The WEET WCA high-voltage ceramic chip capacitor is a round chip capacitor with ceramic material as the medium.The shell is ceramic for insulation.
One of the main characteristics of high-voltage ceramic capacitor is that it has high withstand voltage, and the voltage is generally greater than 1KV
The high-voltage ceramic capacitor has the voltage of 2KV, 3KV and 4KV, Often used in high-pressure situations, Up to 30KV
In the porcelain capacitor, the voltage below DC50V is generally called low voltage, DC100v ~ 500V is medium high voltage,
DC1000V ~ 6000V and is high voltage, and the voltage above DC6000V is ultra high voltage
Safety Y capacitor is also a high-voltage ceramic chip capacitor
The WEET WCA ceramic chip capacitor can be divided into class I porcelain, class II porcelain and class III porcelain. Class I porcelain, NPO, has good temperature, frequency and voltage characteristics. Because the dielectric constant is not high, the capacity is not large; class II porcelain, X7R comes next, has good temperature and voltage characteristics; class III porcelain has high dielectric constant, so the capacity can be large, but the temperature and voltage characteristics are not good, High voltage ceramic capacitor is generally small in size.
In addition, after breakdown, the ceramic capacitors tend to be in a short circuit state(this is its weakness) and after the film capacitor fails, it is generally in an open circuit state.The capacitance of high-voltage ceramic depends on the occasion of use, and the typical function can eliminate high-frequency interference.High voltage ceramic capacitors used in high power and high voltage fields are required to be small, high voltage withstand and good frequency characteristics.In recent years, with the progress of materials, electrodes and manufacturing technology, the development of high-voltage ceramic chip capacitor has made great progress and has been widely used. High voltage ceramic capacitor has become one of the indispensable components of high power and high voltage electronic products.

Generally speaking, the WEET Chip capacitor refers to MLCC, that is, multilayer ceramic capacitors, also known as chip capacitor or SMD capacitor. Conventional chip capacitors are divided into COG (NPO), X7R, Y5V according to materials. According to British standard, there are 12 types of pin package: 0201, 0402, 0603, 0805, 1206, 1210, 1812, 1825, 2010, 2225, 3012, 3035.
0201, 0402, 0603, 0805 and 1206 are WEET chip capacitors with common package sizes, and the capacity range is generally 0.5pf ~ 1uF.
1210, 1812, 1825, 2010, 2225, 3012, 3035 are large-scale WEET chip capacitors, with a capacity range of 1uF ~ 100uF.
WEE Technology Multilayer ceramic capacitor (MLCC) is composed of parallel ceramic materials and electrode materials.
WEET MLCC products have high dimensional accuracy, which is convenient for high-efficiency assembly of automatic SMT machine; the end electrode is three-layer electrode, which is suitable for wave soldering and reflow soldering; the dielectric body and the surface are the same material, with small environmental impact, high insulation resistance and high reliability; it contains various temperature characteristic media from cog to Y5V, which is suitable for communication, computer, household appliances, instruments and other common electronic equipment.
WEET WCD and WCE Series Characteristics and Advantages of Chip SMD MLCC Multilayer Ceramic Capacitor
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.
