Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, with 16ZLQ3900MEFC12.5X25 as the model number, are temperature-resistant, high-capacity capacitors that are used to store electrical energy, to filter electrical signals and to protect electrical circuits from overvoltage and electrical surges.

Application Field

Aluminum electrolytic capacitors are primarily used in circuit boards where space may be a major limitation. Due to their cylindrical shape, they can be placed close together, enabling them to be used as filtering and voltage regulating components in many different electronic devices. These devices include: computers, TVs, radios, car audio systems, remote control toys, cell phones, power supplies, electronic switches, gaming systems, and a variety of other audio/visual equipment.

Working Principle

An aluminum electrolytic capacitor works by forming two conductive layers of metal foil separated by a dielectric material such as a synthetic rubber-like material. When a voltage is applied across the two layers, the positive charge accumulates on one side and the negative charge accumulates on the other. The electric field created between the layers as a result of this charge separation induces a static charge on the dielectric material, thus forming a capacitor.

As the capacity of this capacitor increases, so does its capacitance and stability. To increase its capacitance, multiple metal layers are formed and connected together with an electrolyte solution. This solution serves to further increase the capacitance and stability of the capacitor by allowing additional electrical charges to be built up in the anode layer.

The 16ZLQ3900MEFC12.5X25 aluminum electrolytic capacitor is rated for up to 12.5mm of diameter and 25mm in height. The temperature range for this capacitor is rated from -55°C to +125°C.

Conclusion

Aluminum electrolytic capacitors are widely used in a variety of applications due to their high stability and relatively low cost. The 16ZLQ3900MEFC12.5X25 is an example of an aluminum electrolytic capacitor with a temperature range of -55°C to +125°C and is used in several types of electronic devices, most notably in circuit boards where space is limited. As for its working principle, it accumulates electrical charges between its two conductive layers of metal and dielectric material to create an electric field, forming a capacitor.
