Reading Ceramic Capacitor Values

10 base value.

Reading ceramic capacitor values. Values are normally printed on capacitors in micro farad uf with voltage. You can either memerize the formula or use a calculator to figure them out. The ceramic caps the smaller values in the kit are 50v rated ceramic capacitors. When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.

100000 pf 100nf. The resulting number is the capacitance in pf. 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. 4 number of zeros to add.

0r5 is 0 5 1r0 is 1 0 and 2r2 is 2 2 etc. 10 pf 22 pf 100 pf 1 nf 10 nf 100 nf. The multimeters which can read capacitance are usually costlier better. Ceramic disc capacitor code label will normally consist of three numbers followed by a letter.

10 6 10 to the power 6 pico farad pf is equal to 1 micro farad uf. For example 101 represents 100 pf. They are very easy to decode to find the value. This is why manufacturers started using a three digit code to mark ceramic capacitors.

The digits 10 followed by one additional zero. Read the tolerance code on ceramic capacitors. The first two significant digits represent the first two digits of the actual value which is 47. The ceramic capacitor is labeled as 104.

The value of the capacitor is denoted in picofarads for ceramic film and tantalum capacitors but for aluminium electrolytic capacitors the value is denoted in microfarads. Ceramic disc capacitors have two to three digits code printed on them. Here is how to read ceramic capacitor values. The capacitor value calculator will convert the three digit code into a capacitance value.

We can not directly measure capacitance with ordinary multimeters like that we have shown on article on multimeter for dummies. 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 first two digits represent the value of the capacitor and the third one the number of zeros to add to the right. The third digit is the multiplier which is 1000.

From left to right. 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. These are small nonpolarized caps with yellow blob for their body. With this we get the capacitor value in picofarads.
