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.
It is recommended to set the test frequency to 1 kHz for multi layer ceramic capacitor 10 ìF
