What is an Aluminum Electrolytic Capacitor?

An aluminum electrolytic capacitor is a capacitor that utilizes two aluminum electrodes, separated by a paper or polymer dielectric, for their electrical energy storage capacity. Aluminum electrolytic capacitors are highly reliable due to their ability to provide a consistent electrical storage in spite of high temperatures or vibrations. Due to their small size, good performance and reliability, they are an ideal choice for a variety of consumer and industrial applications.

Application Field and Working Principle of ECA-2EHG100B

The ECA-2EHG100B is an aluminum electrolytic capacitor designed by Panasonic. It is a radial lead type capacitor based on aluminum electrolytic technology. The capacitor is designed for use in audio-visual equipment, in particular, large flat-screen televisions. Its main purpose is to provide a steady electrical energy supply to reduce the power consumption of the TVs. The ECA-2EHG100B capacitor also has a wide operating temperature range, which makes it suitable for many types of audio-visual equipment where other capacitors may not be suitable.

The operating principle of the ECA-2EHG100B is based on the principle of an electric double-layer capacitor (EDLC). The EDLC works by forming two electric charge layers at the electrodes that store electric energy. The ECA-2EHG100B uses an aluminum foil as the cathode and an organic electrolyte as the anode, which allows the capacitor to provide a steady amount of electric energy even at high temperatures.

The ECA-2EHG100B has a rated capacitance of 100µF and voltage rating of 14V. It has a wide operating temperature range of -55°C to 85°C, making it suitable for use in a variety of environments. Its radial lead construction also makes it easy to mount in circuits that have space constraints. Furthermore, its low inherent ESR (Equivalent Series Resistance) value makes it suitable for applications where low output voltage ripple and noise cannot be tolerated.

Conclusion

The ECA-2EHG100B aluminum electrolytic capacitor from Panasonic is a reliable capacitor for use in audio-visual equipment, particularly large flat-screen televisions. It provides a consistent electrical energy storage capacity over extensive temperature ranges with low ESR values. This makes it an ideal choice for applications where low output voltage ripple and noise are crucial. Understanding its application field and operating principle is essential for those looking to build their own circuits with this capacitor.
