Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
Telecom Tip & Ring, X7R Dielectric, 250 VDC
(Commercial Grade)
Overview
The KEMET 250 VDC Tip and Ring MLCCs in X7R dielectric
are designed and rated for telecommunication ringer
circuits, where the capacitor is used to block –48 to –52
VDC 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.
The 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."

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."
Qualification/Certification
Commercial grade products are subject to internal qualification. Details regarding test methods and conditions are
referenced in Table 4 , Performance and Reliability.

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:
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
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 and Agilent E4980 have a feature known
as Automatic Level Control (ALC). The ALC feature should be switched to "ON."
