We shall emphasize the following parameters: - High galvanic insulation between primary winding (control circuit) and secondary winding (power circuit). - Low coupling capacitance between windings. - Low stray inductance. - High transfer capability of unipolar pulses. - Low losses in the magnetic circuit. Applications: Generally, they are used for triggering low, medium and high power thyristors and triacs, as well as for controlling power transistors, used in power electronic circuits. The TI standard series consists of 16 encapsulated models in three case sizes and with one or two secondary windings. By request, we can manufacture special models, according to customer specifications, using other coil formers and core shapes, sizes and types, with some elec-trical features other than than construction or encapsulated, using high permeability E / EF shaped ferrite cores or toroidal ones.
