## How do you read capacitor value?

Read codes that contain letters instead. If the letter is an R, replace it with a decimal point to get the capacitance in pF. For example, 4R1 means a capacitance of 4.1pF. If the letter is p, n, or u, this tells you the units (pico-, nano-, or microfarad). Replace this letter with a decimal point.

### How do you calculate the value of a capacitor?

As the capacitor charges, the value of Vc increases and is given by Vc = q/C where q is the instantaneous charge on the plates. At this instant (time t) there will be a current I flowing in the circuit. We also know that Vs = Vc + Vr and Vc = q/C.

#### What does 103k mean on a capacitor?

The example capacitor has a 3 digit number printed on it (103). The first two digits, in this case the 10 give us the first part of the value. The third digit indicates the number of extra zeros, in this case 3 extra zeros. So the value is 10 with 3 extra zeros, or 10,000.

What is the values of capacitor?

Standard Capacitor Values & Color Codes

These are the most commonly available capacitor values. Tolerances are highly dependent on dielectric and package type.
pF pF pF
1.2 12 1200
1.3 13 1300
1.5 15 1500

How many uF is 10nF?

## What is the difference between 225j and 225K capacitors?

There is no difference in their nominal capacitance value. However, the 225J capacitor will have a 5% tolerance, and the 225K capacitor will have a 10% tolerance. There is a brief explanation of the tolerance codes here but you can find more detail on this by Googling “capacitor codes”.

### Are the capacitor values shown in the table available?

Currently the capacitor values shown in the table are available. Electronics suppliers tend to stock those values that are the most popular, but larger suppliers such as Farnell and RS tend to stock a wider range.

#### What does K stand for on a 400V capacitor?

I assume its a 400V capacitor cant seem to find a conversion chart or anything similar. K stands for +/10% tolerance. K stands for +/10% tolerance. Click to expand… Thank you very much! You must log in or register to reply here.
