- CSA certified (File # LR3902) and UL recognized (File #E207860)
- RoHS and REACH compliant
The 160G12 is a low voltage, vertical PC board mount power transformer with a universal dual 115/230V primary rated for 50/60 Hz. Rated 4.4 VA, it is intended for small power supplies and control electronics where one board design may be built for 115V or 230V mains.
The secondary is made of two windings. Connected in series they deliver 12.6V C.T. @ 350ma; connected in parallel they deliver 6.3V @ 700ma. With a 12.6V center-tapped secondary, this part sits at the low-voltage end of the 5 to 120VAC RMS range the series covers.
This 4.4 VA size is non-concentric wound. The 160 series mechanical table gives overall dimensions of 1.69 x 1.25 x 1.45 in (A x B x C), pins of 0.02 x 0.04 in (D) and a second pin style of 0.03 x 0.12 in (F); shipping weight is 0.33 lbs (0.15 kg). The single-primary 115V, 60 Hz version is 161GA12.
Construction uses a split bobbin with low primary-to-secondary coupling, so no electrostatic shield is required. Insulation is Class B (130 degrees C) and hipot tested to 2,000V RMS. The series is CSA certified (File # LR3902) and UL recognized (File #E207860), and this part is listed as RoHS and REACH compliant.
Ideal For
- 4.4 VA PC board mounted power supplies
- Center-tapped or parallel low voltage secondary supply
- Equipment designed for both 115V and 230V mains
- Control and electronic circuit boards needing an isolated AC supply

Frequently Asked Questions
What output does the 160G12 provide?▾
Its two secondary windings give 12.6V C.T. @ 350ma when connected in series, or 6.3V @ 700ma when connected in parallel. The transformer is rated 4.4 VA.
Can the 160G12 run on 230V?▾
Yes. It has a universal dual primary rated 115/230V at 50/60 Hz.
Does it need an electrostatic shield?▾
No. The split bobbin design has low primary-to-secondary coupling, so no electrostatic shield is required.
What certifications and insulation ratings apply?▾
The series is CSA certified (File # LR3902) and UL recognized (File #E207860), with Class B insulation rated 130 degrees C and a hipot of 2,000V RMS. The part is also listed as RoHS and REACH compliant.
How big is the 160G12?▾
The 160 series mechanical table lists overall dimensions of 1.69 x 1.25 x 1.45 in (A x B x C) for the 4.4 VA size. Shipping weight is 0.33 lbs (0.15 kg).
