Re: design for new capacitor



Original poster: Ed Phillips <evp@xxxxxxxxxxx>

Hi Ed,

your guess about the 1.55mm is right. To measure the dissipation factor at operating frequency I don't own the equipment. But at 1kHz it's about d=0.006..0.008 (Q=149..120) and at 120Hz it's d=0.003..0.003(Q=165..260), by my LCR meter. Verified the capacitance about being 1.044..1.1nF for a size of the plates of about 25.5 x 14cm copper.

Best regards,  Kurt"

OK on the thickness. That's pretty close to the 0.060 inch stuff we use here (like identical?). Does your LCR meter work at 120 Hz?
