What brand of imported MKP capacitor is good

MKP capacitor is the international name of polypropylene metallized film capacitor under the branch of film capacitor, and it is also called CBB capacitor in China, that is, metallized polypropylene film capacitor.

At present, among the international brands, EPCOS (TDK), Kemet, Vishay, Panasonic and so on have a good reputation and a wide range of product models. However, in terms of product delivery and poor cooperation with small customers, it is a common problem of international brands.

The best brand in China is faratronic, I personally think: in the actual quality of the product has surpassed many international brands, but there is still a certain gap in the basic research data of capacitors, the accuracy of technical personnel in the actual selection and application of theories. Among the remaining state-owned brands, there are Foshan Fengming, Sichuan Zhongxing, Taiwan Huarong, etc.

Use a capacitance meter to measure, there is no capacitance meter, use a multimeter to set the gear, touch the two meter pens to the two feet of the capacitor, see the amplitude of the meter pendulum and the speed of the meter return, and then swap the meter pens to measure it again, and the capacitor should be discharged before measurement, and the two feet of the capacitor can be short-circuited with metal objects. The swing size of the watch hand is related to the capacitance of the capacitance, which can be compared with a good capacitance of the same capacitance. If the speed of the watch hand return to the meter is very slow, it is clear that there is leakage of the capacitor, and the slower the speed of the return to the meter, the more serious the leakage is, and it is not difficult to use.

With a multimeter, it is only possible to easily determine whether the capacitor has capacitance or leakage.

It is not enough to judge the withstand voltage of the capacitor.

It is best to do a pressure test on the capacitor (such as using a 400V megohmmeter) If there is no professional thing, it is best to use the exchange method, and the disagreement is determined to use a special capacitor, as long as the capacity and withstand voltage are the same, do not dissipate the original capacitor, solder the new one on it, and power on to see if the induction cooker is good, if it is still not good, it is not a capacitor problem. Send it for repair. If it's good, just powder the bad ones.

Taiwan Yudian film capacitors, good quality, the largest market share.

Other domestic film capacitors are cheap, and most of them use inferior film materials, and the filtering effect is not good. It is not recommended to use domestic production!

MKT is a metallized polyester film capacitor. Metallized polyester film capacitors belong to three categories of capacitors (capacitors can be divided into three categories according to dielectrics: ceramic capacitors, electrolytic capacitors, and film capacitors).

Film capacitors can be divided into metallized polypropylene film capacitors and metallized polyester film capacitors according to their materials.

Film capacitors can be divided into the following according to their applications and specifications

Series of ampere capacitors – commonly used to suppress electromagnetic interference;

Series capacitors - (CBB is often polypropylene film capacitors, CBB21 CBB81 CBB61 CBB65 CBB20, etc.) are used for filtering, cross-line, resonance and other high-frequency, high-power circuits. CBB21 or 81 capacitors are commonly used in LED lamps and LED power supplies, and LEDs have high requirements for temperature and withstand voltage;

Series capacitors - (CL is often polyester film capacitors, including CL21 CL11 CL21X CL233X CL20, etc.), used in various low-power, low-frequency and other circuits.

The European naming of film capacitors will start with MK!

MKP = Metallized polypropylene dielectric capacitance.

MKC = Metallized polycarbonate dielectric capacitance.

MKT = Metallized polyester dielectric capacitance.

MKS = metallized polystyrene capacitors (also polyester dielectric from WIMA, Germany) MKV = metallized oil-immersed AC power capacitors.

mkl = capacitance of metallized paint film dielectric.

MKY = Metallized low-loss polypropylene capacitors.

MKT-P = Metallized polyester paper dielectric capacitance.

MKP crossover capacitors, i.e., metallized polypropylene capacitors.

MKP stands for Metalized Polypropylene Film Capacitor, which means that the aluminum electrode is not a thin film, but an evaporated aluminum foil. Compared with ordinary CBB capacitors, MKP has a high starting point for withstand voltage, low lead-out loss, small internal temperature rise, temperature coefficient of negative capacitance, and excellent flame retardant performance.

It is widely used in high-voltage and high-frequency pulse circuits, S-corrected and counter-path waveforms and displays in televisions, electronic rectification absorption and SCR rectification circuits in lighting circuits. It is used for safety purposes. It is also used when RC is bucked. High cost.

Summary. Hello dear, capacitors are divided into many types, among which capacitors MLC and MKP are two different types, the main difference is in the material and use. 1.

The materials are different: the dielectric of the capacitor MLC (multilayer ceramic capacitor) is made of ceramic, while the dielectric of the MKP capacitor (metallized polypropylene film capacitor) is made of polypropylene film. 2.

Different uses: Capacitor MLC is mainly used in high-frequency circuits, voltage regulators, and analog circuits, and applications that require high precision, low leakage, and high frequency; MKP capacitors, on the other hand, are mainly used in high-power applications, especially in power factor correction circuits used in motors, as well as in some high-sensitivity circuits that require high efficiency, low loss, and high voltage. 3.

The capacitance range is different: the capacitance range of the capacitor MLC is relatively small, generally below a few piofades, while the capacitance range of MKP capacitors is relatively large, which can reach several thousand picofads or even larger.

The dielectric of the MLC (multilayer ceramic capacitor) is made of ceramic, while the dielectric of the MKP capacitor (the big brother of the metallized polypropylene film capacitor) is made of polypropylene film. 2.The number of uses is different from the imitation brother:

Capacitor MLC is mainly used in high-frequency circuits, voltage regulators, analog circuits, and applications that require high precision, low leakage, and high frequency; MKP capacitors, on the other hand, are mainly used in high-power applications, especially in the power factor correction circuits used in motors, as well as in some high-sensitivity circuits where high efficiency, low loss and high voltage are required. 3.The capacity range is different:

MKT is a metallized polyester film capacitor and MKP is a metallized polypropylene film capacitor, both of which are high-quality capacitors, but the latter has lower losses and better performance for distributors. The capacitance capacity of the crossover is accurately calculated according to the horn, inductance, and frequency divider, and the parallel connection is often to get the required capacity, and the size should not be easily changed. If you feel harsh, it may be the result of a mismatch between the crossover and the horn; If it feels good, feel free to use it.
