Aluminum Electrolytic Capacitors

Electrolytic capacitors are energy storage components used to address the ac characteristics of circuits, such as resonance, damping, and filtering. Among various kinds of capacitors, aluminum electrolytic capacitors are the most frequently-used capacitors with the largest capacity in a given volume.

The SEK101M160ST aluminum electrolytic capacitor belongs to a kind of miniaturized capacitors, a PCB simple mounting type aluminum electrolytic capacitor, with a ripple current of 1.6A. Mainly, it is used in a high ripple current environment. It is a popular choice when the application needs a higher capacitance in a small package.

The Working Principle of SEK101M160ST Aluminum Electrolytic Capacitor

Aluminum electrolytic capacitors are provided in a wide range of packaging sizes and capacitance values. They can offer high capacitance with a low ESR (equivalent series resistance). It utilizes a porous anode made from Aluminum foils containing tiny metal particles to provide a large amount of electrical storage in a very small component. The electrolyte in the capacitors is an acidic solution. The SEK101M160ST aluminum electrolytic capacitor is often used in high ripple current applications, in envelopes designed for PCB mounting which includes stamped aluminum plates and plastic sleeve for securing the capacitors to the PCB.

The working principle is to store electric charge in the metal particles and build up a voltage between the electrodes. When an AC voltage is allowed to flow through the capacitor, the electric current flows through the metal particles and causes the metal to become polarized. The electric charge carries a positive and negative charge that results in a higher capacitance value. The capacitance of the capacitor depends on the size of the capacitor, the type of electrolyte used, and the metal particles used in the porous Anode.

Regardless of the voltage applied, when capacitance decreases, it can be attributed to the dry-out of the electrolyte which is a common cause of failure.

The Application Field of SEK101M160ST Aluminum Electrolytic Capacitor

SEK101M160ST aluminum electrolytic capacitors are widely used in modern electronic circuits for signal conditioning, noise filtering, or power supply decoupling. Its application fields are various, including audio jacks, audio amplifiers, high-end audio amplifiers, converters, motor control circuits, audio/video amplifier circuits, motors, and more. The SEK101M160ST aluminum electrolytic capacitor is preferred due to its high capacitance, low inductance, and low ESR (equivalent series resistance). It has the ability to store large amounts of energy in a small package, and therefore is perfect for audio applications that require high-current loads.

Another benefit of using aluminum electrolytic capacitors is that they require less space on your PCB compared to traditional capacitors. This allows you to save considerable cost in your circuit boards. SEK101M160ST aluminum electrolytic capacitors are able to withstand higher ripple and peak currents than traditional capacitors. This is important when you are designing a circuit with high current loads, or one that is subject to significant transient voltages.

These capacitors have a wide range of applications in computers, communication systems, automated analytic instrumentation, and data processing systems. Their ability to store large amounts of energy in a small package makes them perfect for applications that require high-current load. They are also used in energy-saving appliances, and to reduce signal distortion in audio/video amplifier circuits. This is particularly useful in automotive applications due to the high vibration and shock experienced in the vehicle environment.

SEK101M160ST aluminum electrolytic capacitors are also suitable for computer memory boards, PLCs, UPS, industrial control systems, power tools, motor control circuits, and a variety of other industrial applications.
