Thus, abbreviated markings are used in such cases wherein three characters are used to mark the code of the capacitor. May 9, 2019 in this section you know ceramic capacitor code value, how to read capacitor value of ceramic capacitor. A separate code, the 25pair color code, is used to identify wires in some telecommunications cables. Its the same as the color code except the code is given only in numbers. For 3 digits capacitor code, the first two digits are the capacitance value in pf.
If the capacitor code consist only 1 or 2 digits, it is simply their capacitance value in picofarads pf. Understanding capacitor codes and markings homemade. Capacitor color code the electronic color code systems are various types in which, well known resistor color code system is used for identifying the value of resistors. Its a reproduction of a radio manufacturers association poster from the 1940s or 1950s. The 1st and 2nd numbers are significant digits and 3rd one is a multiplier. Change the size of the plates and the distance between them. For example if a ceramic capacitor has a code 5 and other has 47, their respective capacitance values are 5 pf and 47 pf.
For example a resistor marked 503 is not a 5 hundred and 3 ohm resistor but the digits 5 0 followed by 3 zeros or 50,000 ohms. Using this color scheme we can easily identify the capacitance values, voltages and tolerance values of any capacitor.
