The 166C12 is a 0.63 VA low-voltage transformer with a 115 V, 60 Hz single primary and a secondary rated 6.3/12.6 V C.T. at .1/.05 A. Its short description, POWER TX 115VAC - 6.3V@.1A, points to 6.3 V use in small indicator, filament and control circuits.
As a 166 Series part it uses an economical single-primary design, an open-style channel bracket for two-hole chassis mounting, and minimum 6 in long leads. The dual bobbin construction means no electrostatic shield is required. Windings use Class B insulation (130 degrees C) for extra protection, although the design is UL listed as a Class A (105 degrees C) design, and each unit is Hi-Pot tested at 2,000 V RMS.
The ordering table gives the 166C12 an overall size of 2.06 in (52 mm) at A, 1.25 in (32 mm) at B and 1.19 in (30 mm) at C, with dimension D at 1.75 in (44 mm) and a 0.19 in (5 mm) mounting dimension. It ships at 0.3 lbs (0.14 kg).
