Leading the Energy Future: YMIN SDS Series Supercapacitors – A Superior Choice for High Energy, Long Lifespan, and Miniaturization

In today's era of pursuing efficient and sustainable energy solutions, a revolutionary device combining the rapid charge-discharge capabilities of traditional capacitors with the high energy storage characteristics of batteries is increasingly gaining attention – the supercapacitor. As a leading electronic component manufacturer in China, YMIN, with its advanced SDS series radial leaded supercapacitors (EDLCs), offers cutting-edge solutions to energy challenges across various industries thanks to their superior performance, reliable stability, and broad application prospects.

I. Core Product: Technological Excellence, Defining New Standards

YMIN's SDS series supercapacitors are not ordinary energy storage components; they are the product of a sophisticated combination of electrochemical technology and materials science. Their working principle is based on the highly efficient electron double-layer (EDLC) effect, storing energy through the rapid adsorption and release of ions at the electrode-electrolyte interface. This mechanism allows them to overcome the limitations of slow chemical reactions in traditional batteries, achieving a significant leap in performance.

This product series upholds Sunmax Electronics' consistent precision manufacturing process and possesses the following core characteristics:

• Superior Energy Density and Miniaturized Design: The SDS series achieves significant energy storage within a compact size. With diameters ranging from a mere 5mm to 18mm and lengths from 9mm to 40mm, it offers a wide range of capacitance values ​​from 0.5 Farads to as high as 70 Farads. This combination of high energy density and miniaturization makes it an ideal energy storage solution in space-constrained modern electronic devices, easily achieving "small size, big energy."

• Stable High Operating Voltage of 2.7V: The entire series has a rated operating voltage of 2.7V, which provides a higher operating energy window (E=1/2CV²) for a single capacitor, meaning that more energy can be stored and released with the same capacitance, improving overall energy efficiency.

• Ultra-Long Cycle Life and Excellent Durability: This is one of the most significant advantages of supercapacitors compared to batteries. The ymin SDS series undergoes rigorous testing. Even at +70°C, after 1000 hours of continuous application of the rated voltage, its capacitance change rate remains within ±30% of the initial value, and its internal resistance (ESR) increase is less than four times the initial standard. This means it can withstand tens or even hundreds of thousands of deep charge-discharge cycles with minimal performance degradation, significantly reducing equipment maintenance costs and replacement frequency.

• Wide operating temperature range and excellent environmental adaptability: The product can operate stably within a harsh temperature range of -40°C to +70°C. Even at -25°C, its ESR only increases to less than four times the specified value, ensuring reliable start-up and operation in cold regions or extreme industrial environments. Simultaneously, its moisture resistance (500 hours of continuous operation at +25°C and 90% relative humidity) is also excellent, meeting the application requirements of complex operating conditions.

• Fast charge-discharge capability and high power density: The SDS series features extremely low internal resistance (ESR), supporting rapid discharge at milliampere and even ampere levels. It can charge in seconds and instantly release enormous power, making it perfect for scenarios requiring instantaneous bursts of power or rapid energy replenishment.

• Environmental Compliance: The product fully complies with international environmental directives such as RoHS and REACH, demonstrating Sunmax Electronics' commitment to environmental protection and sustainable development.

II. Practical Applications: Empowering Industries and Solving Core Pain Points

The value of Sunmax Electronics' SDS series supercapacitors is fully demonstrated in their wide range of practical applications. It is not merely a simple energy storage element, but a key component for improving system performance, achieving energy-saving innovation, and ensuring reliable operation.

1. Smart Meters and Internet of Things (IoT) Devices: Guardians Who Never Lose Data

In smart meters, water meters, gas meters, and various remote monitoring terminals, SDS supercapacitors play a crucial role as backup power sources. When the main power source (such as a battery) is interrupted due to replacement or failure, the supercapacitor can instantly take over power, ensuring the device completes its final data recording and safely shuts down, preventing the loss of critical data. Its long lifespan perfectly matches the 10-year or even longer lifespan requirements of smart meters, avoiding the hassle of frequent battery replacements and achieving a "maintenance-free" design. For example, models SDS2R7L1050512 (1F) or SDS2R7L1550611 (1.5F) are favored in such applications due to their compact size and sufficient power.

2. Consumer Electronics and Smart Home: The Hidden Hero for Enhanced User Experience

In consumer electronics products such as video doorbells, smart locks, and remote controls, SDS supercapacitors are used for flash driving, real-time clock (RTC) backup, and peak power assistance. When a smart lock performs fingerprint recognition or motor startup, it requires a large instantaneous current, which the built-in battery cannot respond to quickly. SDS supercapacitors can easily provide this "burst of power," ensuring the lock opens quickly and smoothly. In video doorbells, it can compensate for peak power when waking up and starting video recording, ensuring smooth, stutter-free video. Models such as SDS2R7L2050809 (2F) are ideal choices for such applications.

3. Industrial Automation and Energy Recovery: The Energy-Saving Engine for Green Factories

In industrial automation, the SDS series is commonly used for energy recovery and peak power buffering in servo drives. When large machinery or robots stop abruptly or descend, a significant amount of regenerative energy is generated. Directly dissipating this energy in resistors would be wasteful. Using SDS supercapacitors can efficiently capture this instantaneous energy and release it during the next acceleration of the equipment, significantly reducing the peak power demand on the power grid, achieving energy savings, and protecting the grid from impacts. Larger capacity models such as the SDS2R7L5061830 (50F) play a central role in such systems.

4. Automotive Electronics and Transportation Logistics: A Reliable Partner for Safety and Efficiency

In automotive intelligent start-stop systems, truck/van power window lifts, and AGVs (Automated Guided Vehicles), SDS supercapacitors provide instantaneous power support during engine start-up or motor operation, reducing battery load and extending battery life. At AGV charging stations, it enables rapid "flash charging," allowing AGVs to replenish sufficient energy and continue operating within tens of seconds, significantly improving logistics efficiency. Its strong environmental adaptability ensures stable operation under harsh conditions such as vehicle vibration and extreme temperature variations.

5. Communication and Security Systems: Emergency Power in Critical Moments

In devices such as routers, base stations, and surveillance cameras, SDS supercapacitors serve as power outage protection. When the mains power suddenly fails, it can immediately provide power to the equipment, supporting the system in completing emergency communications, data storage, or sending alarm information, buying valuable time for repairs and emergency response. Its long lifespan and high reliability far exceed ordinary batteries, making it particularly suitable for outdoor equipment installed in remote locations and difficult to maintain.
