OSG5TS7334A is a surface mount transformer by Opto Supply Group. It is a 5W, SMD step down transformer, with a single-phase, full-wave, center-tap primary and dual secondary winding for outputting dual 33V AC at 0.43A. With an external shield and a core material of E-type ferrite, the transformer provides excellent isolation and insulation from the primary to secondary windings. It has a 4.7K insulation resistance, a working frequency of 50/60Hz, and a maximum temperature of 105°C. The transformer measures 17.2 x 12.7 x 10.2mm, making it a great choice for applications where space is limited.
