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.
Benefits
• –55°C to +125°C operating temperature range
• Lead (Pb)-free, RoHS and REACH compliant
• EIA 0603, 0805, 1206, 1210, 1812, 1825, 2220 and 2225
case sizes
• DC voltage rating of 250 V
• Capacitance offerings ranging from 180 pF to .47 μF
• Available capacitance tolerances of ±5%, ±10% and ±20%
• Non-polar device, minimizing installation concerns
• 100% pure matte tin-plated termination finish that allows
for excellent solderability
• SnPb termination finish option available upon request
(5% Pb minimum)
• Flexible termination option available upon request

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.
