N O T E
1
Q value is the reciprocal of DF.
2
This specification is based on the measurement performed at the test socket.
3
DUT and test leads need to be properly shielded to GUARD if necessary.
4
Cx = Counts of displayed C value, e.g. C = 88.88 µF then Cx = 8888.
N O T E
It is recommended to set the test frequency to 1 kHz for multi layer ceramic capacitor 10 ìF
and below.
