Abstract: Shanghai Yongming Electronic expanded its conductive polymer hybrid aluminum electrolytic capacitor line with launching of VHT series which is rated at 4000hrs at 125℃, targeting the automotive sector. The series is highly advanced series from VGY series 105℃ 10000hrs and all the products are meet AEC-Q200.
Content: With the growing demand of eco-friendly cars, high efficiency, energy saving and zero emissions, vehicles are rapidly shifting from gasoline engine to hybrid vehicles and electric vehicles. Many countries have actively introduced relevant industrial policies and regulations to improve the electric vehicle industry chain, accelerate the promotion of electric vehicles, and promote low-carbon and environmentally friendly travel. The electrification era has coming in automotive industry and being an irreversible trend. A recent report released by Strategy, a consulting agency under PricewaterhouseCoopers, predicts that by 2030, the number of new electric vehicle registrations in the EU, the United States and China will exceed 17.4 million in the world’s three major automotive markets.
Under this circumstance, the 48V MHEV system with competitive cost, relatively obvious fuel-saving effect, and little change to the existing vehicle structure has become a new hot spot in the industry.
In the early days liquid electrolytic capacitor has played an important role in DC circuit. With the development of liquid electrolytic capacitor technology and the emergence of polymer solid capacitor, Hybrid electrolytic capacitor is optimal for high-stability and high-power automotive applications, not only in smaller and smaller size but also maintained voltage in a considerable level, as well as providing a high ripple current capacity.
YMIN polymer hybrid capacitor with miniature size and LOW ESR
YMIN expanded its conductive polymer hybrid aluminum electrolytic capacitor line with launching of VHT series which is rated at 4000hrs at 125℃, targeting the automotive sector. The series is highly advanced series from VGY series 105℃ 10000hrs and all the products are meet AEC-Q200.
The VHT series offers a capacitance range of 6.8 μF to 470 μF, with rated voltages from 16 V to 80 V. Package sizes range from 5*5.8mm to 10*10.5mm and a lower ESR down to 16 m?, with a ripple current of 2.3 Arms. This series has been widely used in automotive control, power strain applications and LED lighting These products can also be used in replacing of larger MLCCs, aluminum electrolytic capacitor, or tantalums.
ESR is one of the critical parameter for polymer hybrid capacitor in control unit which is directly effecting the temperature rise and ripple capacity.
Hybrid capacitors utilize combination of liquid electrolyte and solid polymer material rendering a high ripple current capacity with small size and high voltage.
YMIN Conductive Polymer Hybrid Capacitor Series
Other than VHT series, YMIN also has its initial SMD polymer hybrid series VHR 2000hours life under 150℃.
These capacitors are widely used in motor control, 48V inverters, power supply, audio amplifier, car LED lighting, welding, aerospace, telecom ect.,
