material introduction |
| * NPO(C0G):The electrical
properties of this kind of capacitor are the most stable
one and have little change with temperature, voltage and
time. They are suited of applications where low-losses
and high stability are required, such as filters,
oscillators, and timing circuits. |
| * X7R:X7R is a kind of material,
which
has high dielectric constant. The capacitance of this kind
of capacitors is higher than that of NPO. These capacitors
are classified as having a semistable temperature characteristic
and used over a wide temperature range, such as
blocking, coupling, bypassing
and frequency discriminating circuit. |
| * Y5V:These capacitors have 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 and measuring
conditions, such
as temperature and voltage, etc. |

¡ñOuter
electrode (termination)
|
| We can provide two kinds of terminations.
One
is Silver. The other is built up of three plating
layers, Silver layer, Nickel
layer and Tin layer. What kind of termination to be chosen
is depended on the soldering method. |
| ¡¡
¡ñPackage
|
| There are two types of package. One is bulk
package, including bulk case and bulk bag. The other is
taping package, including paper tape and embossed tape. |
