Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)

Telecom “Tip and Ring” X7R Dielectric, 250 VDC

(Commercial Grade)

Overview

KEMET’s 250 V DC Tip and Ring MLCCs in X7R dielectric are

designed and rated for telecommunication ringer circuits where

the capacitor is used to block -48 V to -52 V 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.

See Insulation Resistance Limit Table

(Rated voltage applied for 120 ±5 seconds @ 25°C)

Parameters/Characteristics

Regarding aging rate: Capacitance measurements (including tolerance) are indexed to a referee time of 1,000 hours.

To obtain IR limit, divide MΩ-µF value by the capacitance and compare to GΩ limit. Select the lower of the two limits.

Capacitance and dissipation factor (DF) measured under the following conditions:

1 kHz ±50 Hz and 1.0 ±0.2 Vrms if capacitance ≤ 10 µF

120 Hz ±10 Hz and 0.5 ±0.1 Vrms if capacitance >10 µF

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."
