A. Because the capacity of electrolytic capacitors is much larger than that of general fixed capacitors, the appropriate range should be selected for different capacities when measuring. In general, the capacitance between 1 ~ 47μF can be measured by R × 1k, and larger than 47μF can be measured by R × 100.
A、因為電解電容的容量較一般固定電容大得多,所以,測量時,應針對不同容量選用合適的量程。一般情況下,1~47μF間的電容,可用R×1k擋測量,大於47μF的電容可用R×100擋測量。

B. Connect the red meter to the negative pole and the black meter to the positive pole. At the moment of contacting, the pointer deflects to the right largely (for the same resistance, the larger the capacity, the larger the swing), and then gradually turn left until it stops at a certain point, which is  the forward leakage resistance that is slightly larger than the reverse leakage resistance. The leakage resistance should generally be above hundreds kΩ, otherwise, it will not work properly. In the test, if there is no charging phenomenon in the forward direction and the reverse direction, that is the needle does not move, which means that the capacity disappears or the internal circuit is broken. If the resistance measured is small or zero, it indicates that the capacitor is large leakage resistance or has been broken and damaged, cannot be use any more.
B、將萬用表紅表筆接負極,黑表筆接正極,在剛接觸的瞬間,萬用表指針即向右偏轉較大偏度(對於同一電阻擋,容量越大,擺幅越大),接着逐漸向左迴轉,直到停在某一位置。此時的阻值便是電解電容的正向漏電阻,此值略大於反向漏電阻。電解電容的漏電阻一般應在幾百kΩ以上,否則,將不能正常工作。在測試中,若正向、反向均無充電的現象,即錶針不動,則說明容量消失或內部斷路;如果所測阻值很小或為零,說明電容漏電大或已擊穿損壞,不能再使用。

C. For the electrolytic capacitor whose signs are unknown, it can be discriminated by using the above method. Frist, measure the leakage resistance at randomly and remember its swing. Then, exchange the test leads to measure a resistance. In two measurements, the large resistance is the forward connection, that is the black meter is connected to the positive pole and the red one is connected to the negative pole.
C、對於正、負極標誌不明的電解電容器,可利用上述測量漏電阻的方法加以判別。即先任意測一下漏電阻,記住其大小,然後交換表筆再測出一個阻值。兩次測量中阻值大的那一次便是正向接法,即黑表筆接的是正極,紅表筆接的是負極。

D. Via the multimeter to charge the electrolytic capacitor from the positive and the reverse side, the capacity can be estimated according to the magnitude of the swinging.
D、使用萬用表電阻擋,採用給電解電容進行正、反向充電的方法,根據指針向右擺動幅度的大小,可估測出電解電容的容量。

The fundamental electrical properties of multilayer ceramic capacitors are as follows:

Polarity: Multilayer ceramic capacitors are not polar, and may be used with DC voltage applied in either direction.

Rated Voltage: This term refers to the maximum con tinuous DC working voltage permissible across the entire operating temperature range. Multilayer ceramic capacitors are not extremely sensitive to voltage, and brief applications of voltage above rated will not result in immediate failure. However, reliability will be reduced by exposure to sustained voltages above rated.

Like all other practical capacitors, multilayer ceramic capacitors also have resistance and inductance. A simplified schematic for the equivalent circuit is shown in Figure 1. Other significant electrical characteristics resulting from these additional properties are as follows:

Impedance: Since the parallel resistance (Rp) normally very high, the total impedance of the capacitor is :

The variation of a capacitor’s impedance with frequency determines its effectiveness in many applications.

Ceramic capacitors have a variety of different ceramic dielectrics as the basis of the capacitor. Ceramic dielectrics are made from a variety of forms of ceramic dielectric. The exact formulas of the different ceramics used in ceramic capacitors vary from one manufacturer to another but common compounds include titanium dioxide, strontium titanate, and barium titanate.

The actual performance of the ceramic capacitors is highly dependent upon the dielectric used. Using modern dielectrics, very high values are available, but it is also necessary to check parameters such as the temperature coefficient and tolerance. Different levels of performance are often governed by the dielectric used, and therefore it is necessary to choose the type of dielectric in the ceramic capacitor.

Kingtronics www.kingtronics.com  produce and sell Ceramic Capacitors all types. Multilayer Ceramic Capacitors are available in four series in Kingtronics: AKT Series Axial Lead, Axial MLCC Capacitors(Multilayer Ceramic Capacitors), MKT Series Radial MLCC Capacitors(Multilayer Ceramic Capacitors), LKT Series Chip MLCC.

Rectifiers find a use in detection of amplitude modulated radio signals. The signal may be amplified before detection, but if un-amplified, a very low voltage drop diode must be used. When using a rectifier for demodulation the capacitor and load resistance must be carefully matched. Too low a capacitance will result in the high frequency carrier passing to the output and too high will result in the capacitor just charging and staying charged.

Kingtronics’s fast recovery rectifier diodes are very popular in the overseas market, According to the rectifier’ s application , Our Kingtronics managing ordinary rectifier diodes, ultra-fast rectifier diodes. In our Kingtronics website www.kingtronics.com ,we have detailed PDF about all kinds of diodes & rectifiers.

About

Kingtronics International Company was established in 1995 located in Dongguan City of China to handle all sales & marketing for factories located in Chengdu, Sichuan and Zhaoqing, Guangdong, China. In 1990, we established the first factory to produce trimming potentiometer and in 1999 we built up new factory in Zhao Qing, Guangdong. Now with around 850 workers, Kingtronics produce trimming potentiometers, dipped tantalum capacitors, multilayer ceramic capacitors, and diode & bridge rectifier. We sell good quality under our brand Kingtronics, and Kt, King, Kingtronics are our three trademarks. All our products are RoHS compliant, and our bridge rectifier have UL approval.
