What is the working voltage of a capacitor?
The Working Voltage is another important capacitor characteristic that defines the maximum continuous voltage either DC or AC that can be applied to the capacitor without failure during its working life. Generally, the working voltage printed onto the side of a capacitors body refers to its DC working voltage, (WVDC).
How to find the value of electrolytic capacitors?
It is easy to find the value of electrolytic capacitors because they are clearly printed with their capacitance and voltage rating. The voltage rating can be quite low (6V for example) and it should always be checked when selecting an electrolytic capacitor.
What are the basic parameters of a capacitor?
This article explains some basic parameters of capacitors – insulation resistance, DCL leakage current and breakdown voltage / withstanding voltage. Important feature of capacitor apart its capacitance is: its ability to keep the charge for some time without self-discharging due to its internal leakage (conductivity) mechanisms.
What is the voltage rating of an electrolytic capacitor?
Fig 1 : Electrolytic capacitor with capacitance value, voltage rating and terminal marking. The voltage rating of a capacitor, expressed in volts (V) or WVDC (Working Voltage Direct Current), represents the maximum voltage the capacitor can safely handle without breaking down or experiencing electrical breakdown.
What are the most important capacitor specifications?
Some of the most important capacitor specifications are mentioned below : Capacitance is the fundamental property of a capacitor and is measured in Farads (F). It determines the amount of electrical charge a capacitor can store per unit voltage. Higher capacitance values indicate a greater ability to store charge.
Are DC & AC voltage values the same for a capacitor?
DC and AC voltage values are usually not the same for a capacitor as the AC voltage value refers to the r.m.s. value and NOT the maximum or peak value which is 1.414 times greater. Also, the specified DC working voltage is valid within a certain temperature range, normally -30°C to +70°C.
