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.
Benefits
• −55°C to +125°C operating temperature range
• Lead (Pb)-free, RoHS and REACH compliant
• EIA 0805, 1206, 1210, 1812, 1825, 2220,and
2225 case sizes
• DC voltage rating of 250 V
• Capacitance offerings ranging from 1,000 pF to 6.8 μF
• Available capacitance tolerances of ±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
