Who receives the chip capacitor package material bulk material and the overall material package?

<>Well, please take a good look at it with Tan Wan**Oh, good night, letter blind, I want to wake up to sleep, hope, thank you, good luck."

2UF+-10%C4532X7 Tian Murata 0805 0603 0201 1206 0402 etc Murata, Yageo, Taiyo Yuden, TDK, Huaxin And I am a professional collector of these bulk materials and raw materials "MBS1689" SMD capacitor specifications: According to Learn more Murata Murata is producing high-end SMD capacitors for the sake of a better and smarter world. And the collection of these bulk materials "MBS1689" is to test whether the function can achieve high value value and other reasons 1:

Porcelain dielectric capacitors (CT), inexpensive, small capacitance, mainly used in low-frequency circuits. 2: Polyester capacitor (CL), the characteristics and uses are the same as above.

3: Multilayer capacitor (CC), very expensive, small capacity, stable nature. It is generally used in high-frequency circuits.

4: Electrolytic capacitance (CD), large capacity, positive and negative electrodes. It is mainly used for power supply circuits, pulsating circuits.

5: Mica capacitance (CY), withstand voltage (250V-450V), small capacity, very expensive, large volume. It is used in the important parts of the communication machine.

There are also tantalum capacitors (Ca), niobium capacitors (CN), film capacitors, and so on. 2. Capacitive reactance: The capacitor presents a special hindrance effect on alternating current for capacitive reactance, the frequency is inversely proportional to the capacitive reactance, the higher the frequency, the smaller the capacitive reactance, so the capacitor has the characteristics of high frequency and low frequency.

When the frequency is constant, the capacity is inversely proportional to the capacitive reactance, the larger the capacity, the smaller the capacitive reactance, and the smaller the capacitive reactance, the greater the capacitive reactance. When the frequency is 0, the capacitive reactance of the DC capacitance is infinity. Fourth, capacitance nominal method:

The first nominal method for capacitors is the direct standard method: if the nominal is an integer and unitless, it is pronounced as "pf"; If it is marked as a decimal and has no unit, it is pronounced as "uf"; If there are three digits in nominal numbers and no units, the first two digits are significant digits "ab", and the third digit is the magnification "10c"; The imported capacitor has "47ufd", which is "47uf"; Capacitance nominal "3r3", "r" is the decimal point, indicating"; The nominal value is ", which means that "k, j" is the wrong difference; The second is the color mark method, which is the same as the color mark method of resistors. The third special nominal:

109j, 219k, 379k", etc., with 9 "*10-1". 5. Characteristics of capacitance: high frequency, low frequency; AC, DC resistance (refer to capacitive reactance) 6. The role of capacitance:

Filtering, coupling, energy storage 1. Filter capacitor: It is connected between the positive and negative poles of the circuit, and the AC current in the circuit is filtered out by using the characteristics of the capacitor to pass through and separate. A polarized capacitor is usually a negative ground.

2. Coupling capacitor: It is connected between the signal source and the signal processing circuit or two-pole amplifier to isolate the direct current, let the AC or pulsating signal pass through, and make the DC working points of the adjacent amplifier sound against each other. 3. Decoupling capacitor:

It is connected between the positive and negative poles of the circuit to prevent parasitic oscillations caused by the positive feedback path formed by the power supply.
