Capacitance tolerance is indeed important in most electronic circuits and applications. While it may seem harmless to ignore this specification, it can significantly impact circuit performance and functionality in precision circuits …
Capacitor tolerance refers to the allowable deviation from the stated capacitance value. It’s expressed as a percentage and indicates how much the actual capacitance can vary from the marked value. For example, a capacitor with a 10% tolerance and a marked value of 100µF could have an actual capacitance anywhere between 90µF and 110µF.
The tolerance value is the extent to which the actual capacitance is allowed to vary from its nominal value and can range anywhere from -20% to +80%. Thus a 100µF capacitor with a ±20% tolerance could legitimately vary from 80μF to 120μF and still remain within tolerance.
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. How to Calculate Capacitor Tolerance?
In addition to the above examples, capacitors may also display other specs such as working temperature range, date of manufacture, and even the manufacturer’s name. Capacitors may also indicate their tolerance with a letter placed after the first three numbers. These letters range from A (±0.05pF) to Z (-20 to 80%).
Capacitors use tolerance codes, much like resistors, standardized by the Electronic Industry Alliance (EIA). These codes indicate how much the actual capacitance may deviate from the marked value. This precision is ideal for designing and maintaining high-accuracy circuits.
A capacitor’s tolerance can impact the accuracy of the cutoff frequency, potentially leading to unintended filtering effects. Engineers designing filter circuits must carefully consider capacitance tolerance to achieve the desired performance.

Get PriceFor example, just because two capacitors have the same capacitance value, doesn''t mean they have the same voltage ratings. This information is vital to know because if the wrong capacitor is used (such as a capacitor with a smaller rated voltage rating being used in place of a capacitor with a higher voltage rating) than the capacitor can be damaged and even destroyed. The …
Get PriceA capacitor marking is a code, which indicates the value of the component. It usually consists of three numbers, which indicates the value, and a letter, which indicates the tolerance.

Get PriceThe tolerance rating of a capacitor is expressed with a plus-or-minus value. These represent picofarad''s (±pF) that indicate capacitors with low values (typically less than 100pF) or as a percentage (±%) for capacitors with a higher value (typically higher than 100pF).
Get PriceCapacitor tolerance is calculated based on the marked capacitance value and the tolerance percentage. For instance, if a capacitor is marked as 100 μF with a tolerance of ±10%, it means the actual capacitance can be between 90 μF (100 - 10%) and 110 μF (100 + 10%). This range must be considered during design to ensure circuit performance is ...
