6 FAQs about [Capacitor DC voltage marking]

What are the markings on a capacitor?

Capacitors are labeled in a wide variety of different ways, but this handout lists the most common markings on capacitors and what they mean. Electrolytic and Tantalum capacitors often have the capacitance (in uF) and voltage (maximum allowed voltage) printed on them in human-readable form.

How do you know if a capacitor is good?

Check the voltage rating. If there is room on the body of the capacitor, the manufacturer usually lists voltage as a number followed by a V, VDC, VDCW, or WV (for "Working Voltage"). This is the maximum voltage the capacitor is designed to handle. 1 kV = 1,000 volts.

How to identify a capacitor?

Thus, for such concise markings many different types of schemes or solutions are adopted. The value of the capacitor is indicated in “Picofarads”. Some of the marking figures which can be observed are 10n which denotes that the capacitor is of 10nF. In a similar way, 0.51nF is indicated by the marking n51.

What is a voltage rating on a capacitor?

Chart1: CAPACITOR MARKING CODE STANDARDIZED BY THE ELECTRONIC INDUSTRY ALLIANCE (EIA) The voltage rating on a capacitor indicates the maximum voltage it can safely handle. This parameter is ensuring safety and performance, as it prevents over-voltage failures that can damage both the capacitor and the surrounding circuitry.

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 do you mark a capacitor?

The markings on the capacitors can also be done by printing it on the capacitor. This is true for capacitors which provide enough space for marking to be printed and include film capacitors, disc ceramics, and electrolytic capacitors.
