How do you read a ceramic capacitor marking?
The value is expressed in terms of pico-Farads. To decode the value, take the first two digits, then follow them with the number of zeros indicated by the third digit. 104 becomes “10” followed by “0000,” or 100000 pF, more succinctly written as 100 nF.
How do you read a disk capacitor?
The first two numbers represent the value in picofarads, while the third number is the number of zeroes to be added to the first two. For example, a 4.7 μF capacitor with a voltage rating of 25 volts would bear the marking E476. This translates to 47000000 pF = 47000 nF = 47 μF.
How do you find the value of an SMD ceramic capacitor?
Standard-tolerance SMD capacitors use a 3-digit code to mark the capacitance value on the part. The first two numbers will indicate the significant digits, and the third will be the multiplier. ‘R’ is used to indicate the position of a decimal point.
What does 223 mean on a capacitor?
Capacitor Letter Codes Table
| Picofarad (pF) | Nanofarad (nF) | Code |
|---|---|---|
| 15000 | 15 | 153 |
| 22000 | 22 | 223 |
| 33000 | 33 | 333 |
| 47000 | 47 | 473 |
What is the pF value of a ceramic disc capacitor?
So the value is 10 with 3 extra zeros, or 10,000.Ceramic disc capacitor codes are always measured in pico Farads or pF. So it is a 10,000pF capacitor.
What is the value of a 335k capacitor?
EXAMPLES: If a capacitor is marked 103J, its value is 10,000 pF ±5 %. If a capacitor is marked 335K, its value is 3300000 pF ±10 % Standard Capacitor Values
What are the different types of ceramic disc capacitors?
Ceramic disc capacitors come in many versions. For basic general applications, the brown ones are usually utilised for decoupling in low voltage circuits. For switched-mode power supply applications, epoxy coated flame retardant capacitors are usually used.
What is the value of 10 0000 PF on a capacitor?
Here is another example, code 104 is 10 followed by four zeros, hence 10 0000 pF. As you can see, it is so easy that you can do this in your head. EXAMPLES: If a capacitor is marked 103J, its value is 10,000 pF ±5 %. If a capacitor is marked 335K, its value is 3300000 pF ±10 %
