by Pierre Mars, Vice President, Quality & Applications Engineering, CAP-XX (Australia) Pty Ltd

CAP-XX announced its 3V thin prismatic cells, suitable for slim form factor applications, that can be connected directly across a 3V battery. This has reduced cost and space and extends battery run time compared to placing a 2.7V regulator between the battery and a lower voltage conventional 2.7V supercapacitor. The article introduces the 3V supercapacitor’s characteristics and behaviour at the end applications. (more…)

How to Choose the Right Inductor for DC-DC Buck Applications

By AZO Sensors, TT Electronics Posted On 22.5.2019

Source: AZO Sensors, TT Electronics article

DC-DC converters of different varieties are widely used in markets such as telecommunications, automotive, medical (portable), and industrial. The ‘buck’ DC-DC converter is employed to step voltages down without isolation and utilizes an inductor as an energy storage element. This article will explain how to choose the correct inductor for optimum performance. (more…)

Film Capacitors Characteristics and Uses in Power Applications

By EDN Posted On 18.4.2019

Source: EDN article

by Rudy Ramos.

Engineers designing power electronics find that capacitors are needed for several functions, from energy storage to filters and decoupling. Different capacitor types are available, that at first sight might seem equivalent in their headline ratings of capacitance and voltage, but would not perform equally. Incorrect selection can lead to, at best, an expensive ‘over-engineered’ solution and, at worst, an unreliable or unsafe product. (more…)
