How do you see the stencil capacitor naming rules? (II)

(4) Marking method of imported capacitors: Imported capacitors generally have six components.

The first item: the category is represented by letters:

The second item: the two-digit number indicates its shape, structure, packaging method, lead start and relationship with the axis.

The third item: the temperature characteristics of temperature-compensated capacitors, useful letters, and also useful colors, the meaning of which is shown in the following table:

No. Letter Color Temperature coefficient Allowable deviation Letter Color Temperature coefficient Allowable deviation

1 A gold +100 R yellow -220

2 B ash +30 S green -330

3 C black 0 T blue -470

4 G ±30 U purple -750

5 H brown -30 ±60 V -1000

6 J ±120 W -1500

7 K ±250 X -2200

8 L red -80 ±500 Y -3300

9 M ±1000 Z -4700

10 N ±2500 SL +350~-1000

11 P Orange -150 YN -800~-5800

The fourth item: the withstand voltage is represented by numbers and letters, the letters represent valid values, and the numbers represent powers of 10 of the multiplicand.

The fifth item: the nominal capacity, expressed by three digits, the first two digits are valid values, and the third is a power of ten. When there is a decimal, it is represented by R or P. The unit of the ordinary capacitor is pF, and the unit of the electrolytic capacitor is uF.

Item 6: Allowance deviation. Expressed in one letter, the meaning is the same as that of a domestic capacitor. Also useful for color-coded methods, the meaning is the same as that of domestic capacitors.
