers are not printed on the unit. Look for the paint dot, which is always on the secondary side (pins 12-7).
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.
