Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitors that are commonly used to store electric energy. These capacitors are constructed of two conductive aluminum foil plates and an electrolyte, typically an organic solvent. The conductive plates are separated by a thin insulating layer, which is typically a polymer-coated paper.

The EEE-FT1C470AR is one type of aluminum electrolytic capacitor. It is a radial leaded type containing a tantalum core and is encased in a black plastic housing with a minimum diameter of 13 mm. It is designed to have a 22.5mm x 6mm footprint. This makes it ideal for applications where space is limited.

What is an EEE-FT1C470AR?

An EEE-FT1C470AR is a type of aluminum electrolytic capacitor. It is typically used for buffer energy storage, memory reset and backup, power conditioning, and DC-DC converters. It is characterized by a choice of values from 0.47uF to 47,000uF. Its operating temperature ranges from -40C to 85C and its capacitance tolerance (CT) is +20/-85%. It also has a ripple current rated up to 10,000mA at +25C, and its dielectric strength is 250VAC for 8 seconds minimum.

Working Principle

The working principle of the aluminum electrolytic capacitor is based on the concentration of the electrolyte ions. When a voltage is applied across the two plates, an electric field is created and induces an electric charge onto the plates. This charge is then stored in the capacitor as a “capacitance”. The capacitance is a measure of the amount of electric charge stored in the capacitor.

In addition to storing electric charge, the aluminum electrolytic capacitor also offers electrical insulation between the two terminals, allowing it to act as an AC filter capacitor. Its aluminum-oxide dielectric also provides an insulation to prevent electrical shock. This capacitor is also self-healing, meaning it can continue to store electric charge even after the applied voltage is removed.

Application Field

The EEE-FT1C470AR aluminum electrolytic capacitor is used in a variety of fields. It is often used in audio equipment, such as speaker systems, in medical devices and in a variety of power supplies. It is also used in some automotive applications, including engine and brake controllers, air conditioning systems and DC-DC converters. It is also used in motor control panels and some lighting fixtures. Due to its compact size, it is also often used in mobile and embedded gadgets.

In addition to its many application fields, the aluminum electrolytic capacitor has other advantages. It is relatively inexpensive, has a low equivalent series resistance, is relatively stable when exposed to shock and temperature variations and is generally reliable. It is also widely available in a variety of values and sizes.

Conclusion

The EEE-FT1C470AR aluminum electrolytic capacitor is a widely used type of capacitor. It is characterized by a choice of values from 0.47uF to 47,000uF, a choice of values from -40C to 85C, and a ripple current rating of up to 10,000mA at +25C. Its many application fields include audio equipment, medical devices, power supplies, automotive applications, motor control panels, and some lighting fixtures. Although relatively inexpensive and widely available, the aluminum electrolytic capacitor is also highly reliable and offers some electrical insulation.
