The 165V12 is a 252 VA chassis-mount transformer providing 12.6 V center-tapped RMS at 20 A from a 115 VAC, 60 Hz single primary. The 12.6 V C.T. rating makes it relevant to designers working with 12.6 V filament or low-voltage circuits that need up to 20 A.
Construction follows the 165 Series design: an open-style, four-hole frame for chassis mounting, a dual bobbin winding arrangement that needs no electrostatic shield, and Class B insulation rated 130 degrees C. Connections are made through minimum 6 in long leads or copper tabs with holes, and every unit is Hi-Pot tested at 2,000 V RMS.
Its short description reads FIL RECT 250VA 115 12.6CT, while the part page lists the exact 252 VA rating. The frame measures 3.75 in (95 mm) at A, 3.63 in (92 mm) at B, 3.25 in (83 mm) at E and 4.00 in (102 mm) at F, with a 0.22 in x 0.56 in mounting slot, and it ships at 5.5 lbs (2.49 kg).
