WhatAreCaps.png

In really simple terms, a capacitor is a passive two-terminal electrical component used to store energy electrostatically in an electric field. A capacitor holds a charge, similar to how a bucket holds water. The world's first capacitor was in the shape of a jar and was named the Leyden jar. Invented in the 18th century, it was a glass jar coated with metal on both the inside as well as the outside, with the glass acting as the dielectric.  Read more...

The resistor is the most common and well-known of the passive electrical components.  A resistor resists or limits the flow of electric current in a circuit. There are many uses for resistors: they are used to drop voltage, limit current, attenuate signals, act as heaters, act as fuses, furnish electrical loads and divide voltages.  Read more...

The demands of the space segment differ from the commercial segments in one major area — ongoing reliability. ES Components is franchised to sell components for space applications.  The manufacturers that we represent offer both active and passive components.  Read more...


 
 

This is a handy table that makes it easier to convert capacitance values between picofarads, nanofarads, and microfarads.  It also explains Vishay's three digit encoding system for MLCC capacitor part numbers. Read more...


 
 

There are many control-system applications where the accurate measurement of current flow is required.  In many of these applications the measurement circuits must provide accurate feedback of system current flow(s) across a very broad range of operating temperatures.  Components in these applications require a minimal absolute temperature coefficient variation to ensure accurate feedback and efficient control system operation.  Read more...
