WEE Technology Company Limited - WEE are Capacitors Specialist

WEET would like to share WCD and WCE Series Characteristics of chip smd MLCC multilayer ceramic capacitors:

1. The equivalent series resistance (ESR) is small and the impedance (z) is low.
2. The rated ripple current is large.
3. The varieties and specifications are complete.
4. Small size (withstand voltage 10V).
5. No polarity.

WEET WCD and WCE Series Advantages of chip surface mount MLCC multilayer ceramic capacitors

1. Due to the use of multi-layer dielectric stack structure, the inductance is very low at high frequency, with very low equivalent series resistance, so it can be used in high frequency and very high frequency circuit filtering without opponent.
2. No polarity, can be used in very high ripple circuits or AC circuits.
3. Using in low impedance circuits does not require a large derating.
4. No combustion and explosion during breakdown, high safety.Structure and working principle of chip multilayer ceramic capacitor: MLCC capacitor is simple in structure and consists of ceramic medium, inner electrode metal layer and outer electrode three layers.

The capacity formula of MLCC can be expressed as follows:

C: The capacitance is in F (farad), while the capacitance of MLCC is mainly in PF, NF, and F.
ε: Dielectric constant of insulation between electrodes, in farad / m.
K: Dielectric constant (depending on ceramic type)
A: Conductive area (different product size and printing area)
D: Thickness of dielectric layer (thickness of thin strip)
n: Layers (stack layers)

As we all know, a capacitor is a container that can store electricity. Its basic principle is to use two pieces of metal that are parallel to each other but not in contact with each other. In the middle, air or other materials are used as insulation. One piece of the two pieces of metal is connected to the positive pole of the battery, and the other is connected to the negative pole. The metal piece can store electricity. Compared with the common electrolytic capacitor, MLCC (multilayer ceramic capacitor) can be made into thin sheet (n stack layers are many), so MLCC can greatly improve the capacity of its capacitor under the same volume.
