YMIN SDB Series 3.0V Supercapacitors: A Higher Voltage Platform, Empowering a New Era of Efficient Energy

With the rapid advancement of energy storage technology, supercapacitors, serving as a bridge between traditional capacitors and chemical batteries, have become a key component in numerous industries due to their unique advantages. YMIN Electronics, with its deep industry expertise, has launched the SDB Series 3.0V radial-leaded supercapacitors. With their higher rated voltage, excellent power characteristics, and stable service life, they offer the market a high-performance solution, enabling customers to iterate and innovate their products.

I. Core Technology: Integration of High Voltage and High Performance

The YMIN SDB Series supercapacitors utilize an advanced electrochemical layer capacitor (EDLC) principle and a winding process. While maintaining the inherent advantages of supercapacitors, they increase the rated voltage to 3.0V. This increase allows a single component to store more energy (higher energy density) within the same volume, reducing the number of series-connected cells required in applications, simplifying circuit design, and improving overall system reliability.

This series operates within a temperature range of -40°C to +70°C, ensuring stable operation in a variety of challenging environments. It is guaranteed to operate continuously at full load for 1000 hours at +70°C, demonstrating its excellent high-temperature tolerance and long service life. Key electrical features include:

• 3.0V rated voltage: Provides a higher energy storage platform for optimized energy efficiency.

• Wide capacity range (1F to 160F): Meets diverse needs, from low-current backup to high-power pulse discharge, while ensuring batch consistency.

• Low equivalent series resistance (ESR): Extremely low ESR ensures minimal internal losses, high efficiency, and low heat generation at high power output. Standards stipulate that even at -25°C, the ESR is less than four times the room temperature value, ensuring stable performance across the entire temperature range.

This product fully complies with RoHS and REACH directives, utilizes environmentally friendly materials, and adheres to green manufacturing principles.

2. Rigorous Testing: Guaranteeing Quality and Reliability

YMIN conducts a series of rigorous tests and verifications on the SDB series products, simulating extreme operating conditions to ensure their long-term reliability:

• Endurance Test: After continuously applying a rated voltage of 3.0V at +70°C for 1000 hours, the capacity change rate remains within ±30% of the initial value, and ESR change is controllable.

• High-Temperature Storage Characteristics: After 1000 hours of no-load storage at +70°C, product performance degradation meets standards, demonstrating excellent material stability.

• Humidity Resistance Test: After 500 hours of continuous operation at +25°C and 90% relative humidity, the product demonstrates excellent moisture and corrosion resistance, with the ESR increasing to within three times the initial standard value.

These tests not only verify the stability of product parameters but also demonstrate YMIN's rigorous quality control system, ensuring reliable and durable products for users.

III. Diverse Applications: The "Energy Engine" for Thousands of Industries

The characteristics of the SDB series 3.0V supercapacitors make them suitable for a variety of scenarios requiring high voltage, high power, and fast charge and discharge speeds:

1. Smart Metering and IoT:

◦ Smart electricity, water, and gas meters: As power supplies for power outage protection, the 3.0V voltage can be directly or simply stepped down to match the operating voltage of the host MCU, providing continuous power during grid anomalies, enabling data storage and communication alerts to ensure data security.

◦ IoT terminal devices: Provide energy harvesting, storage, and peak power support for distributed sensor nodes, adapting to complex environments.

2. Consumer Electronics and Portable Devices:

◦ Smart home products: Such as smart door locks, security cameras, and video doorbells, provide peak current for motor driving, extending battery life or serving as a backup power source.

◦ Portable devices: Provide fast charge and discharge cycles in electric toys, flashlights, and handheld medical devices, improving the user experience.

3. Industrial Control and Energy Management:

◦ Industrial PLCs and Servo Drives: Used for data backup and emergency status maintenance during power outages, supporting safe system shutdown or rapid recovery.

◦ Energy Harvesting Systems: Harvest weak energy sources such as solar energy and vibration energy and provide instantaneous high-power output for wireless transmission.

4. Transportation and Communications:

◦ Automotive Electronics: Provide backup power for in-vehicle entertainment systems and advanced driver assistance systems (ADAS), or assist in start-stop systems.

◦ Communications Equipment: Ensure continuous operation in base stations and routers after short power outages, maintaining smooth communication links.

IV. Precision Design: Easy Integration and Diverse Options

The YMIN SDB series offers a variety of sizes ranging from 8mm to 22mm in diameter (such as the SDB3R0L1050812 and SDB3R0L1672255). Utilizing a standard radial lead package, the compact design and small size make it suitable for automated PCB placement or manual soldering. The standardized product sizes and optimally designed pin pitch (F-value) facilitate flexible product selection and layout design, accelerating time-to-market.
