Aluminum-Polymer capacitors provide reliable operation, low equivalent series resistance (ESR), a wide temperature range, wide frequency response and wide capacitance range. The MAL218197301E3 aluminum-polymer capacitor offers these features in a very small form factor for space-constrained applications.

The MAL218197301E3 aluminum-polymer capacitor has a capacitance rating of 220uF. It is available in an A-sized package that is 2.50mm in height and 7.50mm in diameter. It is designed to be used in applications that require tight space with high temperature and ntegrity such as consumer electronics and power converters. The operating temperature range of the MAL218197301E3 is -55C to +125C.

The MAL218197301E3 aluminum-polymer capacitor offers excellent thermal stability, low leakage current and high frequency response. Its low equivalent series resistance (ESR) provides enhanced ripple current performance and noise reduction. The MAL218197301E3 also has a high volumetric efficiency which makes it suitable for applications where a large capacitance value is needed in a small size.

The working principle of the MAL218197301E3 utilizes a dielectric layer made of alumina or tantalum oxide interposed between two layers of aluminum foil. This combination creates an electrical field that is stored in the capacitor. This electrical field is proportional to the applied voltage and the surface area of the aluminum foil. The stored energy is dissipated through current losses in the capacitor, which is referred to as equivalent series resistance (ESR).

Applications for the MAL218197301E3 aluminum-polymer capacitor include power supplies, electronic devices and motor drives. It is a cost-effective solution for applications where space is limited but high capacitance values are required. Its high ripple current capabilities, low ESR and wide temperature range make it an ideal choice for compact, high performance applications.
