Meeting the safety requirements of the new 3C regulations: Analyzing the key role of YMIN polymer hybrid aluminum electrolytic capacitors in mobile power supplies
Recently, the State Administration for Market Regulation has launched a large-scale recall of mobile power supplies without 3C logos/unclear logos, and more than 500,000 products have been removed from the shelves due to safety hazards.
Manufacturers use inferior battery cells, which frequently lead to problems such as overheating, false power, and sharp reduction in life of mobile power supplies. Therefore, high-reliability components that meet the new 3C regulations are becoming the ultimate decisive factor in the safety and efficiency of mobile power supplies.
01 YMIN polymer hybrid aluminum electrolytic capacitors
In the mobile era of pursuing extreme portability and long-lasting battery life, mobile power supplies have become an indispensable partner. However, mobile power supplies still have high standby power consumption, heat, and inconvenience in carrying, which affect user experience and even safety.
YMIN polymer hybrid aluminum electrolytic capacitors accurately solve these problems and create significant value for mobile power supplies:
Low leakage current:
The power of the mobile power supply is quietly lost when it is idle and standby, and the power is insufficient when it is used. YMIN polymer hybrid aluminum electrolytic capacitors have extremely low leakage current characteristics (can be as low as 5μA or less), which effectively suppresses the self-discharge of the device when not in use. It truly realizes the “take it and use it, long-lasting standby” of mobile power.
Ultra-low ESR:
YMIN polymer hybrid aluminum electrolytic capacitors have ultra-low ESR and extremely low self-heating characteristics. Even under the large ripple current conditions brought by fast charging, it is far better than the serious self-heating problem of ordinary capacitors under high ripple. It greatly reduces the heat generation when the mobile power is used, and reduces the risk of bulging and fire.
High capacity density:
When designing mobile power to achieve high capacity, it often leads to excessive volume, which becomes a travel burden. Under the same volume, the capacity value of polymer hybrid aluminum electrolytic capacitors can be increased by 5%~10% compared with traditional polymer solid aluminum electrolytic capacitors; or under the premise of providing the same capacity, the capacitor volume is significantly reduced. Make mobile power easier to achieve miniaturization and thinness. Users do not need to compromise between capacity and portability, and travel without burden.
02 Selection recommendation
Conclusion
YMIN polymer hybrid aluminum electrolytic capacitor technology brings core value to mobile power supply through its higher capacity density, excellent heat dissipation performance and ultra-low leakage current. Choosing a solution equipped with polymer hybrid aluminum electrolytic capacitors is not only choosing a key component, but also choosing to provide mobile power users with a safer, more convenient and more lasting experience.
