Characteristics of ceramic capacitors
① Since the dielectric material of the capacitor is Taowa, it has good heat resistance and is not easy to age.
②Porcelain dielectric capacitors can withstand acid, alkali and salt corrosion, and have good corrosion resistance.
③ The low-frequency ceramic material has a large dielectric constant, so the low-frequency ceramic capacitor has a small volume and a large capacity.
④Good insulation performance, can be made into high-voltage capacitors.
⑤ The loss tangent of high-frequency ceramic materials has a very small relationship with frequency, so high-frequency monitoring capacitors can be used in high-frequency circuits.
⑥The price is cheap, the raw materials are abundant, and it is suitable for mass production.
⑦Mengjie capacitors have small capacitance and low mechanical strength.
There are many varieties of ceramic dielectric capacitors. According to the dielectric material, they can be divided into high dielectric constant capacitors and low dielectric constant capacitors; according to the operating frequency, they can be divided into high-frequency ceramic capacitors and low-frequency dielectric capacitors; according to the working voltage, they can be further divided into High-voltage ceramic capacitors and low-voltage ceramic capacitors. The shape and structure of ceramic capacitors are also diverse, and the common ones are wafer-shaped, tube-shaped, through-core, cylindrical and laminated.
