Aluminum electrolytic capacitors consist of an anode made from an aluminum foil covered with an oxide layer, a paper spacer soaked in electrolyte, and a cathode made of an aluminum foil, all wound in a cylindrical container filled with an electrolyte. The most common aluminium electrolytic capacitors are rated for 25V and up.One such device, 511D107M160ER4D, is used as an electrolytic filtering capacitor in various radio applications. As the electric potential changes across the oxide layer, the capacitance of the device varies, resulting in filtering of the AC signal passing through it.

511D107M160ER4D is mainly used in radios or low voltage AC power filter applications, such as automotive audio equipment, TV and audio amplifiers and loudspeakers, and DC-DC converters. Most common applications of this device are power supply for transmitters, voltage stabilization circuits, and timing circuits. Its rated temperature ranges from -55°C to +105°C.

The structure of the 511D107M160ER4D device consists of a dielectric liquid electrolyte, an anode made of aluminium and containing an oxide layer, and a cathode, also made of aluminium, that is wound around the anode creating a cylindrical body. The anode and the cathode are separated by a paper spacer. To achieve an effective electrical contact between the anode and the cathode, a conductive path is established via a thin layer of electrolyte conforming to the anode surface.

The working principle of 511D107M160ER4D is a type of capacitive behaviour, well known as the electrolytic capacitor. Its main property is based on the use of an oxide layer along the anode, acting as a dielectric material. During operation, the oxide layer allows only the positive ions from the electrolyte to pass through it. These ions will be attracted to the cathode causing a charge accumulation on both plates. As the voltage is applied across the capacitor, the amount of ions passing through the oxide layer increases, resulting in a higher capacitance for the positive cycle.

The most common operating range of 511D107M160ER4D ranges from -60 °C up to 160 °C. It can support a rated voltage of 25V DC and a peak voltage of 50V DC. This type of capacitor also presents an excellent frequency response from 25Hz up to 100kHz. Its operation life is rated at 2000 hours at 40°C.

In conclusion, 511D107M160ER4D aluminum electrolytic capacitors can be used in many radio applications, such as voltage stabilization circuits, and timing circuits. Its structure contains a dielectric liquid electrolyte, an anode and a cathode, all wound in a cylindrical container.
