passive electronic component

  With the rapid growth of electronic information technology, the update speed of digital electronic products is getting faster and faster. The sales of consumer electronic products such as flat-panel TVs, notebook computers, digital cameras and other products continue to grow, which drives the growth of the capacitor industry. Today, the Aillen   capacitor manufacturer will introduce the types of capacitors. A. Aluminum electrolytic capacitors A capacitor with a thin oxide film as the medium is wound by absorbent paper impregnated with paste electrolyte between two aluminum foils. Because the oxide film has unidirectional conductivity, the electrolytic capacitor has polarity. It has the following characteristics: 1. Large capacity, able to withstand larger pulsating current. 2. The capacity error is large, the leakage current is large, and the ordinary one is not suitable for application under high frequency and low temperature, and it is not suitable to use the frequency above 25KHz.

Aillen is a professional  capacitor manufacturer  with many years of industry experience and has solved many problems for our customers. Welcome to consult us. As an indispensable part of the components of our daily electrified products, capacitors are widely used in direct current isolation, coupling, bypass, filtering, tuning loops, energy conversion, control circuits, etc. Most of the reasons for the damage of electrical products may be due to the damage of the capacitor, so how should we measure the quality of the capacitor? 1. Pointer multimeter resistance file to check the quality of electrolytic capacitors This method is suitable for capacitors with relatively low voltage resistance, such as electrolytic capacitors below 6V or 10V. First, set the pointer multimeter to the resistance position, the position is R*1K, and then connect the red test lead to the negative pole of the capacitor and the black test lead to the positive pole. When the pointer of the multimeter changes while

  In a DC circuit, a capacitor is equivalent to an open circuit. A capacitor is a component that can store charge and is also one of the most commonly used electronic components. In the circuit, the capacitor has the following functions: 1. Coupling: The capacitor used in the coupling circuit is called the coupling capacitor. This type of capacitor circuit is widely used in the  resistance-capacitance  coupling amplifier and other capacitive coupling circuits to isolate the direct current from the alternating current. 2. Filtering: The capacitor used in the filter circuit is called the filter capacitor. This capacitor circuit is used in power supply filtering and various filter circuits. The filter capacitor will remove the signal in a certain frequency band from the total signal. 3. Decoupling: The capacitor used in the decoupling circuit is called the decoupling capacitor. This capacitor circuit is used in the DC voltage supply circuit of the multi-stage amplifier. The decoupling cap
