The new Request for Electric Vehicles Lights and the best capacitor choice

Industry development and product upgrade of automotive smart lights

1. Industry development:

With the rise of car interconnection and automatic driving, car lighting is also gradually becoming intelligent. Car lights, as visual and safety components, are expected to become the core carrier of vehicle data stream output, realizing the functional upgrade from "function" to "smart".

2. Product upgrade:

a. Miniaturization and thinning: The miniaturization of automotive lighting can effectively reduce the installation space and weight, thus adding more flexibility to the shape of the car.

b. The intelligentization of automobiles has increased the application of lighting systems, which requires many electronic components to be integrated and coordinated with each other to achieve new lighting functions, such as "light navigation, width display light carpet" and so on.

Requirements for

capacitorin smart car lights

Filtering and anti-interference in a wide frequency range:

Dozens of light-emitting LEDs are used in car lights, so their operating current is larger. High current is accompanied by greater ripple disturbance and voltage fluctuation. At this time, the capacitor is required to be low and stable in the wide frequency (10KHZ-800KHZ) range. ESR, to filter out as much line ripple noise as possible to ensure stable system operation.

Low temperature rise:

The main factor affecting the lighting effect and life of LED cars is temperature. Therefore, capacitors are required to have low and long-term stable ESR and electrostatic capacitance. Low ESR ensures that capacitors can maintain low ripple temperature rise when large ripple currents pass through.

Miniaturization and thinning:

The miniaturization and thinning of automotive lighting has become an unstoppable development trend in the automotive industry, and the miniaturization and thinning of capacitors will help the miniaturization and thinning of automotive lights.

Smart vehicles lights - YMIN solid-liquid hybrid capacitor advantages and selection recommendations

l The capacitance value of the capacitor at a low temperature of -55°C can retain more than 90% of the normal temperature value, and the

capacitance

value of the capacitor at a high temperature of 125°C does not exceed 1.1 times of the normal temperature value

l In the range of 10KHz~600KHz, the ESR of the capacitor remains relatively stable and relatively low, so it can filter out line clutter and noise in a wide frequency range to ensure stable operation of the whole machine.

l After long-term high-temperature operation at 105°C, the capacitance of the capacitor can still maintain more than 85% of the initial value, and its ESR does not exceed 1.5 times the specified value.
