How do you read a capacitor code?

How do you read a capacitor code?

If you have a capacitor that has nothing other than a three-digit number printed on it, the third digit represents the number of zeros to add to the end of the first two digits. The resulting number is the capacitance in pF. For example, 101 represents 100 pF: the digits 10 followed by one additional zero.

What does J mean on a capacitor?

The letter on a capacitor designates the tolerance. J = +/- 5%

How do you read a capacitor color coded?

Fig. 3 – An Example to Understand How to Read Capacitor Color Markings

  1. The first colour band is Brown. That means the first digit is 1.
  2. The second colour band is Red. That means the second digit is 2.
  3. The third colour band is Green.
  4. The fourth colour band is white.
  5. The last colour band is Yellow.

How do you read a ceramic capacitor code?

The value is expressed in terms of pico-Farads. To decode the value, take the first two digits, then follow them with the number of zeros indicated by the third digit. 104 becomes “10” followed by “0000,” or 100000 pF, more succinctly written as 100 nF.

What is color code of capacitor?

Capacitor Voltage Colour Code Table

Band Colour Voltage Rating (V)
Yellow 20 500
Green 25 600
Blue 35 700
Violet 50 800

What is the most common type of non-polarized capacitor?

Ceramic capacitors
Ceramic capacitors are the most common type of non-polarized capacitor.

What is the numerical code for 0.01 MF capacitors?

Capacitor Letter Codes Table

Picofarad (pF) Nanofarad (nF) Code
10 0.01 100
15 0.015 150
22 0.022 220
33 0.033 330

Can I use a 440v capacitor instead of a 370v?

The Voltage Rating is What it Can Handle, Not What it Will Produce. Many techs think they must replace a 370v capacitor with a 370v capacitor. The voltage rating displays the “not to exceed” rating, which means you can replace a 370v with a 440v but you cannot replace a 440v with a 370v.

What is the alphanumeric code for capacitors?

This table is designed to provide the value of alphanumeric coded ceramic, mylar and mica capacitors in general. They come in many sizes, shapes, values and ratings; many different manufacturers worldwide produce them and not all play by the same rules.

Do you have to enter tolerance code in capacitor calculator?

These calculators can convert the 3-digit value codes and alphabetical tolerance codes found on some capacitors into the corresponding value and vice-versa. Both parts of each calculator work separately – you do not have to enter both value code and tolerance code. Details of capacitor markings can be found in the technical data section.

What does N51 mean on a surface mount capacitor?

Similarly n51 indicates a 0.51nF, or 510 pF capacitor, etc . . SMD ceramic capacitor codes: Surface mount capacitors are often very small and do not have the space for markings. During manufacture the capacitors are loaded into a pick and place machine and there is no need for any markings.

How to read the capacitor code for resistance?

Some small capacitance capacitors can be marked with an R between numbers. If code is 3R9 then R is an indicator of values Less than 10pF and has nothing to do with resistance. 3R9 would be 3.9pF. 105J=10×105 =1000000pf=1000nf=1.0uf j= +/- 5% Tolerance
