Membaca kondensator milar dan keramik mirip dgn menghitung resistor.Angka dibelakang menunjukkan perkaliannya.


Contoh        :   104 ( 100 nf ) artinya 10 X 10.000 = 100.000 pico farad

103 ( 10 nf )   artinya 10 X 1000    = 10.000   pico farad

102 ( 1 nf  )    artinya 10 X 100      = 1000      pico farad

101 ( 100 pf ) artinya 10 X 10        = 100        pico farad

Dan seterusnya seperti itu.


Kondensator Milar



Lihat contoh kondensator milar diatas kodenya 2A104J,maksudnya bagaimana kode di belakang angka tsb?

Berikut ini penjelasannya :

2A maksudnya adalah simbol tegangan.Lalu berapa nilainya?

Lihat tabel diatas,cara membacanya di balik yaitu A2.

A = 1

2 = 00

Jadi tegangannya 100V.

Kemudian kode huruf J adalah toleransi yaitu 5%.

Jadi kapasitor 2A104J = 100 nf ( nano farad ),toleransi 5% dan tegangan maksimal 100V.


Contoh lagi :

Ada kapasitor milar kodenya : 2H224K

Cara membaca : 2H dibaca H2

H = 5

2 = 00

224 = 220 nf

K = 10%

Jadi 2H224K = 220 nf,Toleransi 10%,Tegangan 500V

How to read Capacitor Codes

Grab an LCR or Capacitance meter, read the value of the capacitor you wish to replace. This is assuming the capacitor you are replacing is not damaged beyond the point of a reasonably accurate reading.

Larger capacitors, like electrolytic, have the value printed on them clearly, such as 10uF, but smaller types often have just 2 or three numbers on them.

2 Numbers: These are read as Pico-Farads. An example: 47 printed on a small disk can be assumed to be 47 Pico-Farads (or 47pF).

3 Numbers: The first two are the 1st and 2nd significant digits and the third is a multiplier code. Most of the time the last digit tells you how many zeros to write after the first two digits, but this is not ALWAYS the case. eg. an extra digit might be indicating an ESR value.

Capacitor Speak – milli, micro, nano, pico,

1 milli Farad (or any other unit) is 1/1,000th  or .001 times the unit. (10-3)

1 micro = 1/1,000,000 or 0.000 001 times the unit (10-6 )

1 nano = 1/1,000,000,000 or 0.000 000 001 times the unit (10-9 )

1 pico = 1/1,000,000,000,000 or 0.000 000 000 001 times the unit (10-12 )

Table 1 Digit multipliers
Third digit Multiplier (this times the first two digits
gives you the value in Pico-Farads)
0 1
1 10
2 100
3 1,000
4 10,000
5 100,000
6 not used  
7 not used  
8 .01
9 .1

Example: A capacitor marked 104 is 10 with 4 more zeros or 100,000pF which is otherwise referred to as a 0.1uF capacitor.

Tolerance code is given by a single letter. Example a 103J is a 10,000 pF with +/-5% tolerance

Table 2 Letter tolerance code
Letter symbol Tolerance of capacitor
B +/- 0.10%
C +/- 0.25%
D +/- 0.5%
E +/- 0.5%
F +/- 1%
G +/- 2%
H +/- 3%
J +/- 5%
K +/- 10%
M +/- 20%
N +/- 0.05%
P +100% ,-0%
Z +80%, -20%

Exceptions: There is sometimes a letter-number-letter (like Z5U) code that gives additional information.
Example. A 224 Z5U would be a 220,000 pF (or .22 uF) cap with a low temperature rating of -10 deg C a high temperature rating of +85 Deg C and a tolerance of +22%,-56%.

    6 +105 deg. C D +/- 3.3%
    7 +125 deg. C E +/- 4.7%
        F +/- 7.5%
        P +/- 10.0%
        R +/- 15.0%
        S +/- 22.0%
        T +22%, -33%
        U +22%, -56%
        V +22%, -82%

There are some Capacitor colour codes – the last dot is the tolerance code where brown is +/-1% red +/-2% as in the resistor colour code with two exceptions black is +/- 20% and white is +/- 10% going backward the three dots to the left of the tolerance dot form the value in pF There will be two or three more colour dots before the value but they mean different things about temperature range and coefficient depend which one of three systems is used.

There are two more number systems seen on caps. The first one can be recognized as the EIA because it starts with an R.

R DM 15 F 471(R) J 5 O (C)

The above number means the following

R tells us this is an EIA code
DM is a dipped case style CM would be a molded case style
15 is the case size code – if anyone asks I will put up a table for this
F is the characteristic code from table 4
471R the R is a decimal point when used (not often) the
first two digits form the significant value and the third
is the multiplier thus, this is a 470pF part
J is the capacitance tolerance code as given in table 2 above thus J is a 5% part
5 is the DC working voltage in hundreds of volts (EIA only) thus 500V
O is the temperature range from table 5
C tells us the leads are crimped where a S would tell us they are straight.

This next one is a Military code example:

CM 15 B D 332 K N 3

CM is the case code – DM is a dipped case style CM would be a molded case style
15 is the case size code – if anyone asks I will put up a table for this
B characteristic code tells us it doesn’t have a drift specified (from table 4)
D is the Military voltage code from table 6
332 tells us that it is 3,300pF
K tells us from table 2 that this is a 10% part
N gives us our temperature range of -55 to 85 °C from table 5
3 The 3gives the vibration grade 3 tells us 20g at 10 to 2,000 hz for 12 hours (1 is 10G at 10 to 55 Hz for 4.5 hours)


Table 4 characteristic codes

Application Notes (Ceramic):

NPO: Has a very low dissipation factor and are very stable over wide variations in temperature, frequency, voltage, and time. NPO type capacitors are frequently used for precision timing, filtering, frequency setting, and tuning circuits.

X7R: Are used when some capacitance variation is allowed and the dissipation factor is not critical. X7R type capacitors are frequently used for bypass, decoupling, filtering, frequency discrimination, timing, DC voltage blocking, voltage transient suppression, instrumentation, computers, telecommunications, and automotive electronics.

Z5U: Dielectrics have the highest capacitance for their size. Z5U type capacitors have applications in bypass, decoupling, transient suppression, computers, and telecommunications.
