The Basics & Benefits of Tantalum & Ceramic Capacitors

By Power Systems Design Posted On 13.12.2018

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 and Induction Heating Capacitors

By Capacitor Faks Posted On 11.12.2018

Source: EPCI, Capacitors Faks blog

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 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…)

Five not-so-general-purpose multilayer ceramic capacitors

By Capacitor Faks 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…)

Lorandt explains the influence of the ESR on the voltage ripple at the output of a buck converter. For this purpose, he measures the output voltage of three identically constructed buck converters. Only the output capacitor is different on each converter – Aluminum electrolyte, Aluminum polymer or MLCC. (more…)
