Aluminum electrolytic capacitors (also known as aluminum electrolytic capacitors or electrolytic capacitors) are polarized capacitors whose anode electrode is an oxidized aluminum pseudo-particle. The electrolyte acts as a second electrode. Aluminum electrolytic capacitors are electrically polarized and cannot be replaced by other capacitors. Aluminum electrolytic capacitors are suitable for situations with high requirements for capacitance, volume or cost, and are widely used in electronic circuits.

ELXY160ETD681MJ20S is an aluminum electrolytic capacitor, the size of which is 16mm X 11mm X 5.5mm. The rated capacitance of ELXY160ETD681MJ20S is 680μF, rated voltage is 6.3V and rated frequency is 4KHz. Actually, its capacitance range is within 680±20%, so the maximum values should not exceed 816μF. ELXY160ETD681MJ20S is more suitable for filtering, decoupling and integrating, charging/discharging energy storage and other applications.

In order to work properly, ELXY160ETD681MJ20S requires continuous reverse polarity protection. This will prevent any potential damage to the product, as the capacitor will experience catastrophic failure if reverse bias voltage is applied. Also, it is necessary to take appropriate measures to protect the capacitor against overvoltage in the case of large pulse surge, and it has a wide temperature range and can be used at a temperature of -40°C to +105°C .

The working principle of ELXY160ETD681MJ20S is traditional. First, the positive side of the direct current power supply is connected to the aluminum foil, and the electrolyte dissolves the metal oxide layer on the surface of the aluminum foil to form a uniform thin electrolyte layer. This layer acts as an insulating layer, and its capacitance is determined by the area of the aluminum foil and its relative distance to the cathode wire. Secondly, if the device is connected to an AC power source, the electrolyte molecules form an equivalent bridge between the anode and the cathode, which allows a certain amount of current to flow through the capacitor until it reaches the peak value. After peak, it will open the bridge momentarily until the reverse current starts to flow in the other direction.

In terms of application field, ELXY160ETD681MJ20S is most suitable for machines, instruments, audio-visual equipment, telecommunications, automobile and other radio electronic products.

In conclusion, except for its application field and working principle, ELXY160ETD681MJ20S also has many other characteristics, such as the size of the product, its capacitance range and the rated voltage. Considering all of these factors, this aluminum electrolytic capacitor can be used for various purposes, which makes it one of the most popular products in the market today.
