The 229A16 is a 6 VA low-profile power transformer from the 229 Series for printed circuit board mounting. A universal dual primary accepts 115/230V at 50/60 Hz, and the secondary is rated 16V C.T. @ 350ma in series or 8V @ 700ma in parallel, making it a flexible choice for electronics designers building one board for multiple mains voltages.
The 229A16 delivers 16 V centre-tapped at 350 mA, or 8 V at 700 mA in parallel, with a listed shipping weight of 0.35 lbs (0.16 kg).
The design uses a dual split bobbin with semi-toroidal construction, giving low primary to secondary coupling, balanced windings and low EMF radiation, so no electrostatic shield is required. Insulation is Class B (130 degrees C) and the insulation system is hipot rated at 1,750V RMS.
Mechanical data for the 6 VA size: A 1.56 in, B 1.88 in, C 0.85 in, D and D1 0.38 in, E 1.60 in, with 1.00 in PC board spacing and 0.02 x 0.04 in pins. Regulation is listed at 30% for this size. Shipping weight is 0.35 lbs (0.16 kg).
The 229 Series is C UL US recognized under UL file E207860, and the 229A16 is RoHS and REACH compliant.

It has a universal dual primary for 115/230V at 50/60 Hz.
With the secondary windings in series it delivers 16V C.T. @ 350ma; in parallel it delivers 8V @ 700ma, for a 6 VA rating.
It is a low-profile PC board mount part. The 6 VA mechanical data lists A 1.56 in, B 1.88 in, C 0.85 in, D and D1 0.38 in, E 1.60 in, with 1.00 in PC board spacing and 0.02 x 0.04 in pins.
Yes. The 229 Series is C UL US recognized under UL file E207860.
No. The semi-toroidal, dual split bobbin design gives low primary to secondary coupling and balanced windings, so no electrostatic shield is required.
Regulation for the 6 VA size is listed at 30%.
