6 FAQs about [What are the parameter identifications of capacitors ]

What does proper termination mean in a capacitor?

In the context of a capacitor, proper termination means matching the characteristic impedance (Z0). This is not the same as matching the device being tested (DUT). If the DUT generates a reflection when properly matched, that is considered part of the reflection produced by the device, the S11 you are trying to measure, so you don't want to suppress it.

How is the capacitance of a capacitor measured?

The capacitance of a capacitor is measured in pico-Farads (pF), nano-Farads (nF) or micro-Farads (μF). The nominal value of the Capacitance, C, is the most important of all capacitor characteristics and is marked onto the body of the capacitor as numbers, letters or coloured bands.

What is the first step in understanding a capacitor label?

The best way to figure out which capacitor characteristics the label means is to first figure out what type of family the capacitor belongs to whether it is ceramic, film, plastic or electrolytic.

What parameters should you consider when choosing a capacitor?

Voltage This is one of the key parameters to consider when selecting a capacitor for your application. For most types of capacitors, manufacturers specify voltage characteristics in terms of rated voltage, surge voltage, operating voltage, transient voltage, reverse voltage, and ripple voltage.

What is a capacitor used for?

A capacitor is one of the basic circuit components in electrical and electronic circuits. Capacitors are used to store energy in the form of an electrostatic field. Capacitors are available in several different types and sizes. Each type of capacitor has its unique characteristics and specifications that impact its performance.

What happens to a capacitor's capacitance in extreme temperatures?

If the air or surrounding temperature becomes too hot or too cold, the capacitance value of the capacitor may change so much as to affect the correct operation of the circuit. Changes in temperature around the capacitor affect the value of the capacitance because of changes in the dielectric properties.
