- 9 VA rating with 120V @ 45 ma secondary
- Filament/auxiliary winding: 12.6V @ 0.3A
- Primary 115 VAC, 60 Hz
- Two hole, channel bracket, chassis mount
- Minimum 5" long leads
- Compact footprint: A 2.81 in (71 mm), B 1.50 in (38 mm), C 1.68 in (43 mm)
- REACH and RoHS compliant
The 262B12 is a 9 VA plate and filament or bias transformer with a 120V secondary rated 45 mA and a 12.6V filament/auxiliary winding at 0.3A. It shares the 262B6 frame size but swaps the heater winding to 12.6V, suiting preamps and small supplies that use 12.6V heaters or an auxiliary rail, on a 115 VAC, 60 Hz primary.
Mechanically it is an economical two hole, channel bracket, chassis mount design with minimum 5" long leads. Ordering-table dimensions are A 2.81 in (71 mm), B 1.50 in (38 mm), C 1.68 in (43 mm) and D 2.38 in (60 mm), with 0.19 in (5 mm) mounting holes (G). The schematic is figure #2.
The 262B12 primary is 115 VAC, 60 Hz, the series standard. The series provides a convenient 6.3 or 12.6 volt filament/auxiliary winding. The shipping weight is 0.6 lbs (0.27 kg).
When specifying the 262B12, check its 9 VA rating and 120V @ 45 ma secondary against the plate or bias current your circuit draws, and check the 12.6V @ 0.3A winding against the total heater or auxiliary load it will carry.
The 262B12 is listed as REACH compliant and RoHS compliant, with UPC 623980273105 and UNSPSC 39121301 for purchasing and inventory records.
