YMIN SDH Series Supercapacitors: A Revolutionary Force in High-Performance Energy Storage

In today's era of striving for high efficiency, environmental protection, and sustainable development, innovation in energy storage technology has become a core driver of social progress. Supercapacitors, a unique hybrid between traditional capacitors and chemical batteries, are reshaping numerous sectors, from consumer electronics to industrial power and even defense and military applications with their unparalleled performance advantages. YMIN Electronics, China's leading manufacturer of SDH supercapacitors, provides customers with powerful, reliable, and efficient energy solutions with its superior SDH series radial-lead supercapacitors.

I. Core Technology: Setting the Benchmark for Reliability and High Performance

The YMIN SDH series supercapacitors are no ordinary energy storage components; they represent the culmination of a perfect marriage of engineering and electrochemistry. Their core principle is the electrochemical double layer (EDLC), storing energy through the vast electric double layer formed at the interface between the activated carbon electrode surface and the electrolyte. This enables rapid charge and discharge, avoiding the chemical reaction lag and material loss common in chemical batteries.

The most notable features of this series are their exceptional high-temperature tolerance and extremely long cycle life. SDH capacitors maintain stable operation in extreme ambient temperatures up to +85°C and promise a lifespan of up to 1,000 hours of continuous full-load operation. This means they offer unparalleled reliability even in harsh industrial environments. Their wide operating temperature range (-40°C to +85°C) ensures smooth startup and consistent performance, whether in the harsh winters of northern China or the scorching summers of southern China.

The SDH series also excels in electrical performance:

• 2.7V rated voltage: Provides a high energy storage platform per unit volume.

• Wide capacitance range (1F to 70F): Covers diverse needs, from micro-energy backup to high-current pulse discharge. Capacity tolerances are controlled within -10% to +30%, ensuring product consistency.

• Extremely low equivalent series resistance (ESR): Low ESR reduces internal energy loss, resulting in less heat generation during high-current discharge and extremely high efficiency, which is crucial for high-power applications. The product standard clearly stipulates that even at -25°C, its ESR is less than four times the specified value at room temperature, ensuring stable performance across the entire temperature range.

In addition, the product strictly complies with RoHS and REACH directives and uses only environmentally friendly materials, demonstrating YMIN's social responsibility for environmental protection and human health.

II. Strict Quality: Testing and Verification Beyond Standards

YMIN's commitment to quality is reflected in a series of rigorous testing standards that simulate the harshest operating conditions a product may encounter throughout its lifecycle:

• Durability Test: After continuously applying a rated voltage of 2.7V at +85°C for 1000 hours, the capacity change remains within ±30% of the initial value, and ESR degradation is controlled.

• High-Temperature Storage Characteristics: After 1000 hours of storage at +85°C without load, performance degradation also meets strict standards, demonstrating the company's outstanding material stability.

• Humidity Resistance Test: Continuous operation for 500 hours in a humid environment at +25°C and 90% relative humidity fully validated its moisture and corrosion resistance, with the ESR increasing to within three times its initial standard value, far exceeding the industry average.

These tests not only verify product parameters but also provide the ultimate endorsement of YMIN's manufacturing process and quality management system, providing users with the confidence of "maintenance-free" operation.

III. Diverse Applications: "Energy Guardians" Empowering Thousands of Industries

The characteristics of the SDH series supercapacitors guarantee an extremely wide range of applications, quietly transforming the way we live and work.

1. Industrial and Energy:

◦ Energy Recovery and Storage: In smart grids, they are used to smooth the fluctuating output of renewable energy sources (such as wind and solar power), achieving peak load shifting. In industrial automation, they are used to recover the lowering and braking energy of equipment such as lifting machinery, elevators, and automated gantry cranes, significantly improving energy efficiency and reducing operating costs.

◦ Peak Power Assistance and Compensation: Serves as a "power bank" to power devices requiring instantaneous high current. For example, it provides starting current for large diesel engines, inverters, and smart meters, compensating for insufficient battery power density, protecting the main power system, and extending battery life.

2. Transportation:

◦ New Energy Vehicles: In electric and hybrid vehicles, it is used in regenerative braking systems to efficiently recover kinetic energy generated during braking and quickly release it during acceleration, increasing range. It also provides instantaneous starting power for the vehicle's start-stop system, reducing the impact on lead-acid batteries.

◦ Public Transportation: Used in trolleybuses and trams, it quickly charges vehicles upon arrival, allowing them to continue to the next stop, enabling green and efficient public transportation operations.

3. Consumer Electronics and the Internet of Things (IoT):

◦ Backup Power and Data Protection: Provides power to smart electricity, water, and gas meters to protect data during power outages, ensuring data is not lost. It is also used in routers, smart home hubs, and other devices to achieve safe shutdown and enhance the user experience.

◦ Fast Charge and Discharge Devices: Used in devices requiring rapid energy release and replenishment, such as high-speed flashlights, electronic toys, and smart door locks, they offer a faster and more durable solution than batteries.

4. High-End and Specialty Applications:

◦ Military and Aerospace: Due to their long life, high reliability, and wide temperature range, SDH capacitors are widely used in high-end equipment such as submarines, ships, radar systems, and spacecraft, providing stable pulse power and backup energy for critical systems.

◦ Medical Equipment: They provide safe, reliable, and fast-charging energy for portable medical devices such as defibrillators.

IV. Precision Design: Easy-to-Integrate Hardware Solutions

The YMIN SDH series offers a variety of sizes, ranging from 8mm to 18mm in diameter (such as the SDH2R7L1050812 and SDH2R7L7061850). Utilizing a standard radial lead package, the SDH series features a compact design and small size, making it ideal for automated surface mount technology (SMT) or manual soldering installation on space-constrained PCBs. The product drawings are clearly labeled, and the pin spacing (F value) is optimally designed, making layout design easier for engineers and significantly simplifying the user's integration and application process.
