What do the numbers on my capacitor mean?
What do the numbers on my capacitor mean?
Many capacitor manufacturers use a shorthand notation to indicate capacitance on small caps. The resulting number is the capacitance in pF. For example, 101 represents 100 pF: the digits 10 followed by one additional zero. If there are only two digits listed, the number is simply the capacitance in pF.
What is a 471 capacitor?
Ceramic capacitors of special shapes and styles are used as capacitors for RFI/EMI suppression, as feed-through capacitors and in larger dimensions as power capacitors for transmitters. …
What is 1k capacitor?
k means thousand. On a capacitor, when it’s used, the implied unit is the picofarad. So 470k on a capacitor means 470,000 picofarads, or 0.47 microfarads.
What is a 103 ceramic capacitor?
The example capacitor has a 3 digit number printed on it (103). The third digit indicates the number of extra zeros, in this case 3 extra zeros. 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.
How are capacitors letter coded?
The Capacitor Colour Code system was used for many years on unpolarised polyester and mica moulded capacitors. A three letter code consists of the two value digits and a multiplier much like the resistor colour codes in the resistors section. For example, the digits 471 = 47*10 = 470pF.
What does the 3 digit capacitor code 220 stand for?
The 3 digit capacitor code 220 stands for 22 pF, in words: twenty-two picofarads capacitance. This is a simple online calculator for color band resistor marking, inductor color band marking, ceramic or tantalum capacitor 3 digit marking and SMD resistor 3-digit, 4-digit, 10%, 5%, 2% and EIA-96 (E96) 1% tolerance code marking.
What is the tolerance capacitor marking code for an EIA capacitor?
EIA Tolerance Capacitor Marking Code Letter code Tolerance Z +80%, -20% – this is used with electroly M ±20% K ±10%
What do the letters on a capacitor mean?
Look for a letter code. Some capacitors are defined by a three number code followed by a letter. This letter represents the tolerance of the capacitor, meaning how close the actual value of the capacitor can be expected to be to the indicated value of the capacitor. The tolerances are indicated as follows.
How to decode the value of a ceramic disc capacitor?
Ceramic disc capacitor code / label will normally consist of three numbers followed by a letter. They are very easy to decode to find the value. The first two significant digits represent the first two digits of the actual value, which is 47. The third digit is the multiplier, which is ×1000. The letter J signifies the tolerance of ±5 %.
