The capacitor color code chart is given below to identify the value of the capacitor. The first color is considered as the 1 st digit in color chart, the second color band is 2 nd digit, the third band is a multiplier, the 4 th band is tolerance and the fifth color band is voltage rating of the capacitor. In case of Color coded capacitors, capacitor body consists of color bands and by using a capacitor color code chart we can easily identify the capacitor value. Mostly unpolarized polyester capacitor or mica molded capacitors are color coded. Capacitor Color CodingĪs like resistor value finding by color coding, capacitors are also color coded for identifying their values. If the values are represented with slashes, then the first digit represents value in UF, the second digit gives tolerance and the third represents maximum voltage rating.Į.g. If an alphabet is given between the digits, it represents a decimal and the value is in KPFĨ. If the number is a floating point decimal number, then the capacitance value is in uF.ħ.
For a 4-digit number, if the 4 th number is a zero, then the capacitance value is in pF.Ħ. For a capacitance value of 104 or 100000 in pF, it is 100KpF or n or 0.1uF.ĥ. If the value is obtained in PF, then it is easy to convert it into KPF or uFįor example, PF / 1000 = KPF or, PF / 10, 00000 = uF. For a 3-digit value, the third digit represents the number of zeros after the second digitĤ. If the third number is zero, then the value is in Picofaradģ. The number printed on the capacitor’s body represents the capacitance value in Pico Farads.Ģ. The capacitor is destroyed if a fixed resistance value is detected.Some more methods of finding the capacitor values include the followingġ. The capacitance pointer of roughly 0.1F beats (charges) when measured with the 10k block of the pointer meter, and it returns to infinity after being motionless. Remove the capacitor from the circuit and check its resistance value, which should be infinite. The multimeter measures the resistance between the two pins of the capacitor if it is detected online, which is really the "total resistance value" of the external circuit linked to the capacitor. When measuring the capacitance, at least one end of the chip capacitor must be disconnected to exclude the influence of the external circuit before testing.Ģ）Use a multimeter to double-check. Most capacitors actually have the numeric values stamped on them, however, some are color coded as resistors are. This calculator is designed to give the value of color coded poly capacitors. At present, some digital multimeters also add this function. This calculator requires the use of Javascript enabled and capable browsers. The capacity of the capacitor can be measured with a special capacitance tester. 4.Damage phenomenon and detection method of chip capacitors?ġ) The same type of capacitor, the larger the size or the darker the color, the larger the capacity.
