How do you read a ceramic capacitor code?

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.

What is the symbol for a ceramic capacitor?

Ceramic disc capacitor code normally consists of a three-digit number followed by a letter. It is very easy to decode to find the capacitor value. The first two significant digits signify the first two digits of the actual capacitance value, which is 47 (the above capacitor).

How do you read a SMD ceramic capacitor?

Ceramic capacitor usually uses 3 digits like 102, 103, 101 for indicating its value and values in term of Pico farad. In ceramic capacitor if the three digits are ABC, then the value would be AB*10^C Pico farad. Here the digit is 104 that means 10*104pf = 100000pf = 100nf = 0.1uf.

Which is a 4.7uf 25V low impedance electrolytic capacitor?

High frequency Low impedance 4.7uf 25v SMD electrolytic capacitor is available for high density surface mounting and reflow soldring, and it has high stability and reliability. We have a sound raw material cooperation system and cargo inspection mechanism. Products with high stability, high temperature, small size, small tolerance and so on.

What are the markings on a ceramic capacitor?

Markings of Ceramic Capacitor: The markings on a ceramic capacitor are more concise in nature since it is smaller in size as compared to electrolytic capacitors. Thus, for such concise markings many different types of schemes or solutions are adopted. The value of the capacitor is indicated in “Picofarads”.

Are there any markings on SMD tantalum capacitors?

These capacitors are loaded in a machine called pick and place which eliminates any marking need. Markings of SMD tantalum capacitor: Similar to the ceramic capacitors, there is absence of markings which are observed in some of the tantalum capacitors. The tantalum capacitors only consist of the polarity markings.

What is the UF code for a capacitor?

Some capacitors are only marked as 0.1 or 0.01, mostly in these cases the values are given in uF. Some small capacitance capacitors can be marked with an R between numbers. If code is 3R9 then R is an indicator of values Less than 10pF and has nothing to do with resistance. 3R9 would be 3.9pF.
