Ceramic Capacitor Value Identification
When the first two numbers are multiplied with the multiplier the resulting value is the value of the capacitor in picofarads.
Ceramic capacitor value identification. 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. Characteristics precision and tolerances. Then the 4 1 st digit the 7 2 nd digit the 3 is the multiplier in pico farads pf and the letter j is the tolerance and this translates to. Ceramic capacitor definition a ceramic capacitor is a capacitor which uses a ceramic material as the dielectric.
Ceramic disc capacitors have two to three digits code printed on them. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. Then by just using numbers and letters as codes. Class 1 and class 2.
The two most common types are multi layer ceramic capacitors and ceramic disc capacitors. The first two numbers describe the value of the capacitor and the third number is the number of zeros in the multiplier. There are two classes of ceramic capacitors available today. Let s face it a farad is a lot of capacitance.
Capacitor values are usually tiny often in the millionths or billionths of a farad. The following prefixes are the modern convention. To express those small values succinctly we use the metric system. 47pf 1 000 3 zero s 47 000 pf 47nf or 0 047uf the j indicates a tolerance of 5.
