PCB MOUNTING MINIATURE
A range of high quality, industry standard, audio frequency transformers, enclosed in ABS
cases.
Specifically designed for direct printed circuit board mounting on a 0.1 inch grid.
Each transformer is constructed with dual windings on the primary and secondary providing a
wide range of impedance matching ratios to suit many input, interstage and output
applications.
A foil screen is provided between the primary and secondary windings and the transformers
are rated at 100mW at 300 Hz and 1mW at 30 Hz (less than 1% T.H.D.)
An optional Mu-metal screening can, is available if required. P/N A262CAN)
