LEADED CAPACITORS, NETWORKS & HV CAPACITORS
HIGH VOLTAGE/POWER CAPACITORS
3.5kV to 42kV
DCT & DAT Series
These units are designed for such
applications as high frequency
heating equipment to which high
frequency power or high DC or AC
voltage is applied.
FEATURES
s Small size and high capacitance
s Linear and reversible temperature
characteristics
s Very high “Q” and high insulation
resistance from low to high frequencies
s No performance deterioration after
extended life – excellent humidity and
thermal resistance
s Low series inductance and operable
to high frequencies
s Large power capability in small
packages due to low dielectric
loss when high voltage and high
frequency is applied
APPLICATIONS
s Oscillator matching, coupling or
bypass circuits in broadcast or radio
communication equipment, etc.
s Oscillators, coupling circuit or bypass
capacitors in industrial or medical high
frequency appliances such as high
frequency heating equipments or
ultra-sonic instruments.
s Coupling capacitors for transmission
lines and carrier frequency equipment.

SPECIFICATIONS
Capacitance
The capacitance shall remain within the specified tolerance
when measured at 20°C and at 1MHz ± 100kHz with not
more than 5Vrms. (For capacitors with the ZM characteristic,
the measurement is performed at 1kHz ± 100Hz with not
more than 5Vrms.)
Q and tan ␦
UJ, CH, AH, SL
When operating the capacitors at an ambient temperature of
50°C or more, reduce the load power according to Fig. 1 and
the formula given below:
WLT: K1 x W
WLT: Permissible power at an ambient temperature
T°C (kVA)
W : Rated power capacity (kVA)
K1 : Load power reduction factor
The values of Q shall be as shown below when measured
at 20°C and at 1MHz ± 100kHz with not more than 5Vrms.

Withstanding Voltage
There shall be now damage when the test voltage
(peak value/ Ȉȉ2 ) of 100kHz to 1MHz is applied
between terminals for 1min. ± 5 sec.
When subjecting the capacitors to forced-air cooling,
avoid cooling locally; this may lead to uneven temperature
distribution in the capacitors, resulting in ruptured capacitors.

may cause corona discharge or flashover.
Temperature Coefficient
The changes in capacitance shall be within the ranges
shown below over a temperature range of +20°C to +85°C,
with the value at 20°C being the reference.

NOTICE
Avoid subjecting the capacitors to undue shock such as
dropping, etc., as it may cause cracking to the ceramic.
Avoid carrying the capacitors mounted because
unnecessary vibration or shock can lead to degradation
in terminal strength and cracking of the ceramic.
DataSheet4UAv.cooidminstalling the capacitors with only one side mounted
as it may lead to degradation in terminal strength.
PRECAUTION
When using the capacitors, strictly observe the rated voltage,
current and power. Continued overload use may result in
the following failures:
Ceramic cracking
Flashover takes place over the surface, leading to a
fire hazard.
The ceramic may produce abnormal heat (200°C or more)
if the ceramic incurs feedthrough damage with resultant
overcurrent flowing through.
