Common MLCC package sizes

MLCC, that is, Multilayer Ceramic Capacitors, also known as chip capacitors or chip capacitors. According to the American Electrotechnical Association (EIA) standards, the MLCC of different dielectric materials can be divided into three categories according to temperature stability: the ultra-stable dielectric materials are COG or NPO; The stable medium material is X7R; The usable dielectric material is Y5V.

According to the British standard, its pin package usually comes in the following 12 models: 0201, 0402, 0603, 0805, 1206, 1210, 1812, 1825, 2225, 3012, 3035.

Among them, 0201/0402/0603/0805/1206 is a common package size of the chip capacitor, the capacity range is generally 0.5pF~1uF. 1210/1812/1825/2225/3012/3035 is a large-size patch capacitor with a capacity range of 1uF~100uF.

The specific package size parameters in British and metric are shown below:



Major original MLCC naming rules



Take YAGEO (YAGEO) as an example:

"CC" indicates the name of the series, that is, the general multi-layer ceramic chip capacitor, such as CC0603KRX7R9BB103; (Others, such as AC for automotive capacitors, CQ for HI-Q high-frequency capacitors, and CX for X2Y® capacitive filters).

"0603" represents the package size, which is the four digits after the "series name" (CC/AC/CQ/CX, etc.), and the standard EIA package commonly used sizes are 0201, 0402, 0603, 0805, 1206, 1210, 1808, 1812, 2010, 2512, etc.

"K" is the error level: the first letter after the size indicates the error level

A=±0.05PF B=±0.1PF C=±0.25PF D=±0.5PF F=±1PF

G=±2PF J=±5% K=±10% M=±20% Z=-20%~+80%

"R" stands for package form: 1 letter after error

R stands for 7-inch paper roll, P stands for 8-inch paper roll, and K stands for 7-inch plastic roll.

"X7R" dielectric material (temperature characteristics) : 3 letters after package form

Material represents capacitance temperature characteristics, common dielectric materials are NPO, X5R, X7R, Y5V.

"A" is the rated voltage: a digit or letter after the dielectric material

4=4V, 5=6.3V, 6=10V, 7=16V, 8=25V,0=100V, A=200V, B=500V, C=1KV, D=2KV, E=3KV, etc.

Solder pin material: 1 letter after voltage

A = PdAg, B = Ni-barrier, C =Ni/Au.

Electrode: 1 letter after the welding foot material

B = Base metal electrode (X5R/X7R), N = non-base metal electrode (NPO).

"102" is the nominal capacity value: the last three digits or numeric letters

Significant digit + zero number, third digit is exponent. If the tolerance value has a decimal point, use R to represent the decimal point. For example, 5R6=5.6PF,100=10PF,101=100PF, 102=1000PF, 103=10,000PF......





Murata coding rules







Example:



GRM stands for tinned electrode (common chip ceramic capacitor)

The commonly used Murata capacitors are GRM ordinary chip ceramic capacitors and GNM ordinary chip capacitors.

18 Indicates size (L * W) (1.6*0.8mm)

The common size in China is (length * width)1.6*0.8mm (unit: mm). The international universal size is expressed in inches 0603(unit is inch),

Murata commonly used code 03,15,18,21,31,32,42,43,55 etc, specific corresponding value is as follows:

03-0.6 * 0.3 mm - 0201

15-1.0 * 0.5 mm - 0402

18-1.6 * 0.8 mm - 0603

21-2.0 * 1.25 mm - 0805

31-3.2 * 1.6 mm - 1206

32-3.2 * 1.5 mm - 1210

42-4.5 * 2.0 mm - 1808

43-4.5 * 3.2 mm - 1812

55-5.7 * 5.0 mm - 2220

8 indicates thickness (T) (0.8mm)

Commonly used thickness Murata codes are 5,6,8,9,B,C,E, etc. The specific corresponding values are as follows:

5-0.5 mm

6-0.6 mm

8-0.8 mm

9 -- 0.9 mm

B - 1.25 mm

C - 1.6 mm

E - 2.5 mm

R7 for material (X7R)

Commonly used material Murata code is 5C, R6, R7, F5, etc., the specific corresponding values are as follows:

5C----COG/NPO/CH R6----X5R R7----X7R F5-----Y5V

5C operating temperature is -55 degrees -- +125 degrees, temperature coefficient is 0+-30ppm/ degree;

R6 operating temperature is -55 degrees -- +85 degrees, temperature coefficient is +-15%;

R7 operating temperature is -55 degrees -- +125 degrees, temperature coefficient is +-15%;

F5 operating temperature is -30 degrees - +85 degrees. The temperature coefficient is +22,-82%

5C material is generally used for small volume values below 100pf, R7 material is generally used for 100PF -- 1uf, R6 material is generally used for more than 1uf, and F5 material is generally used for those with low precision requirements. The selection of material directly affects the accuracy of capacitance value and temperature resistance.

1C indicates rated voltage (DC16V)

Common voltage Murata indicates 0J, 1A, 1C, 1E, 1H, etc., corresponding values are as follows:

0 j -- -- -- -- -- - 6.3 V 1 a -- -- -- -- -- - 10 V 1 c -- -- -- -- -- - 16 V 1 e -- -- -- -- -- - 25 V 1 h -- -- -- -- -- - 50 V

225 indicates electrostatic capacity (22UF)

It is represented by three alphanumeric digits, and the unit is picofart (pF). The first and second digits are significant digits, and the third digit represents the number of zeros after the significant digit, which is represented by the capital letter "R" when there is a decimal point, and all digits are significant digits.

K represents the allowable deviation of electrostatic capacity, that is, the commonly said gear and accuracy (+-10%).

Commonly used gears are B, C, D, J, K, M, Z, the specific corresponding values are as follows:

B = + 0.1 pF C = = + 0.5 + 0.25 pF D pF J = K = + + - 5% - 10% M = Z = + 80 + - 20%, to 20%

The accuracy of normal 5C material can be B, C, D and J files; The accuracy of R6 and R7 materials can be K and M files; F5 material accuracy is Z-stop.

E15 Individual specification codes

D Packing method (diameter 180mm paper tape braid tray)

Commonly used packaging methods are L, D, B, etc., the specific ways are as follows:

L means embossed tape (plastic) braid disc with a diameter of 180mm; D indicates paper tape braid disc with a diameter of 180mm; B stands for loose bag.
