SMD aluminum electrolytic capacitor -Smart home

SMD aluminum electrolytic capacitor can withstand large pulsating currents in the circuit, have large capacity, and large capacity errors. They are needed in many low-frequency bypass and signal coupling circuits. The difference with the smd capacitor is that the smd aluminum electrolytic capacitor has positive and negative poles, and the stability is better than that of the plug-in. Pingshang Technology's own brand is better at serving high-quality products!

  The product features and functions of SMD aluminum electrolytic capacitor are:

(1) The working medium of the smd aluminum electrolytic capacitor is to generate a very thin layer of aluminum oxide (Al2O3) on the surface of the aluminum foil by anodizing. This oxide dielectric layer and the anode of the capacitor are combined to form a complete system. The two are interdependent and cannot be independent of each other; what we usually call a capacitor, its electrodes and dielectric are independent of each other.

(2) The anode of the smd aluminum electrolytic capacitor is an aluminum foil with an Al2O3 dielectric layer on the surface. The cathode is not the negative foil we are used to thinking, but the capacitor's electrolyte.

(3) The negative foil plays the role of electrical extraction in the electrolytic capacitor, because the electrolyte as the cathode of the electrolytic capacitor cannot be directly connected to the external circuit, and an electrical path must be formed through another metal electrode and other parts of the circuit.

((4) The anode aluminum foil and cathode aluminum foil of smd aluminum electrolytic capacitor are usually corroded aluminum foil, and the actual surface area is much larger than its apparent surface area. This is also one of the reasons why aluminum electrolytic capacitor usually have large capacitance. Aluminum foil with many fine etched holes usually needs liquid electrolyte to make more effective use of its actual electrode area.

(5) Since the dielectric oxide film of the smd aluminum electrolytic capacitor is obtained by anodizing, and its thickness is proportional to the voltage applied by the anodizing, in principle, the thickness of the dielectric layer of the aluminum electrolytic capacitor can be Control artificially and accurately.
