Resistors are quite popular components in our electronic project, it is used for regulating voltage, measuring current, setting an operating point, dividing signals in electroniccircuits. An resistor is a device took with two terminals which made of Resistor element and insulator the current. As we known, the resistors can be divided to many types, like surface mount resistors, through hole resistodrs and so on. Here we mainly introduce through hole resistor.

RN55C4872BRSL application field and working principle

RN55C4872BRSL is a very common through hole resistor. Generally speaking, RN55C4872BRSL is a kind of surface mount device (SMD), its full name is 0805 47KOhm Thick film resistor. It owns properties of small size, easy operation, low cost and accurate superiority. It’s widely used in electronic circuit with inside resistance values and may be used in a variety of the application field. For instance, its main application is that circuit protection, power divider and so on. As usual, the RN55C4872BRSL resistor is called a resistor to prove electricity is not allowed to pass. It hastwo pins with and made of resistor elements and insulator. It is quite similar a diode and triode. When two pins connect, the electricity was not allowed to pass to another pin, the silicon chip resistors will be a barrier and consumer the current in the process. When electricity passes the resistor, it will cause the resistor heat. The larger the heat, the more current integrated.

So, we should noticed that the resistor should not be too large otherwise it cannot control the flow of current properly. And we should pay more attention to the other color of the resistor. The colored may indicate the resistance value and tolerance of the resistor. The three colorful lines on the resistor will be red, white and blue. The red coding indicates the first digit of the resistor in Ohms. The second digit indicates the second color, either white or yellow. Then the when the third digit which is represented by the black. The fourth and fifth digits are indicated by the gold coin.

Conclusion

In summary, RN55C4872BRSL surface mount resistor features small size, low cost and accurate superiority, it owns wide applications such as power divider, battery holder and etc. According to the color coding, we can know the resistance of the resistor in a more efficient way.
