Report No.: 17029429 001
TRF No. IEC60065K
Construction:
Concentric windings on T375J type bobbin or similar phenolic type. Two layers insulation tape separating
between each primary winding as functional insulation. Three layers insulation tape separating between
primary and secondary winding as reinforced insulation. Primary and secondary winding leads exit directly
through integral flanges in bobbin and secured soldered to the pins moulded into the bobbin.
