CW3

CW3 Series: Ultra-Low-Temperature, Long-Life, High-Performance Aluminum Electrolytic Capacitors Designed for Harsh Environments

In modern power electronics applications, which demand high efficiency, stability, and reliability, capacitors serve as critical energy storage and filtering components. Their performance directly impacts the lifespan and performance of the entire system. YMIN's CW3 series snap-in aluminum electrolytic capacitors are high-performance solutions designed to meet the demanding requirements of industrial, new energy, and automotive electronics applications.

Core Advantage: Unafraid of Extreme Temperatures, Ensuring Long-Term Operation

The key highlights of the CW3 series capacitors are their exceptional wide temperature adaptability and exceptionally long service life:
• Ultra-Wide Operating Temperature Range (-40°C to +105°C): The CW3 maintains excellent electrical performance even in extreme temperatures as low as -40°C or as high as 105°C. Its capacitance maintains over 65% of its normal temperature value at -40°C and reaches over 80% at -25°C. Impedance variation is also strictly controlled (impedance at -40°C is ≤ 8 times that of normal temperature), ensuring stable system startup and operation in harsh climates or high-heat conditions.

• 3000-hour lifespan at 105°C: Under rated voltage and ripple current load, the CW3 series maintains strict compliance with initial specifications for key parameters such as capacitance variation, loss factor (DF), and leakage current (LC) after 3000 hours of continuous operation at 105°C, ensuring long-term device reliability.

• High-reliability design: Rigorous insulation resistance (≥100MΩ) and withstand voltage (AC 2000V) testing ensure product safety and stability in high-voltage environments.

Excellent Performance: Optimizing System Efficiency and Response

The CW3 series also offers excellent electrical performance:
• Low Equivalent Series Resistance (ESR) and Dissipation Factor (DF): Effectively reduces capacitor self-heating, improving energy conversion efficiency and minimizing system temperature rise, particularly beneficial for thermal management in high-power density designs.

• Low Leakage Current: Meets high industry standards (≤0.94mA or 3CV), helping to reduce quiescent power consumption and extend device standby time.

• Excellent Ripple Current Carrying Capacity: The CW3 series can withstand high ripple currents, and its carrying capacity significantly increases with frequency (up to 1.4 at >10kHz), making it particularly suitable for handling high-frequency current fluctuations in equipment such as switching power supplies and inverters. The product specification sheet provides detailed model ratings for different sizes, facilitating accurate selection.

• Low Inductance (Low LC): Helps suppress high-frequency noise and improve system electromagnetic compatibility (EMC).

Wide Applications: Enabling Innovation in Key Industries

With their ultra-low temperature resistance, long life, high reliability, and excellent electrical properties, the CW3 series capacitors are ideal for the following key applications:

1. Household inverter appliances (such as air conditioner and refrigerator compressor drives): They adapt to frequent starts and stops and temperature fluctuations, ensuring stable and efficient motor drive.

2. Industrial automation and servo drives: They provide reliable filtering and energy storage, ensuring precise control in complex factory environments such as high temperatures and dust.

3. Photovoltaic inverters and energy storage systems (ESS): They withstand extreme outdoor temperatures (both cold and hot), providing stable support for renewable energy conversion.

4. Electric vehicle charging stations (OBCs): They meet the temperature, life, and reliability requirements of automotive applications (select models are AEC-Q200 certified), contributing to green transportation.

5. Telecommunications power supplies and server power supplies: They meet the demands of high power density and high-frequency switching, ensuring stable power supply for data centers and network equipment.

6. Other power electronic equipment requiring high reliability: such as UPS (uninterruptible power supplies) and medical equipment power supplies.
