Who are the leading electrolytic capacitor suppliers?

2024-07-04

Electrolytic capacitors, play an important role in filtering, smoothing, and storing energy. With the electronics demand growing, such as electric vehicles, renewable energy, and smart devices demand, the electrolytic capacitor market is booming.

But who are the leading electrolytic capacitors suppliers？Before answering this question, let’s know some basic information of electrolytic capacitors: what are electrolytic capacitors, how to identify an electrolytic capacitors, and how many types are there for electrolytic capacitors？

Basic information of electrolytic capacitors:

An electrolytic capacitor is a capacitor that uses an oxide film made of aluminum, tantalum or other oxidizable metal as a dielectric. Because of its potential for large capacitance, this type of capacitor is used extensively in power supply circuits and similar applications. There are two major categories, using either a water-based (wet) electrolyte or solid electrolyte. Pls see below photos from HONGDA Capacitors.

Photo 1 is standard electrolytic capacitors, water based electrolyte.

Photo 2 is conductive polymer solid electrolytic capacitors.

1.Electrolytic capacitors are with below characteristics:

High Capacitance: Compared to other types of capacitors, electrolytic capacitors offer very high capacitance values, making them ideal for storing large amounts of energy.

Polarity: Electrolytic capacitors have a defined positive and negative terminal. Connecting them with the wrong polarity can damage the capacitor and potentially cause a short circuit.

Low Leakage Current: They generally have lower leakage currents compared to other types of capacitors, ensuring that the stored energy is retained for a longer period.

Wide Range of Capacitance and Voltage: Electrolytic capacitors are available in a wide range of capacitance values and voltage ratings, allowing them to be used in various applications.

2.How to Identify Electrolytic Capacitors?

Identifying electrolytic capacitors is relatively simple. Look for these key features:

2.1 Polarized: They have a clearly marked positive (+) and negative (-) terminal, typically indicated by a plus sign (+) or a minus sign (-). Take the radial lead type electrolytic capacitors for example:

2.2 Aluminum or Tantalum: Electrolytic capacitors are commonly made using aluminum or tantalum as the anode material. This can be identified by the metal casing or markings on the capacitor.

2.3 Size and Shape: They usually come in cylindrical, rectangular, or disc shapes, with sizes ranging from tiny to quite large.

Below is cylindrical size, HCS is the standard 85℃ SMD Electrolytic capacitors.

2.4 Electrolyte: The container of the electrolytic capacitor will likely be filled with an electrolyte solution.

3.The main types of electrolytic capacitors

Based on their construction, characteristics, there are various types, below we list the main categories:

3.1 Aluminum Electrolytic Capacitors: These are the most common type, offering high capacitance and value for money, through-hole and SMD type available, mostly used in industrial, consumer electronics.

HONGDA Capacitors，offer various series, from standard 85 ℃ 105℃ to low impedance, long life series, give you wide solutions.

3.2 Tantalum Electrolytic Capacitors: These boast higher reliability, lower leakage currents, and better temperature stability compared to aluminum electrolytics. They are often used in demanding applications like aerospace and military electronics.

3.3 Solid Electrolytic Capacitors: These use a solid electrolyte instead of a liquid. They offer improved reliability and a longer lifespan, making them suitable for high-temperature and high-vibration environments.

Our solid electrolytic capacitors, replace Panasonic, Nichicon, Rubycon tier 1 brand, lead time: 5weeks only. SMD and through-hole type available.

3.4 Hybrid Electrolytic Capacitors: These combine the properties of aluminum and tantalum electrolytes, providing a balance of high capacitance and high reliability.
