Radial Leaded Multilayer Ceramic Capacitors
Goldmax, 300 Series, Conformally Coated,
X7R Dielectric, 25 – 250 VDC (Commercial Grade)
Overview
KEMET’s 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. Components of this classification are fixed,
ceramic dielectric capacitors suited for bypass and decoupling
applications or for frequency discriminating circuits where Q
and stability 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 capacitance with
reference to ambient temperature. Capacitance change is limited
to ±15% from −55°C to +125°C.
These devices meets the flame test requirements outlined in
UL Standard 94V–0.
Benefits
• Radial leaded form factor
• Conformally coated
• 0.100", 0.200", 0.250" and 0.400" lead spacing
• −55°C to +125°C operating temperature range
• Lead (Pb)-free, RoHS and REACH compliant
• X7R temperature stable dielectric

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
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."
