LKL Series Aluminum Electrolytic Capacitors: Empowering the Stable Heart of Future Electronic Systems

In today's rapidly evolving electronic technology landscape, the reliability and performance of components directly determine the stability of the entire system. YMIN's LKL series aluminum electrolytic capacitors, the "stable heart" of electronic circuits, demonstrate irreplaceable value in numerous applications with their exceptional high-temperature tolerance, long service life, and stable electrical properties.

An Engineering Masterpiece that Breaks Temperature Limits

The LKL series' most striking feature is its exceptional high-temperature performance. Even in extreme operating environments of up to 130°C, the series maintains stable operation for 2,000-5,000 hours, a benchmark in the industry. This extraordinary temperature resistance is the result of YMIN's continuous innovation in electrolyte formulation and packaging processes, enabling LKL capacitors to maintain capacitance stability in high-temperature environments and effectively resist the effects of thermal aging.

Compared to traditional electrolytic capacitors, the LKL series maintains a capacitance change rate within a range of ±20%-±30% at high temperatures—a stability crucial for precision electronic devices. Especially in power supply applications, components often need to withstand high temperatures for extended periods. This characteristic of the LKL series ensures reliable system operation under extreme conditions.

A Perfect Combination of Precision Construction and Superior Performance

The LKL series features a radial lead design with diameters ranging from 5mm to 18mm, meeting various space requirements. The product voltage range covers 10V to 450V DC, and capacitance values ​​range from 0.47μF to 4700μF, providing design engineers with a wide range of options.

The LKL series offers excellent electrical performance. Its leakage current is strictly controlled within a range of 0.01CV to 0.02CV + 10μA, ensuring efficient energy storage. The loss tangent (tanδ) remains at an excellent level of 0.08-0.2, depending on the voltage level. This means that the capacitor generates less heat during energy conversion and achieves higher efficiency.

The LKL series also boasts extremely low equivalent series resistance (ESR), maintaining stable performance even in high-frequency environments. This characteristic makes it particularly suitable for handling high-frequency ripple currents, providing an ideal solution for high-frequency applications such as switching power supplies.

Engineering Guarantees Long Life and Reliability

The LKL series has passed rigorous durability testing, demonstrating that all parameters meet regulatory requirements even when subjected to rated voltage and ripple current at 130°C. Depending on the product size, its load life ranges from 2,000 to 5,000 hours, a feat demonstrated by YMIN's deep understanding of materials science and manufacturing processes.

Durability testing of the product shows that after standard testing, the capacitance change rate, loss tangent, and leakage current remain within specified ranges. This stability ensures the device's reliability over long-term use. Furthermore, the LKL series maintains excellent performance after 1,000 hours of storage at 105°C without load, ensuring long-term inventory and backup availability.

Wide Application Scenarios and Industry Value

The automotive electronics field is a key application area for modern aluminum electrolytic capacitors. The LKL series is AEC-Q200 certified and fully complies with automotive electronics industry standards.
