Multilayer Polymer Solid Aluminum Electrolytic Capacitors: A Core Component Revolutionizing Electronic Device Performance

As modern electronic devices pursue efficiency, stability, and miniaturization, capacitors, as key passive components in circuits, have a direct impact on overall system reliability. YMIN's multilayer polymer solid aluminum electrolytic capacitors represent a major advancement in capacitor technology, combining the advantages of multilayer polymer and solid electrolyte technologies to provide a novel solution for the electronics industry.

Technical Features and Innovative Design

Multilayer polymer solid aluminum electrolytic capacitors use aluminum foil as electrodes, separated by a solid electrolyte layer, enabling efficient charge storage and transfer. Compared to traditional aluminum electrolytic capacitors, this innovative design offers multiple performance improvements: an operating voltage range of 2.5-50V and a capacitance range of 22-1200μF, while maintaining extremely low equivalent series resistance (ESR) and excellent frequency characteristics.

The product boasts an extremely wide operating temperature range (-55°C to +105°C), ensuring stable operation in extreme environments. Its loss tangent at 120Hz/20°C is lower than that listed for standard products, and its leakage current is extremely low, demonstrating excellent electrical performance. This product complies with the environmental requirements of the RoHS Directive (2011/65/EU) and guarantees a service life of over 2000 hours.

Performance Analysis

High Working Voltage Capability: The operating voltage range of this multilayer polymer solid aluminum electrolytic capacitor is significantly higher than that of conventional products, with a maximum rated voltage of 50V and a surge voltage capability of 1.15 times the rated voltage. This feature makes it particularly suitable for high-voltage applications such as power converters and electric drive systems.

Low ESR: Equivalent series resistance is a key performance metric for capacitors. This product's solid electrolyte layer effectively reduces ESR, achieving excellent performance at 100kHz/20°C. Low ESR not only increases the capacitor's power density and response speed, but also reduces energy loss, improving overall system efficiency.

Long Life and High Reliability: After 2000 hours at 105°C with rated operating voltage, the capacitance change rate does not exceed ±20% of the initial value, and the leakage current remains within the initial specification. The product also demonstrates excellent stability after high-temperature and high-humidity testing.

Excellent Frequency Characteristics: The product's rated ripple current frequency correction factor reaches 1 in the high-frequency range of 100-300kHz, demonstrating excellent performance even in high-frequency environments. This characteristic is particularly important for modern high-frequency switching power supply applications.

Practical Applications
