## Parasitics and Capacitor Selection, Part VIII: Voltage Coefficient for Class II Ceramic Capacitors

General decoupling applications require capacitors with a combination of high capacitance and low reactance (i.e., low equivalent series resistance [ESR] and equivalent series inductance [ESL]) in the circuit. The trend in digital applications for greater data Continue Reading...

## Parasitics and Capacitor Selection, Part 7: Ripple Ratings and Self-Heating

In this segment, we’ll discuss ripple ratings — or how to cook a Continue Reading...

## Parasitics and Capacitor Selection, Part 6: Capacitance

Since we’re now halfway through the series, it’s probably a good time to look at the nameplate parameter for capacitors – the capacitance Continue Reading...

## Innovative Single Contact Solutions in Renewable Energy & Smart Grid

Electronic equipment and power management is becoming increasingly critical as our power grid ages and renewable energy comes on line. In response, new technologies are being developed to protect equipment from power disturbances and Continue Reading...

## Parasitics & Capacitor Selection, Part 5: Q

Q is a dimensionless number. It represents the ratio of the maximum energy stored to the power loss in a system at a given angular frequency, rather than the inverse Continue Reading...

## Parasitics & Capacitor Selection, Part 4A: Dissipation Factor

This month, we'll look at dissipation factor, and we'll lay the groundwork for next month's blog about Continue Reading...

## Parasitics & Capacitor Selection, Part 4B: Dissipation Factor

Since capacitance bridges measure capacitance using a small AC signal voltage, it is possible to measure DF Continue Reading...

## Parasitics & Capacitor Selection, Part 3: Dielectric Absorption (DA)

Parasitics often play a greater role in determining a capacitor's suitability for an application than the capacitance value of the part itself. This series looks at how some of these parasitics affect capacitor selection. This month, we'll examine dielectric Continue Reading...

## Parasitics & Capacitor Selection, Part 2D: Equivalent Series Resistance (ESR)

In ceramic capacitors, the dielectric effects outweigh the electrode and termination conductivity, as Class 1 dielectrics have lower ESR and experience the least change with frequency and temperature, so their ESR only drops slightly with increasing Continue Reading...

## Parasitics & Capacitor Selection, Part 2C: Equivalent Series Resistance (ESR)

In pulse applications, capacitors will significantly extend the batteries’ lifetime, as well as allow the circuit to operate over a much wider temperature Continue Reading...
