High Voltage Ceramic Capacitors ! Caution
Continued from the preceding page.
<DEF Series>
1. Operating Voltage
The frequency of the applied sine wave voltage should be
less than 100kHz. The applied voltage should be less
than the value shown in the figure below. For non-sine
wave that includes a harmonic frequency, please contact
our sales representatives or product engineers.
The temperature of the surface of the capacitor:
10000
below the upper limit of its rated operating temperature
(6300)
to 10pF
12 to 22pF
27 to 47pF
range (including self-heating).
The capacitor can be applied at a maximum of
6.3kVp-p at 100kHz when the lamp is turned on.

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. When the capacitor is used in a high-
frequency current, pulse current or similar current, it may
self-generate heat due to dielectric loss.
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.)
3. Fail-Safe
When the capacitor is broken, failure may result in a short
circuit. Be sure to provide an appropriate fail-safe
function like a fuse on your product if failure could result
in an electric shock, fire or fume.
