Capacitor Tolerance Codes

May 29, 2018

Capacitor ratings arent all that precise but you can at least work out how imprecise the ratings are by deciphering the following letter tolerance codes. Once again dont expect to find all possible combinations of values dielectrics and tolerances.

The tighter tolerances mostly apply to small c0g capacitors and the looser tolerances to larger class 2 4 ceramics.

Capacitor tolerance codes. Table 5 shows the eia tolerance codes for ceramic capacitors. Physically small capacitors are especially difficult to read due to the limited space available for printing. How to read a capacitor.

Unlike resistors capacitors use a wide variety of codes to describe their characteristics. 47pf 1000 3 zeros 47000 pf. Both parts of each calculator work separately you do not have to enter both value code and tolerance code.

Metallized film capacitor code. Capacitor code calculator these calculators can convert the 3 digit value codes and alphabetical tolerance codes found on some capacitors into the corresponding value and vice versa. The code used is actually the same as that used with resistors as it utilises the eia scheme.

With smaller disc type capacitors tolerance is most often indicated by a single letter code which is sometimes placed by itself on the body of the capacitor or after the three digit mark such as. Code tolerance b 01 pf c 025 pf d 05 pf f 1 g 2 j 5 k 10 m 20 z. Some capacitors have a tolerance code.

The tolerance may be next to the value. The capacitor tolerance chart below shows some common tolerance letter codes. This type of capacitor marking is used less these days but may be seen on some older capacitors.

In this section you know ceramic capacitor code value how to read capacitor value of ceramic capacitor. Displayed capacitor chart with tantalum capacitor color codes capacitor code guide mica capacitor values etc. Like resistors the tolerance of the capacitor indicates how close the printed value meets reality.

Component manufacturers indicate tolerance with a letter code that refers to variances as small as 05pf indicated as a up to 2080 written as z. Polyster film capacitor code. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body.

Capacitor voltage code and capacitor tolerance codecapacitor identification codes and ceramic capacitor code chart. Some older capacitors use a form of colour code. Learn deeply about capacitor chart.

Then the 4 1 st digit the 7 2 nd digit the 3 is the multiplier in pico farads pf and the letter j is the tolerance and this translates to.
