6 FAQs about [Capacitor Rated Capacity Table]

How are capacitors rated?

Capacitors are rated according to how near to their actual values they are compared to the rated nominal capacitance with coloured bands or letters used to indicated their actual tolerance. The most common tolerance variation for capacitors is 5% or 10% but some plastic capacitors are rated as low as ±1%.

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 happens if a capacitor exceeds rated voltage?

Capacitors have a maximum voltage, called the working voltage or rated voltage, which specifies the maximum potential difference that can be applied safely across the terminals. Exceeding the rated voltage causes the dielectric material between the capacitor plates to break down, resulting in permanent damage to the capacitor.

How to choose a capacitor?

A capacitor with an appropriate ripple current and working voltage rating should be chosen. Polarity and Reverse Voltage – If an electrolyte capacitor is used in the circuit, it must be connected in the correct direction. Its reverse voltage rating should be at least twice the possible reverse voltage in that branch of the circuit.

What does voltage rating mean on a polarized capacitor?

The voltage rating indicates the maximum voltage the capacitor can handle, marked as a number followed by "V". Tolerance shown as a percentage, indicating how much the actual capacitance can vary from the marked value. Polarized capacitors will have a plus (+) or minus (-) sign, or a stripe indicating the negative leg. 3.

What is a tolerance rating for a capacitor?

As with resistors, capacitors also have a Tolerance rating expressed as a plus-or-minus value either in picofarad’s (±pF) for low value capacitors generally less than 100pF or as a percentage (±%) for higher value capacitors generally higher than 100pF.
