Tantalum capacitor codes. Typically the markings on a capacitor may give the figures like 22 and 6v. A typical tantalum capacitor is a chip capacitor and consists of tantalum powder pressed and sintered into a pellet as the anode of the capacitor with the oxide layer of tantalum pentoxide as a dielectric and a solid manganese dioxide electrolyte as the cathode. You may wish to check out our resistor color code table and calculator.
Monolithic capacitor these non polar capacitors have equal length leads that can be installed in either direction and come in many colors. Therefore the smd tantalum capacitor shown below has a value of 47 x 10 5 pf which works out to be 47uf. Three digit codes are often accompanied by an additional tolerance letter code as given below.
It is a component of an electronic circuit that typically consists of a pellet of tantalum metal as the anode covered by an insulating oxide layer that forms the dielectric surrounded by a conductive material as the cathode. A case capacitors u se a letter code for the voltage and eia capacitance code. This indicates a 22uf capacitor with a maximum voltage of 6v.
Smd tantalum capacitor markings. Leaded tantalum capacitors generally have their values marked in microfarads uf. Tantalum capacitors usually have the capacitance value maximum voltage rating and polarity printed right on the component.
The tantalum codes can include hight as well. They are usually tear drop shaped and are all low voltage. This coding system is similar to that of the standard system followed by eia and also requires very small amount of space.
Case code 0603 eia english and 1608 iec metric is 063 x 031 in english and 16 x 8 mm in metric. The vishay identification marking is included if space permits. The markings on smd tantalum capacitors normally consist of three numbers.
For example the digits 471 4710 470pf. A tantalum capacitor is a type of electrolytic capacitor. Leaded tantalum capacitor markings.
A three letter code consists of the two value digits and a multiplier much like the resistor colour codes in the resistors section. Case codes are most often seen with tantalum capacitors. Materials production and styles anode.
Some of the capacitors such as the tantalum capacitor and smd electrolytic capacitor use a code consisting of one single character. Most capacitors actually have the numeric values stamped on them however some are color coded as resistors are. Smd tantalum capacitor markings.
Tantalum capacitor color code chart. The first two form the significant figures and the third is the multiplier. Case size codes are based on the sizes in 001s of an inch in english and 01 mm in metric.
Values are in picofarads.
