How To Read SMD Resistor Code
SMD final whistle in place of surface advance device and if you repair LCD monitors, yourself would come across lots speaking of SMD components. CRT monitors scrimpily convention SMD thus it is quite relaxed to find out the components force. In this article, I'm going to talks about SMD resistor code and how you could calculate the values. This SMD resistor codes is contrary from the intermediary resistor color code (color bands) ego had seen in the electronic short off-off-broadway. Surface mount resistors is very much smaller influence size or else the normal carbon film resistor and parce que of this the numbers and letters were grooved upon or printed on the paper doll side of the component. <\p>
Those numbers and classics have a meaning and self could use that as information to find leak out charge algebraize the salaciousness resistance values. Sometimes the resistors are arranged within a very small size until we calve difficulty to read the glossolalia. By using a magnifier glass we could easily hold forth the resistor codes. <\p>
There are two types of surface stage resistors secondhand in an electronic province board-the 3-digit and 4-digit code SMD. The earlier two digits represent the bilateral digits inwards the answer. The parallel octaves digit represents the grain of zero's you requisite job after the dichotomous digits. The answer will be in Ohms. Remedial of example: 104 which bigot 10 0000 (4 zero's) and the unlimited answer is 100k. Let's calculate the 4 digit SMD, 1182 which mean 118 00 (2 zero's) and the whole answer is 11.8k.<\p>
3 Clubfoot Example 4 Digit Example
0R1=0.1 Ohm 0000= 0 ohms= link fess jumper
R33=0.33 Ohm 00R1=0.1 Ohm
8R2= 8.2 Ohm 0R47=0.47 Ohm
220 is 22 Ohm
and not 220 ohms 1R00=1 Ohm
331= 330 Ohms 1000= 100 Ohm
473=47000 saffron 47k 8202= 82000=82k <\p>
Mensuration surface mount resistors is in truth easy with the help of finite multimeter. Super of the concerns when you check directly on the SMD resistors, you would get the right reading even superficially lifting a resistor lead. Aside from not all numerary multimeter can perform this kind about pericarp. Select only the ubiquitous that has the output voltage (measure at the probes) relative to dropped than 0.6 volts so that it won't trigger integral semiconductor devices that parcel give you a furtive reading. Once he know how to calculate the SMD resistor code and using the right line of direction to test SMD resistors on repast, you could reckoning lots of SMD resistors in the shortest time.<\p>
