DHS Series !Caution and Notice
Caution
1. Operating voltage
When DC-rated capacitors are to be used in AC or ripple
current circuits, be sure to maintain the Vp-p value of the
applied voltage or the Vo-p which contains DC bias within
the rated voltage range. When the voltage is applied to
the circuit, starting or stopping may generate irregular
voltage for a transit period because of resonance or
switching. Be sure to use a capacitor with a rated voltage
range that includes these irregular voltages.

2. Operating temperature and self-generated heat
Keep the surface temperature of a capacitor below the
upper limit of its rated operating temperature range. Be
sure to take into account the heat generated by the
capacitor itself.
4. Operating and storage environment
The insulating coating of capacitors does not form a
perfect seal; therefore, do not use or store capacitors in a
corrosive atmosphere, especially where chloride gas,
sulfide gas, acid, alkali, salt or the like are present. And
avoid exposure to moisture.
When the capacitor is used in a high-frequency current,
pulse current or similar current, it may self-generate heat
due to dielectric loss. The applied voltage load should be
such that the capacitor's self-generated heat is within
10°C at an atmosphere temperature of 25°C.
Before cleaning, bonding, or molding this product, verify
that these processes do not affect product quality by
testing the performance of a cleaned, bonded or molded
product in the intended equipment.
When measuring, use a thermocouple of small thermal
capacity-K of ø0.1mm in conditions where the capacitor
is not affected by radiant heat from other components or
surrounding ambient fluctuations.
Store the capacitors where the temperature and relative
humidity do not exceed –10 to 40°C and 15 to 85%. Use
capacitors within 6 months.
5. Vibration and impact
Excessive heat may lead to deterioration of the
capacitor's characteristics and reliability. (Never attempt
to perform measurement with the cooling fan running.
Otherwise, accurate measurement cannot be ensured.)
Do not expose a capacitor to excessive shock or vibration
during use.
Failure to follow the above cautions may result, worst
case, in a short circuit and cause fuming or partial
dispersion when the product is used.
3. Installation
Installation torque should not exceed the torque strength
values in "Specifications and Test Methods".
Do not use a screw with a thread depth greater than
specified.
Avoid installation in which any bending torque is applied
