According to your requirements,electronic ballast frequency, output power, starting frequency, preheat frequency. For example, operating frequency 20KHZ output power of 20W, the start frequency of 30kHz, preheat frequency 100KHZ, high-frequency inductance value about in 3.5-4mH, inductor core needs to open about 1 mm air gap DC saturation current requirements in 1-1.5 a, you can. This is a key device, If the argument is slightly wrong, it will burn the switch, generally calculated values​​, it tested OK, and then determine the final parameters.
