Las resistencias SMD pueden tener 3 o 4 dígitos , Vamos a ver como se lee su valor.
También si tienen números y letras (lo cual se complica un poquito mas)
Las siglas SMD se refiere a Surface Mounted Device, que en inglés significa dispositivo de montaje superficial y se refiere tanto a una forma de encapsulado de componentes electrónicos, como a los equipos construidos a partir de estos componentes
Tenemos resistencias SMD de 3 dígitos, la tolerancia en esta codificación es de 5%
La resistencia SMD de 4 dígitos (valores de precisión menores a 100 ohms) tiene una tolerancia de 1% y se usa la letra R para representar la coma.
También puede ser que el tercer dígito (multiplicador) sea una letra , llamado codificación EIA-96
la tolerancia generalmente es del 1%
Algunos ejemplos con 3er dígito con letra:
04E = 1070000 Ω ± 1%
33H = 2150 Ω ± 1%
01A = 100 Ω ± 1%
84Z = 0.732 Ω ± 1%
38C = 24300 Ω ± 1%
92Z = 0.887 Ω ± 1%
18D = 150000 Ω ± 1%
nota: Siempre es recomendable medir con un tester la resistencia para comprobar su valor.
Y por ultimo , el ultimo dato de estas resistencias , es la potencia que pueden disipar , que obviamente tiene que ver con el tamaño de la R.
El siguiente cuadro nos da una aproximación de los valores y los distintos tipos de resistencias por código 0201,0402,0603,0805,1206,1210,2010,2512
L= Largo
W= Ancho

SMD resistors can have 3 or 4 digits. Let's see how their value is read.
Also if they have numbers and letters (which is a little more complicated)
The acronym SMD refers to Surface Mounted Device, which in English means surface mounting device and refers to both a form of encapsulation of electronic components and equipment built from these components.
We have 3 digit SMD resistors, the tolerance in this coding is 5%
The 4-digit SMD resistor (precision values less than 100 ohms) has a tolerance of 1% and the letter R is used to represent the comma.
It may also be that the third digit (multiplier) is a letter, called EIA-96 encoding
tolerance is generally 1%
Some examples with 3rd digit with letter:
04E = 1070000Ω ± 1%
33H = 2150Ω ± 1%
01A = 100Ω ± 1%
84Z = 0.732Ω ± 1%
38C = 24300Ω ± 1%
92Z = 0.887Ω ± 1%
18D = 150000Ω ± 1%
Note: It is always advisable to measure the resistance with a tester to check its value.
And finally, the last piece of information about these resistors is the power they can dissipate, which obviously has to do with the size of the R.
The following table gives us an approximation of the values and the different types of resistances by code 0201,0402,0603,0805,1206,1210,2010,2512
L= Length
W= Width
H = High
