ST and DST PC board transformers use a "split-bobbin" which allows the and secondary to be wound non-concentrically. (i.e., side by side rather than one over the other). This has the advantages of cost saving and superior performance primarily.
Features
- High isolation - 2500V RMS hipot is standard.
- Class B insulation - 130 Celsius.
- Low capacitive coupling-no electro-static shield is necessary.
- Less manufacturing time-no cross-over or primary and secondary leads.
- PC pins-allow direct insertion in PC boards.
- Each transformer is available with single 115V or dual 115/230V primaries, in addition, secondary are split so that they can be series or parallel connected. Variations can be made to meet special needs.
