Aluminum-polymer capacitors are devices with a wide range of applications due to their high capacitance values, low leakage currents, and excellent long-term stability. The most common type of aluminum-polymer capacitor, the 156AVG100MFBJ, is a flat, self-healing, electrochemical double layer capacitor that is manufactured with a conductive polymer as the dielectric. It has a wide operating temperature range of -55°C to +125°C and an operating voltage of up to 6.3V.

The 156AVG100MFBJ is a low-profile device, designed to reduce board space requirements due to its flat geometry. This type of aluminum-polymer capacitor also has a low ESR and low leakage current, making it ideal for high-frequency applications and radio-frequency circuits. Additionally, its high capacitance values and long-term stability make it suitable for long-term storage in portable electronic devices.

The working principle of the 156AVG100MFBJ is based on a self-healing electrochemical double layer capacitor that uses a conductive polymer and an aluminum foil as the two electrodes. In this capacitor, the two electrodes are separated by an electrically conductive polymer film, which acts as the dielectric. The aluminum foil and the conductive polymer are connected through a conducting bridge, which is composed of oxidized aluminum particles.

When a voltage is applied to the capacitor, the two electrodes become polarized. This polarization creates an electric double layer, consisting of positive and negative ions, which stores energy as electric charge. This energy is then released when the voltage is removed, allowing for a rapid discharge of the capacitor.

In addition to its high capacitance values and long-term stability, the 156AVG100MFBJ also has self-healing properties. This means that it can withstand large surges of current without failing. This is due to the fact that the conductive polymer becomes ionized when an over-voltage charge is applied, thus re-establishing the conductive bridge between the electrodes.

The 156AVG100MFBJ is an incredibly versatile device and its broad application field and capabilities make it a popular choice for many applications. It is commonly used for energy storage applications, such as for supercapacitors, battery protection, and energy smoothing circuits. It is also used for signal filtering, such as for low-noise, high-frequency signal conditioning circuits, as well as for RF antenna matching.

In conclusion, the 156AVG100MFBJ aluminum-polymer capacitor is a versatile and reliable device with a broad range of applications. Its high capacitance values, low leakage current, and self-healing properties make it well-suited for energy storage applications, signal filtering, and many other types of circuits. Its small size and flat geometry make it ideal for use in space-constrained applications.
