Hammond 266J6 6.3VA 6.3V/3.15V 1A Filament Transformer

The 266J6 is a 6.3 VA filament and low-voltage transformer rated 6.3 V at 1 A in series (center-tapped) or 3.15 V at 2 A in parallel. It is a straightforward 6.3 V, 1 A filament winding for equipment fed from 117 or 234 VAC.

The primary accepts 117 or 234 VAC at 50/60 Hz; the 266 Series connection diagrams show the primaries wired in parallel for 117 VAC and in series for 234 VAC. The secondaries can be used as a center tapped secondary (6.3V @ 1A), parallel connected (3.15V @ 2A) or used individually, and the unit is designed for use with all windings engaged. Every unit is hi-pot tested at 2,000V RMS.

Construction is open style with minimum 6" long leads and a dual bobbin design, so no electrostatic shield is required. Class B insulation (130 °C) is used for extra protection, and the design is UL listed as a Class A (105 °C) design.

It provides a full 1 A at 6.3 V, above the 0.6 A 266GB6 and below the 1.2 A 266JB6. The ordering table gives mounting style A, dimensions A 2.82 in (72 mm), B 1.60 in (41 mm), C 1.69 in (43 mm) and D 2.38 in (60 mm), a mounting hole width of 0.19 in (5 mm) and a weight of 0.7 lb (0.32 kg); shipping weight is 0.7 lbs (0.32 kg).

The series is UL listed (# E207860) Type 3AH and CSA certified (209651), and the 266J6 is listed as RoHS and REACH compliant (UPC 623980024844).
