What does 103k on a capacitor mean?

What does 103k on a capacitor mean?

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. So the value is 10 with 3 extra zeros, or 10,000.

What does K mean in capacitance?

k = relative permittivity of the dielectric material between the plates. k=1 for free space, k>1 for all media, approximately =1 for air. The Farad, F, is the SI unit for capacitance, and from the definition of capacitance is seen to be equal to a Coulomb/Volt.

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. Related questions (More answers below)

What is my capacitor value?

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 check the value of a capacitor?

To test the capacitor with a multimeter, set the meter to read in the high ohms range, somewhere above 10k and 1m ohms. Touch the meter leads to the corresponding leads on the capacitor, red to positive and black to negative. The meter should start at zero and then moving slowly toward infinity.

Why do electrical engineers use j instead of i?

Electrical engineers use imaginary numbers very frequently, for instance 3 + j7, where . This is different than the way most mathematicians would write it: 3 + 7i. Engineers use j since i is reserved to mean current, and we place the symbol in front of the number rather than behind it.

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 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 %

What is the tolerance of a ceramic disc capacitor?

My article on Ceramic Disc Capacitor Values might help with the tolerance letters. 103K is a 10 nF capacitor with a 10% tolerance. 222K is a 2.2 nF capacitor with a 10% tolerance. 823K is 82 nF 10% tolerance.

What is the value of Oluf 10% of a capacitor?

This decodes as OluF 10%. The first two figures give 10 the third figure’4′ gives 0000 and the last ‘k’ = 10%. Therefore, the capacitor is 10,0000pF, 10%. This is normally expressed as 0.0luF or l00nF – capacitors with a value below 0.001uF are expressed in Picofarads.
