I measured dissipation factor at 100 kHz with my DE5000 LCR meter. Green YYT varicap dissipation factor 0.002 Brown plastic varicap dissipation factor 0.008 100 pF 2 kV capacitor dissipation factor 0.000 NP0 47 pF capacitor dissipation factor 0.000 NP0 33 pF capacitor dissipation factor 0.000 so reasonably good performance for YYT varicap
Good seller, I suggest. Fast, accurate and good quality.
