01 Development of automotive central control instrument panel

Because of the increasing adoption rate of advanced driver assistance systems, the continuous expansion of the automotive instrument panel market, and the increasing popularity of connected cars. In addition, the increasing application of advanced driver assistance systems (ADAS) has promoted innovation in the automotive instrument panel market, thereby enhancing the design and functionality of display screens. Integrating ADAS functions into the instrument panel can improve safety and enhance the driving experience.

02 Function and working principle of the central control instrument panel

The instrument panel tachometer works according to the magnetic principle. It receives the pulse signal generated when the primary current in the ignition coil is interrupted. And converts this signal into a displayable speed value. The faster the engine speed, the more pulses the ignition coil generates, and the greater the speed value displayed on the meter. Therefore, a capacitor is needed in the middle to filter the effect and lower the ripple temperature rise to ensure the stable operation of the instrument panel.

03 Automobile central control instrument panel – capacitor selection and recommendation

04 YMIN capacitors provide perfect protection for the central control instrument panel of the car

YMIN solid-liquid hybrid aluminum electrolytic capacitors have the characteristics of small size (thinness), large capacity, low ESR, resistance to large ripple current, impact resistance, and strong shock resistance. On the basis of ensuring the stable operation of the central control instrument panel, they are thinner and smaller.
