Smd Tantalum Capacitor Voltage Code

They have an equivalent series resistance esr ten times smaller than the esr of aluminum electrolytic capacitors which allows for larger currents to pass through the capacitor with less heat generated.

Smd tantalum capacitor voltage code. Case code 0603 eia english and 1608 iec metric is 063 x 031 in english and 1 6 x 8 mm in metric. Tantalum capacitors solid smd. This coding system is similar to that of the standard system followed by eia and also requires very small amount of space. The voltage rating for tantalum capacitors varies from 2v to more than 500v.

Smd tantalum capacitor markings. The first two form the significant figures and the third is the multiplier. 1411 3528 metric product range. This is particularly important because it is necessary to be able to check the polarity and to have a marking to identify the polarity of the capacitor.

Capacitor working voltage codes. A tantalum electrolytic capacitor is an electrolytic capacitor a passive component of electronic circuits it consists of a pellet of porous tantalum metal as an anode covered by an insulating oxide layer that forms the dielectric surrounded by liquid or solid electrolyte as a cathode because of its very thin and relatively high permittivity dielectric layer the tantalum capacitor. Tantalum capacitors solid smd are available at mouser electronics. The markings on smd tantalum capacitors normally consist of three numbers.

Capacitance tolerance 10. Case size codes are based on the sizes in 0 01s of an inch in english and 0 1 mm in metric. In particular 226 stands for 22 10 6 picofarads i e. That link goes to a page that explains all the details of kemet tantalum capacitor markings.

The tantalum codes can include hight as well. Looks like a recipe for disaster if you ask me. Although smd tantalum capacitors of different series and case sizes may feature different date formats. Some of the capacitors such as the tantalum capacitor and smd electrolytic capacitor use a code consisting of one single character.

Rated voltage is in volts and manufacturing date is in year week format. Why there s a 20v tantalum in a place it could be exposed to 24v is a question you ll have to ask whoever designed the board. Case codes are most often seen with tantalum capacitors. Working voltage code of capacitors.

Therefore the smd tantalum capacitor shown below has a value of 47 x 10 5 pf which works out to be 4 7µf. Looks like it is 20v 47microfarad tantalum capacitor. Smd tantalum capacitor markings in some cases the only marking shown on the capacitor may be a bar across one end indicating the polarity. Values are in picofarads.
