Technical Article: Predicting Metal Film Capacitor Lifetime Using Thermal Simulation

Predicting Metal Film Capacitor Lifetime Using Thermal Simulation Written By: Youssef Laamimat Abstract: In high-power applications like electric vehicles (EVs), customized metal film capacitors are often required to meet energy demands in a specific form factor. These capacitors exhibit a strong temperature dependence of their bulk capacitance over time, which directly limits their total service life. To maximize lifetime while minimizing space requirements, it is important to include accurate thermal simulation as part of the design process to ensure optimized and evenly distributed heat generation.

Technical Article: SuperCapacitors: A Reliable Backup Power Solution

SuperCapacitors: A Reliable Backup Power Solution Written By: Johnson Jiang Abstract: Electric double-layer capacitors (EDLCs) are electrochemical capacitors called “SuperCapacitors,” or supercaps, due to their high energy density. Compared to traditional electrolytic capacitors, SuperCapacitors store electrical energy about two to three orders of magnitude higher and achieve several hundred thousand to millions of charge-discharge cycles. This advantage comes from the special construction of SuperCapacitors.

Technical Article: Electrostatic Protection Using Ceramic Capacitors

Electrostatic Protection Using Ceramic Capacitors Written By: Oliver Zimmermann | John McCarry Abstract: Any conductive interface between an electrical circuit and the outside world introduces the possibility of damage through electrostatic discharge (ESD). Accumulated static charge on a person, a cable, or any similar surface can readily dissipate its stored potential energy upon contact into sensitive components resulting in highly destructive currents. Ideally, varistors and TVS diodes only activate to protect the circuit when a high voltage is present and impart no parasitic effects during normal operation. For high-speed data lines, in particular, it is critical that the protection device introduce as little capacitance as possible (Electronic Design). TVS diodes and varistors are therefore specified not only by their voltage

Advantages of Varistors and Their Applications in the Automotive Field

Advantages of Varistors and Their Applications in the Automotive Field

Advantages of Varistors and Their Applications in the Automotive Field Written By: George Zhang Abstract: Multilayer chip varistors (MLVs) are resistive elements comprising zinc oxide (Zn0) as the main component. In recent decades, they are being used for protection against surge voltage, noise, and transient voltages. Unlike conventional varistors, the maximum peak current and non-linear coefficients are large, and the resistance is very high below a threshold voltage, hardly allowing current to flow. However, when the voltage exceeds the threshold, the resistance drops abruptly and allows a large current to flow. Such properties make MLVs ideal as protective elements in a host of electrical and electronic applications, including automobiles

Harvest energy from sensors for reduced maintenance and improved safety

There are many places you could implement energy-harvesting (EH) sensors in factory automation and measurement applications. For example, remote or hard-to-access applications that currently rely on physical equipment inspections for status updates could be converted to a wireless sensor network, provided that there is enough energy nearby to capture and that the measurements are sufficient for making an informed decision.
