What is the capacitor number code?
Generally the code consists of 2 or 3 numbers and an optional tolerance letter code to identify the tolerance. Where a two number code is used the value of the capacitor only is given in picofarads, for example, 47 = 47 pF and 100 = 100pF etc.
How do you find the capacitor code?
For 3 digit’s capacitor code, the first two digits are the capacitance value in pF and the third digit is a multiplier factor of first two digits to calculate the final capacitance value of the capacitor. The 3rd digit ranges between 0-6. It can’t exceed more than 6. If 3rd digit is 0, it means multiplier factor of 1.
What do the letters and numbers on a capacitor mean?
Two numbers, one of them followed by a letter: The number followed by a letter indicates the capacitance and tolerance of the cap, as in the. previous case. The other number is the rated voltage (in volts).
What does 103 written on a capacitor mean?
This code indicates what the capacitance of the capacitor is. 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.
How do you read a capacitor color coded?
Fig. 3 – An Example to Understand How to Read Capacitor Color Markings
- The first colour band is Brown. That means the first digit is 1.
- The second colour band is Red. That means the second digit is 2.
- The third colour band is Green.
- The fourth colour band is white.
- The last colour band is Yellow.
What do the colors on a capacitor mean?
The colors painted on the capacitors body are called color bands. All the color bands painted on the capacitors body are used to indicate the capacitance value and capacitance tolerance. Each color painted on the capacitors body represents a different number.
What color wires go on a capacitor?
| HVAC Capacitor Wiring Color Codes & Connections – Basics | |
|---|---|
| Wire Color | Typical Connections Blower Assembly / Fan |
| Red | |
| Yellow | From a fan motor controls the medium speed motor |
| White | Common wires connect to the grounded (neutral) side of power source |
What is the voltage rating of a ceramic capacitor?
Ceramic capacitors range in size from a few picofarads to one or two microfarads, but their voltage ratings are often modest. A three-digit code is usually inscribed on the body of ceramic capacitors to identify their capacitance value in pico-farads.
What is a 3 digit code on a capacitor?
A three-digit code is usually inscribed on the body of ceramic capacitors to identify their capacitance value in pico-farads. The first two digits usually represent the capacitor’s value, while the third digit represents the number of zeros to be added.
What does 103 mean on a ceramic disc capacitor?
A ceramic disc capacitor marked 103, for example, would indicate 10 and 3 zeros in pico-farads, which is equal to 10,000 pF or 10nF. The numerals 104, for example, represent 10 and 4 zeros in pico-farads, which is comparable to 100,000 pF or 100nF, and so on.
How do you read a capacitor with a j value?
For example, a capacitor labeled 474J should be read as 47 times the value listed in Table 1 corresponding to the third number, in this case, 10000: 47 * 10000 = 470000 pF = 470 nF = 0.47µF, with the J indicating a 5% tolerance. If a temperature coefficient is present, the second letter will be it.
