Hi everyone,
I have a strange problem in measuring NPO MLCC capacitor. I want to measure a NPO capacitor and according to datasheet I should measure the capacitance and DF in 1Mhz,1Vrms condition. but My lcr-meter is GW-instek LCR-819 and it can measure up to 100khz. when I measure C and D in low frequencies i.e 1khz, D value is far from datasheet maximum limit but it is a positive value. when I increase the test frequency up to 40khz, D decreased and is closed to Zero. With further increase of frequency, strangely D value becomes negative.
What is the reason for this phenomenon? how can I measure the right C and D with this LCR (GW-instek LCR-819 100khz)?
thanks
