RELIABILITY TEST CONDITION
NO ITEMS TEST CONDITION PERFORMANCE
1 RATED DC VOLTAGE -55℃ ~ +85℃ 2.5∼35V
2 CAPACITANCE
MEASURING FREQUENCY : 120±12Hz
MEASURING VOLTAGE : 0.5Vrms + 0.5∼2V DC
MEASURING CIRCUITS : EQUIVALENT SERIES
CIRCUIT
CAPACITANCE RANGE
0.1∼330㎌
TOLERANCE ON CAP.

MEASUREMENT SHALL BE MADE UNDER THE
SAME CONDITIONS AS THOSE GIVEN FOR THE
MEASUREMENT OF CAPACITANCE.
4 LEAKAGE CURRENT
THE RATED DC VOLTAGE SHALL BE APPLIED
TO TERMINALS ACROSS THE TEST CAPACITOR
Cx, BY THE METHOD AS SHOWN BELOW. THE
LEAKAGE CURRENT SHALL THEN BE
MEASURED AFTER CHARGE FOR 5 MIN.
