One common trend in switch-mode power supplies, microprocessors, and digital circuit applications is reduced noise at higher operating frequencies. In order to make this possible, components with low ...

Wet tantalum capacitors now use the intrinsic capability of a proprietary cathode system to provide high capacitance/voltage characteristics, allowing them to be qualified to DSCC 93026. The Next ...

A lithium-ion capacitor (LIC) is a hybrid type of capacitor out of the family of the supercapacitors. Activated carbon is used as cathode. The anode of the LIC consists of carbon material which is pre ...

Ever wonder what’s inside an electrolytic capacitor? Many of us don’t, having had at least a partial glimpse inside after failure of the cap due to old age or crossed polarity. The rest of us will ...

When used in the design of flexible lithium-ion capacitors, dual metal sulfides-ZnS/CuS show a noticeable improvement in electrochemical stability and performance over transition metal sulfides and ...

Tantalum capacitors offer designers of densely packed, high-performance electronic circuits a reliable high-capacitance solution with stable performance. A historical favorite among design engineers, ...

Download this article in PDF format. The RF PIN diode as we know it today was invented by J. Nishizawa in 1950. Now, almost 70 years later, a new PIN diode concept—shielded-anode PIN diode (SAPIN)—has ...
