An ignition apparatus (10) includes a suppression device (74) comprising a suppression winding (76) that is in series with the secondary winding (30) and is further located outside of a magnetic circuit. The suppression winding (76) is made from the same wire as used in the secondary winding (30) and is wound on a reduced diameter portion of a secondary winding spool (28). A carbon resistor (84) is disposed in series with the suppression winding (76) in another embodiment. Nickel wire (86) may be substituted for the suppression winding and carbon resistor (84) in order to obtain both inductance and resistance characteristics for the suppression device (74).
