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."
