Hammond 166E44 6.6VA 44V Center-Tapped Transformer, 150mA

The 166E44 is the largest E-prefix part in this group: a 6.6 VA transformer with a 115 V, 60 Hz single primary and a 44 V C.T. secondary rated 0.15 A. It suits designs needing a 44 V class winding at low current.

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 lists the 166E44 at 2.81 in (71 mm) for dimension A, 1.50 in (38 mm) for B, 1.69 in (43 mm) for C and 2.38 in (60 mm) for D, with a 0.19 in (5 mm) mounting dimension. It ships at 0.7 lbs (0.32 kg).
