Aluminum electrolytic capacitors are widely used in many electronic equipment, from AC to radio-frequency equipment, and also in industrial equipment, such as motors, lighting, and computers. They are used as part of the signal conditioning circuitry¹ and provide extremely precise and reliable circuit solutions.The 380LQ181M350H022 is one such component, belonging to the family of aluminum electrolytic capacitors manufactured by leading brand, HAT. This specific component is designed to operate in a wide range of temperature conditions, from -25° C to 85°C. It offers an excellent combination of capacitance, voltage, ESR, and ripple current for its relatively small size.

Aluminum electrolytic capacitors offer certain advantages over ceramic and film capacitors. They have a wide range of temperature range and can be used for applications over wider temperature ranges than ceramic capacitors. They also offer higher capacitance at low voltages than ceramic and film capacitors. The disadvantage of aluminum electrolytic capacitors is that they have a relatively low tolerance, meaning that they are less reliable and can degrade quickly under high temperature and high voltage conditions.

The application field and working principle of the 380LQ181M350H022 aluminum electrolytic capacitor operate similarly to other components in the same family. This component has an anode terminal, which is typically the positive one, and a cathode terminal, typically the negative one. The anode and cathode are separated by a special dielectric material, such as an electrolyte, typically aluminum oxide. This dielectric material acts as the insulator or dielectric, which helps to store and release electrical charge when necessary.

The 380LQ181M350H022 capacitor has an anode to cathode voltage rating of 350V DC. This means that the capacitance should not be exceeded more than the specified voltage. The current throughput rating of this component is 0.22A. The ripple current rating of this capacitor is 17.5Amp rms, or 28Amp peak-to-peak.

The capacitor is typically used in applications where a high capacitance is needed in a relatively small form factor, such as audio power supply circuits, or in other electronic circuits requiring a high current capacity in a small space. It is also widely used in switching power supplies, filter circuits, and high voltage rectification circuits.

In switching power supplies, the 380LQ181M350H022 capacitor can be used as a snubber or voltage decoupling capacitor.² A snubber capacitor is used to reduce voltage transients (spikes) that occur when switching power supplies are turned off or on. The voltage decoupling capacitor is used to ensure that the switching power supply produces a more stable output, as the voltage since ripple is reduced.

The capacitor can also be used in filter circuits, such as resonant-circuits. In these circuits, the capacitor works together with a resistor, inductor, or a combination of these components to form a tuned filter network. The 380LQ181M350H022 capacitor helps to reduce any high frequency noise parasitics, as well as any harmonic distortions that can be produced by the circuit.

Lastly, the capacitor is used in high voltage rectification circuits. The capacitor helps to reduce the amount of power lost during the process of high voltage rectification. High voltage rectification is used in electronic equipment to stabilize the voltage levels before the power reaches the circuit. The 380LQ181M350H022 capacitor can help to reduce the amount of power loss during this process by stabilizing the voltage levels.³

These are some of the application fields and working principles of the 380LQ181M350H022 Aluminum electrolytic capacitor. This component is used in numerous electronic circuits due to its combination of size and capacitance, as well as its ability to work in a wide range of temperature conditions. By better understanding the application field and working principles of this capacitor, electronic engineers can more effectively design and implement power and signal conditioning circuitry for modern electronic equipment.
