In the energy and industrial power sectors, YMIN’s capacitor portfolio addresses diverse applications—ranging from DC-link and filtering for renewable energy generation to reliable power supply startup in extreme cold and the requirements for equipment miniaturization. The company offers a solution matrix characterized by wide operating temperature ranges, high reliability, and long service life. Discover more solutions at Booth D28, Hall 16.
PART 02: Power Capacitor Solutions for Energy and Industry
1) Photovoltaic (PV) Inverters: PV inverters perform the critical task of converting DC to AC for grid connection. Facing the dual challenges of fluctuating sunlight and voltage spikes caused by switching, the capacitors used must simultaneously fulfill three roles: voltage stabilization and filtering, energy storage and discharge, and buffering and protection. Leveraging core strengths such as high capacitance density and high ripple current tolerance, YMIN’s capacitor solutions offer flexible selection options:
2) LKD Series Ultra-High-Capacity High-Voltage Aluminum Electrolytic Capacitors
As power densities in photovoltaic inverters and industrial power supplies continue to rise and unit sizes shrink, traditional snap-in capacitors are increasingly becoming a bottleneck for component layout due to their bulky size. YMIN’s LKD series—a line of ultra-high-capacity, high-voltage liquid radial aluminum electrolytic capacitors—delivers equivalent or superior electrical performance in a smaller package, directly resolving the conflict between the need for high power and compact dimensions.
For the same voltage and capacitance ratings, the LKD series offers a reduction of approximately 20% in both diameter and height compared to snap-in capacitors; if the height remains constant, the diameter can be reduced by nearly 40%. This reduction in size comes without compromising ripple current handling capability—the ripple current rating matches that of equivalent snap-in capacitors and meets Japanese industry standards. Crucially, the LKD series offers more than double the lifespan of snap-in capacitors and a voltage rating approximately 30–40V higher than Japanese brands, making it an ideal solution for miniaturizing input-stage filter capacitors in high-power power supplies and energy storage systems. We invite you to visit our booth to learn more about the LKD series specifications and selection support.
3) LKC Series Ultra-Low-Temperature Capacitors
In applications such as military-grade equipment, railway power systems, and charging piles operating in frigid environments, the electrolytes in traditional high-voltage aluminum electrolytic capacitors suffer from a sharp increase in viscosity and a precipitous drop in conductivity at low temperatures; capacitance typically degrades by over 50–60% at -55°C, and the capacitors become virtually non-functional at -65°C. By utilizing a proprietary low-temperature, high-voltage electrolyte formula and an optimized internal structure, YMIN’s LKC series extends the operating temperature range from the standard -55°C–+105°C to -65°C–+105°C. Actual testing shows a capacitance drop of only about 8.78% at -55°C (compared to the industry norm of over 50%) and an average drop of just 15.96% at -65°C, ensuring reliable startup and stable operation in extreme cold. In certain applications, the LKC series can replace all-film capacitor solutions; leveraging the higher capacitance density of liquid-electrolyte capacitors, a single LKC unit can replace four film capacitors, significantly reducing both component volume and Bill of Materials (BOM) costs. Recommended models include: LKC 450V 150μF (18×40), LKC 450V 220μF (18×50), and LKC 500V 100μF (18×35).

4) Bluetooth Thermometers / Electronic Pens
In applications involving Bluetooth thermometers and electronic pens, the limitations of traditional battery solutions—specifically regarding battery life, instantaneous current output, and physical size—have become bottlenecks. YMIN’s supercapacitors, designed specifically for small smart devices, offer core advantages such as rapid charge/discharge capabilities, long service life, and safety/eco-friendliness, providing an ideal energy storage solution for portable devices like Bluetooth thermometers and electronic pens.
| Capacitor Type | Product Image | Recommended Series | Specification | size | temperature |
| Hybrid Supercapacitor | SLX | 3.8V 10F | 4*25 | -20℃~85℃ | |
| Electric Double-Layer Supercapacitor | SDS | 2.7V 2.0F | 4*25 | -40℃~70℃ |
5) Cameras/IPCs
Security surveillance cameras, IPCs, and similar devices operate continuously (24/7), placing rigorous demands on the stability and longevity of their power supply modules. YMIN offers solutions featuring both solid-state and liquid-electrolyte SMD aluminum electrolytic capacitors; low-ESR designs effectively suppress high-frequency ripple, while high-capacitance, long-life characteristics ensure stable bus voltage, collectively preventing frame loss during image capture and transmission caused by power fluctuations.
Additionally, to meet the backup power requirements of device RTC chips, YMIN’s SDV series SMD supercapacitors serve as an alternative to coin-cell batteries. They offer rapid charging, a cycle life of 100,000 to 500,000 cycles, and a maintenance-free service life, ensuring the clock remains accurate and data is preserved even during power outages.
