Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors, or aluminum electrolytic capacitors, are electronic components used as part of the electronic data processing medium in computers, communications systems, instrumentation equipment, aircraft navigation systems, and electronic control systems.The simplest type of aluminum electrolytic capacitor is an aluminum foil coated with electrolyte, an anode, and a cathode sandwiched between two insulating sheets.

ALF20C271DF550 application field and working principle

The ALF20C271DF550 is a miniaturized aluminum electrolytic capacitor manufactured by EPCOS. It is characterized by low impedance, low TRR and a robust design with a long service life. The capacitor is used in applications requiring a low impedance and enhanced pulse stability. This includes automotive, industrial, aerospace, and other applications where high current capability and low ESR are important factors.

The working principle of the ALF20C271DF550 is based on its physical construction. It consists of an aluminum foil responsible for driving the current, an electrolyte responsible for providing the charge stored in the capacitance, a cathode and an anode. The current flows out of the anode to the cathode when activated. The capacitance of the capacitor is determined by the total surface area of the anode and cathode which is created by the presence of the electrolyte between them forming an electric field. The capacitance is increased as the electrolyte layer thickens.

The ALF20C271DF550 capacitor is also characterized by robust construction with an extremely long service life. It is rated for operational temperatures up to 125°C and heavy shock and vibration conditions with its hermetically sealed case and RFI ripple suppression, making it suitable for automotive applications. The ALF20C271DF550 capacitor is also available in a range of capacitance values, making it suitable for a broad range of applications.

The ALF20C271DF550 capacitor is an ideal choice for applications requiring low impedance, low TRR and maximum pulse stability. Its low ESR enables high current capability, while its robust construction and operational temperature range makes it suitable for a wide range of applications. The ALF20C271DF550 capacitor is the perfect choice for automotive, industrial, aerospace and other applications.
