Ceramic Disc Capacitor Values / Code / Label
Ceramic capacitors, which are usually tiny "pancakes" with two pins, typically list the tolerance value as one letter immediately after the three-digit capacitance value. This letter represents the tolerance of the capacitor, meaning how close the actual value of the capacitor can be expected to be to the indicated value of the capacitor.
The small ceramic capacitors with 2 digits markings can be identified with their color and the type of markings: Generalizing, The …
Reading capacitor markings involves identifying several key attributes. The capacitance value often marked directly in microfarads (μF), nanofarads (nF), or picofarads (pF). The …
Voltage Rating. For the radial tantalum capacitors after the capacitance code, another two-digit code shows the maximum voltage rating of the capacitor.The unit of working voltage is always in volts(V). In the case of SMD tantalum capacitors, working voltage is marked in alphabetical codes; i.e. E, G, J, A… etc.. We have provided the table …
18 · Some capacitors will have their capacitance and voltage ratings printed directly on the component, but some may have a three or four digit code. Here''s a clear explanation …

Understanding Ceramic Disc Capacitor Values
Alternatively, a three-digit code might be used, like "224," which translates to 220,000 picofarads (pF). This is calculated from 22 x 10^4. In these codes: The last digit shows the power of ten (e.g., 1-6). Numbers 8 and 9 convert to multipliers of 0.01 and 0.1 respectively. ... 2. How to Read Capacitor Markings?
In such capacitors, the upper two color bands denote the first and second digit. The Third color band gives the tolerance value and the last band gives the working level of voltage. The chart for the same is placed below : – Fig. 2 – Capacitor Color Codes. Let''s take an example to understand it in a better way.
How to Test a Capacitor with a Digital Multimeter: The ...
Reading Ceramic Capacitor Values reading ceramic capacitor values. Reading ceramic capacitor values is all about understanding a simple code system. Here''s a breakdown: The Code: Most ceramic capacitors have a three-digit code printed on their surface. This code represents the capacitance value of the capacitor in picofarads (pF).
How to Measure Capacitance with a Digital Multimeter
Reading Two Digit Capacitor Codes. Two-digit code capacitors are less common than three-digit ones, but they do exist. Typically, two-digit codes are used for capacitors with values less than 10 picofarads (pF). Here''s how you read a two-digit code: The first digit is the significant figure.
This value is in unit volts (V). In the capacitor example above, the capacitor has a MWV of 35V. This means that in a circuit, a designer should make sure that no more than 35V is dropped across the capacitor. If the capacitors receives more than 35V, then it can be either partially or totally destroyed and, thus, rendered useless in a circuit.
