Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
Telecom “Tip and Ring,” X7R Dielectric, 250 VDC
(Commercial Grade)
Overview
KEMET’s 250V DC Tip and Ring MLCCs in X7R dielectric are
designed and rated for telecommunication ringer circuits
where the capacitor is used to block -48V to -52V DC of line
voltage and pass a 16-25 Hz AC signal pulse of 70 Vrms
to 90 Vrms. Serving as an excellent replacement for high
voltage leaded film devices, these smaller surface mount
technology footprints save valuable board space which is
critical when creating new designs.
KEMET Tip and Ring capacitors feature a 125°C
maximum operating temperature and are considered
“temperature stable.” The Electronics Industries Alliance
(EIA) characterizes X7R dielectric as a Class II 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 dielectric
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 are able to withstand today’s higher lead-
free reflow processing temperatures and offer superior high
frequency filtering characteristics and low ESR.

Default packaging is "Bulk Bag". An ordering code C-Spec is not required for "Bulk Bag" packaging.
The terms "Marked" and "Unmarked" pertain to laser marking option of capacitors. All packaging options labeled as "Unmarked" will contain capacitors
that have not been laser marked. Please contact KEMET if you require a laser marked option. For more information see "Capacitor Marking".
2
The 2 mm pitch option allows for double the packaging quantity of capacitors on a given reel size. This option is limited to EIA 0603 (1608 metric) case
size devices. For more information regarding 2 mm pitch option see "Tape & Reel Packaging Information".
Applications
Typical applications include telecommunication ringing circuits, switch mode power supply snubber circuits, high voltage
DC blocking and high voltage coupling. Markets include telephone lines, analog and digital modems, facsimile machines,
wireless base stations, cable and digital video recording set-top boxes, satellite dishes, high voltage power supply, DC/DC
converters, and Ethernet, POS and ATM hardware.
Qualification/Certification
Commercial Grade products are subject to internal qualification. Details regarding test methods and conditions are
referenced in Table 4, Performance & Reliability.
Environmental Compliance
Lead (Pb)-free, RoHS, and REACH compliant without exemptions (excluding SnPb termination finish option).

Insulation Resistance (IR) Minimum Limit at 25°C
Regarding Aging Rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1,000 hours.
DWV is the voltage a capacitor can withstand (survive) for a short period of time. It exceeds the nominal and continuous working voltage of the
capacitor.
3
Capacitance and dissipation factor (DF) measured under the following conditions:
1kHz ± 50Hz and 1.0 ± 0.2 Vrms if capacitance ≤10µF
120Hz ± 10Hz and 0.5 ± 0.1 Vrms if capacitance >10µF
4
To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.
Note: When measuring capacitance it is important to ensure the set voltage level is held constant. The HP4284 & Agilent E4980 have a feature known as
Automatic Level Control (ALC). The ALC feature should be switched to "ON".
