Types of Dielectric Material and Capacitor
※HIGH
FREQUENCY TYPE: The capacitor of this kind dielectric material is considered as ClassⅠcapacitor, including
high frequency COG、COH capacitor and temperature compensating capacitor such as HG, LG, PH, RH,SH, TH, UJ,
SL. The electrical properties of COG、COH capacitor are the most stable one and change invariablly with temperature,
voltage and time. They are suited for applications where low-losses and high-stability are required, HG,

and temperature compensating circuits.
※X7R、X5R:X7R、X5R
material is a kind of material has high dielectric constant. The capacitor made of this kind
material is considered as Class
Ⅱ
capacitor whose capacitance is higher than that of class
Ⅰ.
These capacitors are
classified as having a semi-stable temperature characteristic and used over a wide temperature range, such in these
kinds of circuits, DC-blocking, decoupling, bypassing, frequency discriminating etc.
※Y5V:The
capacitor made of this kind of material is the highest dielectric constant of all ceramic capacitors. They are
used over a moderate temperature range in application where high capacitance is required because of its unstable
temperature coefficient, but where moderate losses and capacitance changes can be tolerated. Its capacitance and
dissipation factors are sensible to measuring conditions, such as temperature and voltage, etc.
※Z5U:The
capacitor made of this kind of material is considered as ClassⅡ capacitor, whose temperature characteristic
is between that of X7R and Y5V. The capacitance of this kind of capacitor is unstable and sensible to temperature and
voltage. Ideally suited for bypassing and decoupling application circuits operating with low DC bias in the environment
approaches to room temperature.
