Electrical specifications

Spark Industries leads the way in applications for low power, high voltage spark ignition transformers. Each transformer is made to exact customer specifications with multiple case designs and quick connect terminals to choose from. Our transformers are vacuum encapsulated in a heat resistant molded nylon case with high dielectric epoxy resin assuring excellent insulation properties as well as maintaining close lead location tolerances.


#20 AWG tinned based lead, may be trimmed to any length 0.5'' or less. Various types of high voltage terminals are available.

Body case

Molded black nylon shell.


Internal connections of windings are such that the first high-voltage output pulse will be negative when a charge capacitor with a positive terminal connected to P1 is discharged into primary.

Secondary open circuit output voltage

A 2.2 MFD capacitor charged to 150V is discharged for a minimum time of 1 second at a 60Hz rate into the primary through an SCR. The high voltage output is observed through the oscilloscope and any indication of arching or possible internal ! degradation is cause for rejection.

Electrical parameters

  • Primary resistance: 11 milliohms +/- 10%
  • Primary inductance: 3 microHenries +/- 10%
  • Secondary resistance: 550 Ohms +/- 10%
  • Secondary inductance: 140 milliHenries +/- 10%
