Aluminum electrolytic capacitors, also known as "aluminum electrolytic capacitors" and "electrolytic capacitors", are a kind of capacitors with the widest application range and the most complex structures in all kinds of capacitors. The 337BPA025M is one of the aluminum electrolytic capacitors. It consists of an aluminum foil and a plastic film between the can and the electrodes. Its main application field is power supply circuit, computes, communication and industrial control devices. This article will discuss its representative characteristics, application field and working principle.

Representative Characteristics

The 337BPA025M capacitor has a small size and a two pin design. The size is only 0.14 x 0.07 inches. It also has a flat metal pin, which could ensure the maximum surface contact area. It has a maximum capacitance of 25μF, a maximum working voltage of 35V and a temperature range of -40℃ to 85℃. All these features make it one of the most suitable capacitors used in a small power supply system with low working voltage.

Application Field

Since 337BPA025M has a small size and low working voltage, it is mainly used in power supply circuits, communication systems and computer industry. In terms of power supply circuits, the capacitor is used as a filter or a bypass capacitor, blocking the high-frequency noise, wide band noise and interference signals. It can significantly reduce the impact and noise from other circuits. For the communication systems, the capacitor can be used as a leak storage device and pre-amplifier stabilization. The capacitor can also be used as a signal buffer and stabilize the pre-amplifier. In the computer industrial, due to its small size, the capacitor can be embedded in the motherboards for providing additional protection.

Working Principle

The 337BPA025M capacitor has a two-terminal design. It has a positive electrode which is made of a high corrosion resistant oxide film and a negative electrode which is an aluminum foil. This ensures that the two electrodes have good contact and use the electric field generated between oxides and aqueous solutions to store electricity. The aluminum foil is a conductive medium and is filled with an electrolyte that enables current flow. When the capacitor is in use, it will absorb some of the charges near the positive terminal. Then electrostatic field will be created between the positive and negative electrodes, causing current to flow from the positive to the negative electrodes.

In summary, the 337BPA025M is one of the most popular aluminum electrolytic capacitors. It has a small size and low working voltage, which makes it suitable for power supply filter, communication systems and computer industrial. In addition, its working principle is based on the electrostatic field created between the positive and negative terminals. All these advantages ensure the 337BPA025M is a good choice for different areas.
