In today's rapidly evolving electronics industry, component reliability and performance are crucial. YMIN Electronics' series of LED aluminum electrolytic capacitors are designed for high-performance applications in harsh environments, particularly in lighting, industrial power supplies, and automotive electronics.
Excellent Product Features
Our aluminum electrolytic capacitors, manufactured using advanced liquid electrolyte technology and high-quality materials, offer a number of exceptional features. They operate stably over a wide temperature range of -25°C to +130°C, and feature a rated voltage range of 200-500V, meeting the needs of most high-voltage applications. Capacitance tolerance is controlled within ±20%, ensuring precision and consistency in circuit design.
Most notable is their high-temperature performance: they offer continuous operation for 2,000 hours at 130°C and up to 10,000 hours at 105°C. This exceptional high-temperature resistance makes them particularly suitable for high-temperature LED lighting applications, such as high-power streetlights, industrial lighting, and indoor commercial lighting systems.
Strict Technical Specifications
Our products meet AEC-Q200 standards and are RoHS-compliant, demonstrating our commitment to both quality and environmental protection. Leakage current is extremely low, adhering to the standard of ≤0.02CV+10(uA), where C is the nominal capacitance (uF) and V is the rated voltage (V). The loss tangent value remains between 0.1-0.2 depending on the voltage. Even for products with a capacitance exceeding 1000uF, the increase is only 0.02 for each additional 1000uF.
The capacitors also offer excellent impedance ratio characteristics, maintaining an impedance ratio between 5-8 within the temperature range of -40°C to 20°C, ensuring excellent performance even in low-temperature environments. Durability testing shows that after exposure to rated voltage and ripple current at 130°C, the capacitance change remains within ±20% of the initial value, while the loss tangent value and leakage current are both less than 200% of the specified values.
Wide Applications
LED Lighting Drivers
Our capacitors are particularly suitable for LED driver power supplies, effectively filtering high-frequency noise and providing stable DC power. Whether used in indoor lighting or outdoor streetlights, they ensure long-term stable operation and reduce maintenance costs.
Industrial Power Systems
In the industrial power supply sector, our products can be used in devices such as switching power supplies, inverters, and frequency converters. Their low ESR characteristics help reduce power losses and improve overall system efficiency.

Complete Product Specifications
We offer a comprehensive product line, covering a wide range of capacitance options from 2.2μF to 68μF at 400V. For example, the 400V/2.2μF model measures 8×9mm, has a maximum impedance of 23Ω, and a ripple current of 144mA. The 400V/68μF model, on the other hand, measures 14.5×25mm, has an impedance of only 3.45Ω, and a ripple current of up to 1035mA. This diverse product line enables customers to select the most suitable product for their specific application needs.
Quality Assurance
All products undergo rigorous durability and high-temperature storage testing. After 1000 hours of storage at 105°C, the product's capacity change rate, loss tangent, and leakage current all meet specified standards, ensuring long-term product reliability.
We also provide detailed frequency and temperature correction coefficients to facilitate engineers in accurately calculating ripple current values under different operating conditions. The frequency correction coefficient ranges from 0.4 at 50Hz to 1.0 at 100kHz; the temperature correction coefficient ranges from 2.1 at 50°C to 1.0 at 105°C.
