For capacitive divider power supply circuit only contains a few simple components, so its structure is simple and reliable. In this circuit, the most important electronic component is the resistive capacitive buck capacitor. Should the capacitive divider power supply capacitor be an X2 capacitor or a CBB capacitor?
The answer is: X2 capacitors and many CBB capacitors can be used as resistance capacitance step-down capacitors.
X2 safety capacitor specifically designed for capacitive divider power supply
X2 capacitors are mainly used to suppress electromagnetic interference from power sources. Ordinary X2 capacitors cannot be used as resistance capacitance step-down capacitors, otherwise there will be problems such as rapid capacity decay and extremely short service life.
1, If you want to use it in capacitive divider power supply circuits, you must use WFC-A series capacitors specifically designed for resistive capacitive divider.
The X2 safety standard capacitor for resistive capacitive voltage reduction is a type of capacitor used in resistive capacitive voltage reduction circuits, which has excellent electrical and stability performance. This type of capacitor usually uses high-quality dielectric materials and electrode materials, which have the characteristics of high withstand voltage, low loss, good stability, long service life, and comply with safety standards, with safety and reliability.
2. CBB22 capacitor specifically designed for resistive capacitive voltage reduction.
In order to avoid oxidation of the metal coating caused by high voltage communication, the CBB22 capacitor specifically designed for resistive capacitive voltage reduction uses different metal thin films, which can significantly slow down the decay rate of the capacitance value. At the same time, the production process is more complex and must be carried out in a constant temperature and humidity workshop to reduce the water content of the production environment and minimize the adsorption of moisture by the product. The zinc aluminum film capacitor core is immediately sealed after heating up, and the product temperature is increased while being evacuated and cured.
3. MPB box capacitors specifically designed for capacitive divider power supply
This type of capacitor is similar to the CBB22 capacitor, with the same internal capacitor core, except that the MPB capacitor has better performance and longer lifespan.
X2 safety capacitors are mainly divided into two types: one is anti power electromagnetic interference, and the other is resistance capacitance voltage reduction. Today, we will focus on introducing the X2 safety capacitors specifically designed for resistance capacitance voltage reduction.
The X2 safety capacitors used for voltage reduction and the capacitors used for anti-interference, although both are made by winding metalized polypropylene film, still have certain differences in their internal composition,
The main adjustment is to adjust the zinc aluminum ratio of the metal film, and at the same time, the resistance capacitance voltage reduction X2 safety capacitor adopts a double 85 characteristic metalized polypropylene film and epoxy resin cured sealing adhesive.
This is used in resistive capacitive buck circuits, which means that the capacity decay is smaller and the lifespan of the capacitor is longer
Can ordinary anti-interference X2 capacitors be used in resistive capacitive buck circuits? Indeed, there have been some customers who are not familiar with X2 capacitors and directly use ordinary X2 capacitors for anti-interference in resistive capacitive voltage reduction circuits. The result is that their capacity decays quickly. After a few months of use, due to the severe capacity decay of X2 capacitors, the power supply to the resistive capacitive voltage reduction circuit is insufficient, and the electrical appliances cannot be used normally.
What are the characteristics and functions of the X2 capacitor for resistive capacitive voltage reduction? We call the optimized series X2 certified AC safety capacitors for resistance capacitance voltage reduction. They use polymer polypropylene film dielectric, thickened metalized electrodes, fully automatic spray welding process, 94V0 flame-retardant PBT plastic shell, moisture resistant epoxy resin sealing, and CP wire lead out. High voltage resistance, moisture and heat resistance, low capacitance drop, specifically designed for resistive capacitive voltage reduction circuits, such as LED driver modules, electric meters, small household appliances and other low-power electronic consumer products.
Reminder: When choosing X2 capacitors in the future, it is important to clarify whether they are used for anti-interference or resistive capacitive voltage reduction applications. If using resistive capacitive voltage reduction circuits, X2 safety capacitors specifically designed for resistive capacitive voltage reduction must be used, otherwise the circuit is prone to problems.
