HV Spark Coil
These compact Ignition Coils can step up from 12V to over 20kV. The auto ignition coil is a type of autotransformer designed to be driven with current pulses.
You can drive these coils using an oscillating relay, or a transistor based oscillator like our Adjustable Pulse Generator. The connections to the primary coil can be made using mini spade connectors
This makes them very simple to use with high voltage projects such as lifters, Jacobs ladders, or plasma globes.
These coils have a efficient laminated iron cores so they can be driven with either low or high frequency pulses. At low frequency the coil can produce long sparks to grounded objects, and at high frequency it will produce hot arcs that can be drawn out like in a Jacobs ladder.

Dimensions: 185mm x 45mm x 27mm
