Radial Leaded Multilayer Ceramic Capacitors
Goldmax, 300 Series, Conformally Coated,
Z5U Dielectric, 25 – 250 VDC (Commercial Grade)
Overview
KEMET’s Goldmax conformally coated radial leaded
ceramic capacitors in Z5U dielectric feature an 85°C
maximum operating temperature and are considered
“general-purpose.” The Electronics Industries Alliance
(EIA) characterizes Z5U dielectric as a Class III material.
Components of this classification are fixed, ceramic
dielectric capacitors suited for bypass and decoupling or
other applications in which dielectric losses, high insulation
resistance and capacitance stability are not of major
importance. Z5U exhibits a predictable change in capacitance
with respect to time and voltage and displays wide variations
in capacitance with reference to ambient temperature.
Capacitance change is limited to +22%, −56% from +10°C to
+85°C.

Parameters/Characteristics
Regarding Aging Rate: Capacitance measurements (including tolerance) are indexed to a referee time of 48 or 1,000 Hours. Please refer to a part
number specific datasheet for referee time details.
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
if capacitance ≤ 10 µF
120 Hz ±10 Hz and 0.5 ±0.1 V
rms
if capacitance > 10 µF
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."
