Features:Application: can instantly ignite cigarette paper, super small size, DIY electronic lighter, electronic enthusiasts studyInput 3-5v and the secondary high-voltage output is not connected to a high-voltage rectifier diode and capacitor, the output two-stage wire end can generate a purple high-temperature arc with a length of0.8 centimeters and no hum, but the temperature is very high.It can easily light up the cigarette lighter momentarily. Even a very thin wire can be burnt (such as the scene of burning the fine wire in oxygen during the junior high school chemical test, but not as intense as in oxygen).Transformer has been encapsulated with resin, which has high safetyCan work reliably and continuously for a long period of time.(recommended within 1 minute at a time.Pay attention to heat dissipation)Specification:PCB size: 5.4*1.8cm/2.1*0.7inVoltage and current power: DC 3-5V, current 5A, more than 15W. It is recommended to use a 3.7V 18650 lithium battery.Output pulse voltage: 0.5kv-0.8kvWorking frequency: 20khz-25khzArc distance: 5-8 mmSize: 5.4*1.8cm/2.1*0.7inWeight: Approx.12g/0.4ozPackage list:1 set x Arc Igniter Coil Module kit
