In core scenarios such as warehousing and logistics, and port terminals, electric forklifts, as high-frequency operating equipment, directly impact operational efficiency due to their continuous operational reliability. However, frequent starts and stops, steering, and sudden load changes leading to jamming, restarts, and even burnout of motor drive components have long plagued industry users. Yongming Electronics has announced that its LKE series aluminum electrolytic capacitors, through breakthroughs in core technologies, have successfully addressed this industry pain point, providing a high-reliability capacitor solution for electric forklifts.

High-Frequency Operations Encounter Bottlenecks: Traditional Capacitors Struggle to Bear the Load

The high-intensity operation of electric forklifts places stringent demands on the energy buffering capacity of the power supply system. Many companies previously used ordinary aluminum electrolytic capacitors, which frequently failed in practical applications. "Our forklifts often suddenly jam when fully loaded, sometimes even restarting, and in severe cases, the MOSFETs burn out. Not only are repair costs high, but it also seriously affects loading and unloading efficiency," a logistics company equipment manager complained to a reporter.

Technical personnel analyzed the problem and pointed out that the root cause lies in the high-frequency ripple current and transient current surges generated during motor speed changes and steering. Ordinary aluminum electrolytic capacitors have a high equivalent series resistance (ESR), which generates a large amount of heat when large currents pass through, causing the capacitor core to overheat, the electrolyte to dry out, and the capacitance to rapidly decay. Failed capacitors cannot buffer energy during sudden load changes, leading to supply voltage fluctuations and ultimately equipment failure.

LKE Series Precisely Addresses the Problem: Four Advantages Strengthen Reliability

Addressing industry pain points, Yongming Electronics has specially developed and launched the LKE series of 105°C 10,000-hour long-life liquid aluminum electrolytic capacitors, achieving a precise solution through four core technological advantages.

In terms of low-loss design, this series uses new electrolyte materials and optimized manufacturing processes, significantly reducing impedance and equivalent series resistance under high-frequency environments, reducing heat loss at the source, and effectively controlling capacitor temperature rise. High ripple resistance is another outstanding highlight. Actual testing shows that this series can withstand ripple current 30%-50% more than ordinary products, easily handling the high-frequency ripple surges generated by motor drives. The rapid charge/discharge transient response of the LKE series allows it to promptly provide or absorb sudden large currents during load changes, effectively buffering voltage fluctuations. Its long-life design of 10,000 hours at 105°C perfectly matches the overall design life of the electric forklift, significantly reducing on-site failure rates and maintenance costs.

Real-world test data confirms stable performance under harsh conditions.

The excellent performance in practical applications fully validates the reliability of the LKE series. An electric forklift manufacturer reported that after replacing the capacitors with this series, the equipment operated smoothly and continuously under high-intensity, harsh conditions, and previously frequent restarts and drive damage issues were completely resolved.

Real-world test data provided by Yongming Electronics shows that compared to traditional solutions, the LKE series capacitors reduce casing temperature rise by more than 20°C, significantly improving lifespan reliability; the motor power supply bus ripple voltage is reduced by approximately 40%, providing a solid guarantee for stable system operation; after 10,000 hours of full-load cyclic stress testing, this series of capacitors showed no failures, fully demonstrating its long-lasting and durable product characteristics.

Adapting to Diverse Scenarios, Facilitating Equipment Upgrades

Currently, Yongming's LKE series capacitors are widely compatible with motor controllers in electric forklifts, electric engineering vehicles, and other equipment, playing a crucial role in power filtering and energy buffering circuits. To meet different operating conditions, the series offers popular models such as 63V 470μF and 100V 470μF, all specifically designed for high-frequency, high-ripple applications.

"For capacitor applications, if you have any problems, turn to Yongming." Behind this market positioning lies Yongming Electronics' unwavering pursuit of technological innovation. The launch of the LKE series not only solves the reliability challenges in the electric forklift industry but also demonstrates the strength of Chinese capacitor companies in replacing international brands in the high-end market. In the future, Yongming Electronics will continue to deepen its presence in the new energy equipment field, empowering global customers with superior products.
