2010年1月3日 · The 2sc2078 is an RF transistor. In the datasheet of the BD243C there is no maximum frequency given.

2015年7月25日 · Hi guys! Here is a pulsed LC oscillator based on 555 IC. It generates about 800Vpp pulsed sinusoidal waveform which may be used in powering up Fluorescence tubes. It may also be used in wireless transmission of power. Greetings

2010年1月7日 · hello friends, can anyone tell me the exact match for the transistor 2sc2078 ? i gonnna use it in a amplifier circuit at 13 mhz. and also make me clear with my doubt ! my doubt is , can i opt for a binacular core instead of two ferrite …

2021年7月27日 · I agree that each long wire is an inductor that barely passes the high frequency. The long wires also have capacitance coupling between them and to ground. The antique MJE3055 power transistor has low current gain and also works poorly at the high frequency.
