Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
Telecom “Tip and Ring,” X7R Dielectric, 250VDC
(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 Components, Assemblies & Materials
Association (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.
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.
