Mwen pa t 'gen nenpòt ki pi bon kondansateur RF nan men ou, ak olye pou yo kòmann-nan lou metal devwa kondansateur rekouvèr mika nan dola plizyè chak, mwen deside fè pwòp mwen. Isit la se yon egzanp, yo montre ansanm ak yon tranzistò TO-92 pou konparezon gwosè. Mwen itilize 0.5mm fèy kòb kwiv mete pou electrodes an ekstèn, 0.1mm kòb kwiv mete papye pou yon sèl la andedan, e li te koupe mika soti nan TO-247 izolan.

I didn't have any better RF capacitors on hand, and instead of ordering heavy duty metal clad mica capacitors at several dollars each, I decided to make my own. Here is one example, shown alongside a TO-92 transistor for size comparison. I used 0.5mm copper sheet for the external electrode, 0.1mm copper foil for the inside one, and mica cut from TO-247 insulators.
