Radial Leaded Multilayer Ceramic Capacitors
High Voltage Goldmax, 300 Series, Conformally Coated,
X7R Dielectric, 500 – 3,000 VDC (Commercial Grade)
Overview
KEMET’s 300 Series High Voltage Goldmax conformally
coated radial leaded ceramic capacitors in X7R dielectric
feature a 125°C maximum operating temperature. The
Electronics Industries Alliance (EIA) characterizes X7R
dielectric as a Class II "temperature stable" material. Com-
ponents of this classification are fixed, ceramic dielectric
capacitors suited for bypass and decoupling applications
or for frequency discriminating circuits where Q and stabil-
ity of capacitance characteristics are not critical. X7R
exhibits a predictable change in capacitance with respect
to time and voltage and boasts a minimal change in capaci-
tance with reference to ambient temperature. Capacitance
change is limited to ±15% from −55°C to +125°C.
These devices offer low leakage current, exhibit low ESR
at high frequencies and find conventional use as snubbers
or filters in applications such as switching power supplies
and in lighting ballasts. Their exceptional performance at
high frequencies has made them a preferred choice of design
engineers worldwide. In addition to their use in power sup-
plies, these capacitors are widely used in industries related to
telecommunications, medical, military, aerospace, semicon-
ductor and test/diagnostic equipment

Parameters/Characteristics
Regarding aging rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1,000 hours.
To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.
Capacitance and dissipation factor (DF) measured under the following conditions:
1 kHz ±50 Hz and 1.0±0.2 V
rms
Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 and Agilent E4980 have a feature known
as Automatic Level Control (ALC). The ALC feature should be switched to "ON."
