Samsung MLCC Part Number Decoding

A typical code can be split into 11 fields, for example:

CL 03 B 104 K Q 8 N N N C

Field	Meaning
1	Series
2	Package size
3	Dielectric type
4	Capacitance value
5	Tolerance
6	Rated voltage
7	Thickness
8	Electrode/termination
9	Product category
10	Internal code
11	Packaging

1. Series

CL = multilayer ceramic capacitor (MLCC).

2. Size code (examples)

`1`	`03=0201(0603), 05=0402(1005), 10=0603(1608), 21=0805(2012), 31=1206(3216)`

3. Dielectric (examples)

`1`	`C=C0G, A=X5R, B=X7R, F=Y5V, X=X6S ...`

4. Capacitance code

3-digit format: first two are significant figures, third is multiplier (in pF).
Example: 104 = 100000 pF = 100 nF.
R indicates decimal point, e.g. 4R7 = 4.7 pF.

5. Tolerance (examples)

`1`	`F=+-1%, G=+-2%, J=+-5%, K=+-10%, M=+-20%, Z=+80/-20%`

6. Rated voltage (examples)

`1`	`R=4V, Q=6.3V, P=10V, O=16V, A=25V, L=35V, B=50V, C=100V, D=200V ...`

7. Thickness (examples)

`1`	`3=0.30mm, 5=0.50mm, 8=0.80mm, A=0.65mm, D=1.00mm, H=1.60mm ...`

8. Termination type

Code indicates plating/electrode material combinations for reflow/process compatibility.

9. Product class

Code denotes product line/category (general use, automotive, RF, etc.).

10. Internal manufacturing / control code

Vendor-internal field.

11. Packaging code (examples)

`1`	`B=bulk, C=paper tape 7", D=paper tape 13", O=paper tape 10", F=embossed tape 13" ...`
