Multi Layer Ceramic Capacitors
■
Introduction
SAMHA’s series of Multi Layer Ceramic(MLC) chip Capacitor is designed to meet a wide variety of
need. Multilayer ceramic chip capacitor are avaliable in both Class
Ⅰ
and Class
Ⅱ
formulations.
Temperature compensation formulations are Class
Ⅰ
and temperature stable and general application
formulations are classified at Class
Ⅱ.
The Class
Ⅰ
multilayer ceramic capacitors are COG with
negligible dependance of electrical properties on temperature, voltage, frequency. The most of
commonly used Class
Ⅱ
dielectric are X7R, X5R and Y5V. The X7R provides intermediate
capacitance values which vary
±15%
over the temperature range of -55℃ to 125℃. The X5R
provides intermediate capacitance value which vary 15% over the temperature range of -55℃to 85℃.
The Y5V provides the highest capacitance value which vary from 22% to-82% over the temperature
range of -30℃to 85℃.
All Class
Ⅱ
capacitors vary in capacitance value under the influence of temperature , operating voltage
and frequency. We offer a complete line of products for both Class
Ⅰ
and Class
Ⅱ.

Multi Layer Ceramic Capacitors
Y5V
APPLICATION -
The Hi-K(Y5V) dielectrics deliver high capacitance density and are ideally suited for
applications where space is at a premium, or as replacement for tanalum capacitors.
Typical applications include uses as by-pass or decoupling elements.
Best performance is obtained at or near room temperature, with low DC bias.
