How To Read Capacitor Code

The first two digits represent the value of the capacitor and the third one the number of zeros to add to the right. How to read capacitor codes.

How to read capacitor code. Capacitance is measured in farads. Large capacitor have the value printed plainly on them such as 10uf ten micro farads but smaller disk types along with plastic film types often have just 2 or three numbers on them. There are a number of subtle differences in the capacitor codes and markings used for different types of leaded capacitors.

Work out the capacitance units from context. The capacitor on the left is of a ceramic disc type capacitor that has the code 473j printed onto its body. There are various different ways in which the marking is done on the capacitors.

The component deciding the coding can be surface mount technology. Instead they have a 3 digit coding system. Read the capacitance of smaller bodied capacitors as two or three numbers.

How to read a capacitor reading compact capacitor codes write down the first two digits of the capacitance. First most will have three numbers but sometimes there are just two numbers. One farad is a huge capacitor so most normal capacitors have values in the micro farad 0000001f 1uf 10 6 or pico farad 0000000000001f 1pf 10 12 range.

Metallized film capacitor code. How to read capacitor code step 1. With this we get the capacitor value in picofarads.

Large capacitors usually have their value printed plainly on them such as 10uf ten micro farads. Look for a letter code. These are read as pico farads.

The type of component acts as a deciding factor of the types of the codes used. Some capacitors are defined. On a larger capacitors there is sufficient space to mark the value the tolerance working voltage and often other data such as the ripple voltage.

Read codes that contain letters instead. Capacitor voltage code and capacitor tolerance codecapacitor identification codes and ceramic capacitor code chart. Polyster film capacitor code.

How to read capacitor codes. The markings format is dependent upon what type of capacitor is given. In this section you know ceramic capacitor code value how to read capacitor value of ceramic capacitor.

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. Read the value directly on larger bodied capacitors. Understand the units of measurement used for capacitors.

Use the third digit as a zero multiplier. Ceramic capacitors are way smaller than electrolytics and thus the full value plus unit cant be written on them. Read the tolerance code on ceramic capacitors.
