YMIN Capacitors, the High-Performance Guardian of Power Bank Cells

In the power bank industry, battery cell performance and safety are crucial, and the choice of capacitors directly impacts overall device performance. YMIN capacitors, with their unique technological advantages, have become a core component in high-end power bank cell management, significantly improving the user experience.

YMIN’s polymer hybrid aluminum electrolytic capacitors feature extremely low leakage current (down to below 5μA), effectively suppressing self-discharge when the device is not in use. This solves the pain point of silent power loss when the power bank is idle, enabling true “on-the-go, always-on” readiness.

Their ultra-low ESR (equivalent series resistance) ensures extremely low heat generation. Even under high ripple current conditions (such as fast charging), they significantly reduce the severe self-heating issues associated with conventional capacitors. This significantly reduces heat generation during power bank use, minimizing safety hazards such as bulging and fire.

In space-constrained power bank designs, YMIN capacitors offer significant advantages in high capacitance density. Within the same volume, their capacitance can increase by 5% to 10% compared to traditional polymer solid aluminum electrolytic capacitors, making products easier to miniaturize and thin, eliminating the need to compromise between capacity and portability.

YMIN’s VPX series and other products also feature high reliability, low ESR, and high ripple current tolerance. They also offer a wide operating temperature range (-55°C to 105°C) and a 2,000-hour lifespan even at 105°C, ensuring stable operation of power banks in a variety of harsh environments.

Internationally renowned brands such as Xiaomi have adopted YMIN capacitors in their fast-charging power banks, fully demonstrating their product performance and recognition as a top-tier international brand. These capacitors are typically used for input and output filtering in power banks, helping to stabilize voltage, purify current, and improve overall charging and discharging efficiency.

With the State Administration for Market Regulation implementing the new 3C regulations for power banks, higher requirements have been placed on the reliability and safety of components. YMIN capacitors, with their superior performance, help power bank manufacturers meet these new regulations, providing users with a safer, more convenient, and longer-lasting user experience.
