This type of capacitor utilizes both aluminum and polymer materials to deliver robust performance and a wide range of features. The components are light weight, possess excellent electrical and mechanical properties, and have outstanding de-rating characteristics. Additionally, they offer improved reliability due to a lower operating temperature and tighter tolerances.

The 187XMPL004MG19 model aluminum-polymer capacitor has a rated capacitance of 4μF, a rated voltage of 4V, and a rated temperature range of -55°C to +105°C. It is a miniature type of the aluminum-polymer capacitor and is found most frequently in the mobile device market. This type of capacitor has application fields in areas such as high-end smart phones, tablet PCs, and laptop computers. It is usually used together with ceramic capacitors in equivalent circuit compensating designs.

The capacitance of aluminum-polymer capacitors is high at low temperatures and decreases when the temperature rises. This makes the 187XMPL004MG19 model ideal for electronic applications where capacitance stabilization is required. It also helps in dealing with dynamic ranges and the need for high-frequency applications.

The 187XMPL004MG19 model utilizes a polymer dielectric film bonded to an aluminum foil, allowing for highly flexible constructions. This also reduces the equivalent series resistance (ESR) so that the operating temperature of the capacitor is kept lower in comparison to conventional capacitance materials. The 187XMPL004MG19 also offers excellent capacitance retention at high temperatures, allowing it to be operated in higher temperature environments.

The aluminum-polymer capacitor is widely used in a number of electronic applications where its unique properties make it a perfect fit. The advantages include increased switching speed, high capacitance and power density, long-term stability, and excellent voltage handling characteristics. The type of capacitor is also ideal for circuit designs where EMC issues are present as the capacitance value remains stable even with high-frequency variation.

The working principle of the 187XMPL004MG19 aluminum-polymer capacitor is based on the Faraday’s Law of Electrolytic Capacitance. According to this law, the capacitance of a capacitor is inversely proportional to the thickness of the dielectric material between its electrodes. The aluminum and polymer materials used in the 187XMPL004MG19 device allow for a thin and flexible dielectric material between the electrodes, providing high capacitance values despite its small size.

Overall, the 187XMPL004MG19 aluminum-polymer capacitor offers a great combination of features, making it an ideal choice for a wide range of electronic applications. Its miniature size, high capacitance values, and excellent reliability rating make it the perfect choice for a variety of circuits. Its low equivalent series resistance and temperature stability further adds to its appeal, making it an all-around great component for a variety of electronic circuits.
