Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the most widely used electrical components today, due to their low cost, high efficiency and long life. They are constructed of two electrodes, one of which is an aluminum foil. This aluminum foil is dipped in an electrolyte solution, which acts as an electrical conductor and allows charges to flow between the two electrodes. The effectiveness and reliability of aluminum electrolytic capacitors depend on their design, as well as the selection and application of the electrolyte.

EEE-FT1A221AP Application Field and Working Principle

The EEE-FT1A221AP is an aluminum electrolytic capacitor with screw terminals and axial leads. It is mainly used in AC circuits to ensure a stable power supply and reduce interference. The main features of the capacitor are excellent high temperature stability, low internal impedance, and long life.

The working principle of the EEE-FT1A221AP is based on Faraday’s law. When an AC voltage is applied to the capacitor, a current flows through the electrolyte. This current creates an electric field between the electrode and the electrolyte which results in the capacitance and the ESR, that is, the capacitance is increased and the ESR is decreased. The EEE-FT1A221AP also has a self-healing property, where the electrodes are slowly smoothed and cleaned from the corrosion by the electrolyte.

The EEE-FT1A221AP has excellent high temperature stability, low impedance, high thermal shock and mechanical strength. It has a maximum operating temperature range of -55°C to +105°C, a typical ESR of 4mΩ, and a capacitance tolerance of ±10%. The life expectancy of the capacitor is typically 12,000 hours.

In addition, the EEE-FT1A221AP is RoHS compliant and is UL certified, which makes it a reliable choice for applications where reliability is of utmost importance. It is also a highly reliable device for various applications such as power supplies, servo motors, electro-pneumatic systems, medical devices and audio applications.

The EEE-FT1A221AP is an ideal choice for applications that require high performance, low ESR and long lasting reliability. It is a reliable and cost-effective solution for applications that require stable power supply and reduce interference. Its excellent high temperature stability and low impedance make it a versatile and reliable device for various applications.
