The service life of ultra-small aluminum electrolytic capacitors

15 Jul,2022

Although small- and medium-power switching power supplies and high-power switching power supplies differ in their switching frequencies, the role of rectifier filter capacitors is essentially the same: they primarily use filter capacitors to absorb current flows at the switching frequency and its higher harmonic frequencies, thereby filtering out ripple voltage.

Features of Solid-State Capacitors and Ultra-Small Electrolytic Capacitors

21 Jul,2022

The dielectric of liquid electrolytic capacitors is a liquid electrolyte. At high temperatures, the liquid particles become highly active, generating pressure inside the capacitor. Since its boiling point is not very high, there is a risk of the capacitor bursting. Solid capacitors, on the other hand, use polymer dielectrics. At high temperatures, the expansion or activity of solid particles is lower than that of liquid electrolytes, and their boiling points can reach as high as 350 degrees Celsius; thus, bursting is virtually impossible. Theoretically, solid-state capacitors are almost entirely immune to bursting.

Ultra-small electrolytic capacitors are widely used in various circuits.

28 Jul,2022

Ultra-small electrolytic capacitors are widely used in a variety of circuits. Since the insulating layer of these capacitors is formed by an extremely thin oxide film on the metal electrodes, they can achieve very high capacitance—ranging from several microfarads to several farads. They are employed in power supply energy-storage and filtering circuits where precision requirements are relatively low but high capacitance is essential.

What are the functions and applications of slender electrolytic capacitors?

01 Aug,2022

Capacitors are common components in circuit design and belong to the category of passive devices. Simply put, active devices are those that require an energy (electrical) source, whereas passive devices do not. Thin, elongated electrolytic capacitors also frequently play an important role in high-speed circuits.

What is the role of slender electrolytic capacitors in a circuit?

09 Aug,2022

In a DC circuit, a long and thin electrolytic capacitor behaves like an open circuit. A long and thin electrolytic capacitor is a charge-storage component and one of the most commonly used electronic components. Today, we’ll introduce to you what roles capacitors play in circuits.

What are the principles and functions of slender electrolytic capacitors?

18 Aug,2022

A capacitor consists of two metal electrodes separated by an insulating material known as a dielectric. There are many different types of capacitors, each with its own unique functions. In air-conditioning systems, electrolytic capacitors are often used as filtering components in control circuits. A slender-type electrolytic capacitor is a type of capacitor whose dielectric layer is coated with an electrolyte and features polarity—this ensures that it cannot be connected incorrectly. So, what exactly is the principle behind and what is the function of a slender-type electrolytic capacitor?

The role of slender electrolytic capacitors in circuits

31 Aug,2022

In a power supply circuit, the rectifier circuit converts alternating current (AC) into pulsating direct current (DC). After the rectifier circuit, a large-capacity, slender electrolytic capacitor is connected. Leveraging its charging and discharging characteristics, this capacitor smooths out the pulsating DC voltage from the rectifier, resulting in a relatively stable DC voltage. In practical applications, to prevent fluctuations in the supply voltages of various circuit components due to changes in the load, dozens to hundreds of fine, slender electrolytic capacitors are typically connected at both the power supply’s output end and the load’s power input end.

The operating principle of slender electrolytic capacitors

14 Sep,2022

In electronic circuits, slender electrolytic capacitors are used to block DC from passing through AC signals. They are also employed to store and release electrical charge, functioning as filters to smooth out the pulsating output signal.
