Technical Article: Analysis of the DC Blocking Capacitor for Stereo High-Fidelity Audio

Analysis of the DC Blocking Capacitor for Stereo High-Fidelity Audio Written By: Rick Liu Abstract: The representation of audio signals in analog and digital electronics can take many forms. Still, they must ultimately be converted back to their mechanical origins as the motion of air molecules propagating as waves. These waves are generated by moving a mass, often the cone of a speaker, back and forth around a neutral position. As such, any fixed offset in the audio signal, represented by a DC bias, is simply a waste of energy and possibly a source of imbalance in the resulting sound wave. Series blocking capacitors are generally used for each audio channel to eliminate the potential of any DC component. While

Technical Article: Variability and Tolerance of Ceramic Capacitors

Variability and Tolerance of Ceramic Capacitors Written By: Robert Lu Abstract: The multi-layer ceramic capacitor (MLCC) is one of the most common capacitor varieties found in electronic design. It offers a wide range of bulk capacitance and voltage tolerance in numerous form factors at relatively low cost. While these devices have become commonplace in the designers’ tool chest, they exhibit some often overlooked peculiarities. Of primary concern is the sensitivity of effective capacitance to several environmental factors, including temperature, applied bias voltage, and age. If these factors are unaccounted for, the risk of product failure becomes very real, especially in manufacturing variability and overall tolerance stack-up.

Platform Structure Clock Oscillators Written By: Toshihiko Koyanagi Abstract: Numerous devices in people‘s lives today are becoming more sophisticated. As a result, the number of crystal devices installed is increasing. For example, with the evolution of autonomous driving, we are using crystal devices for many functions such as sensor systems to detect distance, camera systems to capture images, image processing systems to process captured images, and communication systems to communicate many of those digital data in and out of the vehicle at high speed. In addition, in the network market, the number of crystal devices is increasing along with the further increase in the speed of communication devices, as well as the increase in the frequency and precision.

Aluminum Electrolytic Capacitor Performance and Circuit Impacts

On January 11, 2023 / Media Coverage, News / Events / Press

A growing number of applications, ranging from solar power converters all the way to miniature power supplies for highly complex processing cores, are starting to capitalize on the benefits of aluminum electrolytic capacitors. Aluminum electrolytics are also increasingly used to satisfy miniaturization demands in complex power tree applications like FPGAs powered by multiple voltages. And while it’s true that aluminum electrolytics also come with disadvantages, several of the more well-known ones are no longer true, and other perceived disadvantages can be reduced or eliminated by selecting newer components engineered to overcome some of the technology’s traditional shortcomings.

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.

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.
