Exhaust fans are key equipment for ventilation and heat dissipation in industrial, automotive and home environments. The stability of their motor start-up and operation is directly related to the life and energy efficiency of the equipment. With its unique technical advantages, YMIN capacitors provide efficient and durable capacitor solutions for exhaust fans, significantly improving the performance of the entire machine.
Stable guardian in harsh environments
Exhaust fans often face complex working conditions such as high temperature, oil pollution, and dust. YMIN’ssolid-liquid hybrid capacitors (such as the VHT series) have a long life of 4000 hours at 125°C, and the capacity change rate does not exceed -10%, and the ESR value is stable within 1.2 times the initial value, effectively resisting high temperature aging. Its wide temperature resistance characteristics (-55℃~125℃) can adapt to the extreme temperature difference from the cold garage to the high-temperature engine compartment, ensuring that the capacitor parameters do not drift.
Power guarantee for instant start
The exhaust fan motor needs to withstand high-rate current shock when starting. YMIN capacitors have a single-cell impact current resistance of more than 20A, which can provide instantaneous high current for the motor to avoid startup delay or stalling. At the same time, its ultra-low ESR (minimum 3mΩ) can reduce current loss, suppress ripple noise, make the motor run more smoothly, and reduce the risk of abnormal noise.
Long-life maintenance-free design
Traditional electrolytic capacitors are prone to dryness and failure under frequent charging and discharging. YMIN uses polymer mixed electrolyte technology, combining the advantages of solid and liquid electrolytes to achieve an ultra-long life of 10,000 hours at 105°C, which is more than 3 times higher than ordinary capacitors. For example, its automotive-grade products have passed the AEC-Q200 certification and IATF16949 system, meeting the demand for free replacement of automotive exhaust fans for ten years, greatly reducing maintenance costs.
Balance between miniaturization and safety
For compact exhaust fan structures, YMIN’slaminated polymer solid capacitors (such as the MPD series) achieve high capacity density (such as 16V/220μF) through thin design (minimum size 7.3×4.3×1.9mm), saving 40% of installation space. Itssolid-state structureeliminates the risk of leakage, and through anti-vibration design (compliant with AEC-Q200), it prevents the capacitor from falling off or short-circuiting due to bumps in the vehicle exhaust fan.
Conclusion
YMIN capacitors, with the triple advantages of “impact resistance, long life, and small size”, solve the pain points of exhaust fans in start-stop impact, high temperature aging, and space limitations, and provide silent, efficient, and zero-maintenance ventilation power support for industrial equipment and automotive systems. Its technical core is redefining the reliability standards of electromechanical components and promoting the iterative upgrade of traditional ventilation equipment to intelligence and durability.
