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， PH， SH， UJ， capacitor’s capacitance changes with temperature.They are suited for applications

LG， RH， TH， SL

where low-losses and temperature compensating circuits.

X5R、

X7S、

X6S：

X7R、

X5R、X7S、

X6S material is a kind of material has high dielectric constant. The capacitor

※X7R、

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：

capacitor made of this kind of material is considered as ClassⅡ capacitor, whose temperature characteristic

The

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.
