Kemet Corporation – Capacitor Technologies

KEMET’s product line includes surface-mount capacitors in aluminum, ceramic and tantalum and leaded capacitors in ceramic and tantalum.

Kemet Corporation – Capacitor Technologies

Broad selection of capacitor technologies in the industry across all dielectrics, along with an expanding range of electromechanical devices, electromagnetic compatibility solutions and super capacitors.

The name “KEMET” is a blend of the words “chemical” and “metallurgy.”

“…..Fortunately for KEMET, Bell Laboratories had also invented the solid tantalum capacitor, which complemented the use of low-voltage transistors (semi-conductors) in electrical circuits. Since Union Carbide had experience in the fields of high-temperature metals and alloys, the solid tantalum capacitor was chosen as KEMET’s “new product”.

Kemet High Voltage C0G FT-CAP

High Voltage C0G FT-CAP

The HV C0G FT-CAP is ideal for a broad range of high voltage applications in which high volumetric efficiency and resistance to thermal and board stress are critical.

It offers low leakage current, exhibits low ESR at high frequencies and finds conventional use as snubbers or filters in applications such as switching power supplies and lighting ballasts. Their exceptional performance at high frequencies has made them a preferred choice of design engineers worldwide.

Vishay – Discrete Semiconductors and Passive Components

“In the 1950s, patents were issued for the PhotoStress products developed by Dr. Felix Zandman. These products reveal and measure stress distribution in airplanes, cars, and other structures under live load conditions. …..

Dr. Zandman, with the financial support of Alfred P. Slaner, founded Vishay in 1962 to develop and manufacture Bulk Metal foil resistors. The Company was named after the village in Lithuania ……..” Vishay History

JTIsoft Modeling Overview

 JTIsoft Modeling Overview

MLCsoft and MLIsoft provide highly detailed graphical plots of device performance data in two basic formats over a user specified frequency range. The chart displays are instantly updated as the user makes capacitance or frequency changes. Smith chart displays of both impedance and S11/S22 are available as point plots, line plots, and line-point plots.
