The 261C6 is a 17.5 VA plate and filament or bias transformer with a 250V centre-tapped secondary rated 45 mA and a 6.3V filament/auxiliary winding at 1A. Running from a 115 VAC, 60 Hz primary, it is designed for small power or bias supplies, test equipment and preamps, and it is one of the models that can also be used with full wave C.T. rectifiers.
Mechanically it is an economical two hole, channel bracket, chassis mount design with minimum 5" long leads. Ordering-table dimensions are A 3.25 in (83 mm), B 1.65 in (42 mm), C 2.00 in (51 mm) and D 2.81 in (71 mm), with 0.19 in (5 mm) mounting holes (G). The schematic is figure #1.
The 261C6 primary is 115 VAC, 60 Hz, the series standard. It is one of the models (261C6, 261D6, 261E6 and 261G6) that can also be used with full wave C.T. rectifiers. The series provides a convenient 6.3 or 12.6 volt filament/auxiliary winding. The shipping weight is 1 lbs (0.45 kg).
When specifying the 261C6, check its 17.5 VA rating and 250V C.T. @ 45 ma secondary against the plate or bias current your circuit draws, and check the 6.3V @ 1A winding against the total heater or auxiliary load it will carry.
The 261C6 is listed as REACH compliant and RoHS compliant, with UPC 623980272603 and UNSPSC 39121301 for purchasing and inventory records.
