The important one to be noted is that usually capacitor values range is Pico farads (10 -12 F). M ost of them have 3 numbers. The 3 numbers are having unique significance. The 1 st and 2nd numbers are significant digits and 3rd one is a multiplier. Mostly the last digit signifies how many zeroes to be added after the first two digits.
2 digits and nothing else = pF. xNy = x.y nF. The small ceramic capacitors with 2 digits markings can be identified with their color and the type of markings: Generalizing, The small brown capacitors have written with the value of the capacitance with a multiplier 10^ (-12) i.e. picofarad The capacitor with value written as 1n0, 2n2, 47n means :
A: The most common type of capacitor code value is the three-digit code, which represents the capacitance in picofarads (pF). For example, a capacitor with the code “104” indicates a capacitance of 10,000 pF or 10 nF. Q: How do I interpret a three-digit capacitor code value?
If the first three characters are all numbers, continue to the next step. Use the third digit as a zero multiplier. The three-digit capacitance code works as follows: If the third digit is 0 through 6, add that many zeroes to the end of the number. (For example, 453 → 45 x 10 3 → 45,000.) Work out the capacitance units from context.
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.
A: Capacitor code values are used to represent the capacitance value of a capacitor component. Capacitors are electronic components that store and release electrical energy. The code values help in identifying the capacitance value of a capacitor without having to write the full value in Farads. Q: How are capacitor code values expressed?

Typically, ceramic capacitors use a three-digit code: First two digits: These represent the significant figures of the capacitance value in picofarads (pF). Third digit: This is a multiplier, indicating the number of zeros to add to the first two digits. Example: 104: First two digits: 10; Third digit: 4; Calculation: 10 * 10^4 = 100,000 pF = 0 ...

For capacitors facing between 1pF to 1μF (almost all capacitors except for electrolytic), reference values are indicated with a three-digit number followed by a letter. The first two digits indicate the starting number, while the third digit represents the number of zeros that must be added to the starting number to get the ending value.
Common capacitors are often made of two small pieces of metal foil separated by two small pieces of insulation (Figure (PageIndex{1b})). The metal foil and insulation are encased in a protective coating, and two metal leads are used for connecting the foils to an external circuit. Some common insulating materials are mica, ceramic, paper, and Teflon™ …
Ceramic disc capacitors with 3-digit codes. But some have the capacity printed directly on the case. For instance, you might see 1000µF 6.3V. This labeling implies it has a 1000µF charge capacity and can operate safely at voltages not exceeding 6.3V. However, if you encounter the alphanumeric code, here''s what the characters mean. 1st and 2nd numbers give the …
Larger capacitors display their capacitance, operating voltage, and tolerance directly. Small capacitors, due to size constraints, use shorthand codes or color codes. If the capacitor has two digits printed on it, the number is capacitance in picofarad and if it has three digits, the third digit represents a number of zeros added to the first ...
To determine the capacitance, combine the first two digits and multiply them by 10 raised to the power of the third digit. For example, a code of "104" translates to 10 x 10^4 pF = 10,000 pF or 10 nF.
For larger capacitors, two main parameters are displayed: capacitance and breakdown voltage. Capacitance is usually indicated in microfarads (μF). For instance, "150μF" clearly denotes 150 microfarads. 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.
Write down the first two digits of the capacitance. Older capacitors are less predictable, but almost all modern examples use the EIA standard code when the capacitor is …
Write down the first two digits of the capacitance. Older capacitors are less predictable, but almost all modern examples use the EIA standard code when the capacitor is too small to write out the capacitance in full.
The two-digit code, though seemingly cryptic, is a concise way of representing the capacitance value. By understanding the digit-multiplier relationship and the common letter multipliers, you can confidently decode these markings and select the right ceramic capacitor for your circuit needs.

In the capacitor in Figure 2, …
If a capacitor is marked "104," the first two digits "10" represent the capacitance value''s first two significant digits. The third digit "4" indicates the multiplier. Therefore, the capacitance value10 * 10^4 pF, or 100,000 pF (100 nF).
The capacity of Capacitor increases with decrease in the gap between the conductors and increase of the area of conductors.
