by Brian Brunette, AVX Corporation

Tantalum (Ta) capacitors and multilayer ceramic capacitors (MLCCs) are two widely accepted capacitor technologies that can be employed in a wide range of electronics applications. Although both technologies perform the same basic function, they are very different in terms of their construction techniques, materials, and performance under various conditions, so it’s important to understand the potential impact of selecting one over the other.

Induction heating occurs when an electrically conducting material is placed within a varying magnetic field. The heating is due to eddy-current losses within the material (in magnetic materials such as iron, some heat is also generated by hysteresis losses). Let’s have a look at needs for capacitors in this application field. (more…)

by Anthony Kenny, Capacitor Faks

Lasers nowadays are one fabrication tool among many for industrial production, measuring and testing applications. Industrial lasers commonly employ a pulse grade capacitor to generate and deliver the energy required to test, measure or make the product or service on offer. In this article, we examine the importance of the self-healing characteristics of metallized film dielectrics used in pulse grade capacitors for industrial laser applications. (more…)

by Johanson Technology.

For many high power RF applications, the ‘Q factor’ of embedded capacitors is one of the most important characteristics in the design of circuits. This includes products such as cellular/telecomm equipment, MRI coils, plasma generators, lasers and other medical, military and industrial electronics. (more…)

Choosing the right blocking capacitors

Any engineer knows that capacitors are a fundamental building block in RF/microwave systems. Bypass networks are one example—they require capacitors to bypass ac signals to ground. For such cases, rules-of-thumb or approximate equations can be used to select the best capacitor for the job. However, those approaches may not always be valid. In the technical paper, “Choosing blocking capacitors – it’s more than just values,” Knowles Precision Devices discusses real-world capacitor performance and then presents measurement results of various capacitor bypass networks.

Five not-so-general-purpose multilayer ceramic capacitors

Tomáš Zedníček Posted On 1.11.2018

Source: Capacitor Faks blog

The MLCC capacitor is one of the most widely used passive components today. Approximately 1000 billion multilayer ceramic capacitors are produced per year. Manufacturers have improved the electrical performance of these passive components through incremental progress in design, manufacturing methods, and materials. Today’s chip MLCC capacitors are smaller and offer better reliability and improved electrical specifications as compared to their predecessors. They offer impressively high capacitance values, high temperature values (over 200oC), and ultra-low loss. Furthermore, today’s surface mount MLCC capacitors have higher capability to withstand thermal expansion and bending. (more…)

Until CAP-XX announced its 3V range of prismatic cells, 3V cells were only available in cylindrical cans due to the more robust construction of cans enabling a wider choice of materials inside the supercapacitor. CAP-XX has determined a set of materials that have good capacitance, ESR, temperature and life performance at 3V in a thin prismatic package. (more…)
