Completely isolate the capacitor as follows.
・ Between the cathode and the case and between the anode terminal and other circuit paths.
The following misapplication load conditions will cause rapid deterioration of a capacitor’s electrical parameters.
In addition, rapid heating and gas generation within the capacitor can occur, causing the pressure relief vent to operate and resultant leakage
The laminate coating is intended for marking and identification purposes and is not meant to electrically insulate the capacitor.
※
Capacitors with case mounted pressure relief require sufficient clearance to allow for proper pressure relief operation.
The minimum clearance are dependent on capacitor diameters as follows.
(Dia 10mm ～ Dia 16mm : 2mm minimum , Dia 18mm : 3mm minimum)
Avoid locating high voltage or high current wiring or circuit board paths above the pressure relief . Flammable, high temperature gas that
exceeds 100 ﾟ C may be released which could dissolve the wire insulation and ignite.
Avoid circuit board runs under the capacitor, as an electrical short can occur due to an electrolyte leakage.
capacitors. DC bipolar capacitors are not suitable for use in AC circuits.
Standard capacitors are not suitable for use in repeating charge/discharge applications. For charge/ discharge applications, consult us
with your actual application condition.
short periods of time.
Ensure that the sum of the DC voltage and the superimposed AC ripple voltage does not exceed the rated voltage.
Avoid wiring pattern runs, which pass between the mounted capacitor and the circuit board.
DC capacitors have polarity. Verify correct polarity before insertion. For circuits with changing or uncertain polarity, use DC bipolar
Do not apply voltages exceeding the maximum specified rated voltage. Voltages up to the surge voltage rating are acceptable for
Do not apply ripple currents exceeding the maximum specified value. For high ripple current applications, use a capacitor designed for
high ripple currents. In addition, consult us if the applied ripple current is to be higher than the maximum specified value.
Ensure that rated ripple currents that superimposed on low DC bias voltages do not cause reverse voltage conditions.
The circuit resistance can closely approximate the series resistance of the capacitor, causing an imbalance of ripple current loads within
the capacitors. Careful wiring methods can minimize the possible application of an excessive ripple current to a capacitor.
Differences in normal DC leakage current among capacitors can cause voltage imbalances.
The use of voltage divider shunt resistors with consideration to leakage currents can prevent capacitor voltage imbalances.
The land pattern and size shall be decided in consideration of mountability, solderbility and strength.
