When selecting capacitors for automotive electronics, this essential knowledge is a must!

To select reliable capacitors for today's automotive electronic applications, it is essential to understand the performance characteristics of various capacitors and the operating conditions in different applications. Compared to the specifications in datasheets, the operating environment in applications has a significant impact on the actual circuit performance, making it crucial for determining the optimal cost-performance solution. Figure 1 illustrates the typical capacitance and voltage ranges of commonly used capacitor dielectrics, often with several overlapping options. While capacitance and voltage are usually the primary considerations...

Challenging high humidity and high temperatures, which DC-Link capacitor can come out on top?

In power electronics applications, the DC-Link capacitor is an indispensable component. Its function is to utilize the characteristics of capacitors to store and release electric charge, thereby balancing the current and voltage in the circuit and stabilizing the system's operation. With the development of renewable energy, the application scenarios for DC-Link capacitors are becoming increasingly diverse. They are essential in fields such as photovoltaic inverters, new energy vehicles, charging stations, and UPS systems.

Advantages of tantalum capacitors in ignition systems

For modern detonation systems, molded tantalum (MnO2) capacitors offer two main advantages. First, unlike aluminum electrolytic capacitors, they provide the high capacitance required by these compact systems. Second, unlike multilayer ceramic chip (MLCC) capacitors, tantalum capacitors exhibit excellent stability under voltage, temperature, and mechanical stress. Vishay offers a complete range of molded chip solid tantalum capacitors with capacitance values ranging from 0.1 μF to 1.

Reflective sensors simplify the design of photoelectric switches.

This article introduces how to leverage the advantages of reflective sensors to simplify and improve the design of miniature optical sensors. Reflective sensors are valuable tools for designing miniature optoelectronic switches. They are compact and intuitive, making them ideal for simplifying human-machine interaction. These sensors are often hidden behind infrared (IR) lens covers, and they respond quickly when a finger or other object touches the surface of the lens cover. Optical sensors or reflective sensors can be used to streamline the design process.

Battery management system that meets functional safety requirements

In today's world, where environmental awareness is growing, the automotive industry is undergoing changes. Tasks that could only be accomplished by internal combustion engines in the past will, in the future, be handled by vehicles powered by hybrid systems, electricity, or even fuel cells. In the past, many manufacturers focused on the mechanical components essential for traditional internal combustion engines and transmission systems. Moving forward, the focus will shift to other components. They may develop new types of solid-state batteries to increase driving range and the number of charge-discharge cycles, which current lithium batteries cannot achieve.
