Disc Capacitor Value

The real difference between the two is the tolerance. Fixed leaded disc and multilayer ceramic chip capacitors mlcc a ceramic capacitor is a fixed value capacitor where the ceramic material acts as the dielectric.

So it is a 10000pf capacitor.

Disc capacitor value. For example 101 represents 100 pf. Many capacitors are also marked with value tolerance notation and a breakdown voltage. The first two numbers describe the value of the capacitor and the third number is the number.

Larger capacitors the cylindrical aluminum electrolyte type or the double layer type use units of microfarads uf or uf equal to 10 6 farads. The smallest capacitors made from ceramic film or tantalum use units of picofarads pf equal to 10 12 farads. It is constructed of two or more alternating layers of ceramic and a metal layer acting as the electrodes.

Cheap ceramic disc capacitors have a high tolerance 20 or worse. 470 is the code for 47pf you need a code 471 for a 470pf capacitor. If you have a capacitor that has nothing other than a three digit number printed on it the third digit represents the number of zeros to add to the end of the first two digits.

Tolerance means how close the component is likely to be to its listed value. Method of finding the valuemeaning of codes of capacitor ceramic disc capacitors have two to three digits code printed on them. So this is how a capacitor valuecode calculator calculates the ceramic capacitor value from the capacitor code or vice versa.

15100 1500 pf. Additionally capacitors that are polarizedthey have a and a leadalso carry a polarization marking. Work out the capacitance units from context.

Disc capacitors are usually ceramic and for a 5 mm wide capacitor 500v rating sounds reasonable but do check manufacturers datasheet to be sure. The first two digits in this case the 10 give us the first part of the value. When the first two numbers are multiplied with the multiplier.

The digits 10 followed by one additional zero. Hence the value of the capacitor above is 47000 pf 5. The capacitance value will be calculated as follows.

A ceramic disc capacitor does not have a polarity and connects in any direction on the printed circuit board. Capacitors are routinely marked with at least their capacitance value. So the value is 10 with 3 extra zeros or 10000ceramic disc capacitor codes are always measured in pico farads or pf.

If you are new to capacitor codes then the best way to start is with a chart because that way you can see the arrangement of the code. The resulting number is the capacitance in pf. The third digit indicates the number of extra zeros in this case 3 extra zeros.

Similarly if the capacitor code is 152 the 3 rd digit is 2 so multiplier factor is 100. High tolerance means when you buy a 022uf capacitor you might instead get a 03 or a 015.
