Fingerprint Sensor AS608 - A Beginner's Guide
One touch can replace keys. This project uses an optical fingerprint sensor to enroll users and then grant access with a quick scan.
read tutorial →Resistor Through-Hole 2.2K ohm 5% 1/4W is a special type of resistor that is used in the electrical and electronic setups in many different areas and helps to regulate the flow of electricity. Let us first try to understand what we mean by a resistor.
As the name implies, a resistor prevents electricity from flowing through a circuit. By doing this, it effectively regulates the electric current flow and only permits necessary electricity to flow. It prevents strong electric currents from damaging the other gadgets. It operates based on Ohm's law.
It means the way it will be mounted on the PCB boards. These are mounted in the holes that are made over the PCD boards and have metal legs.
This is the amount of resistance that the electric current can encounter from this resistor. 2200 ohms is the value.
Tolerance means how much variation can be seen in the resistance that is mentioned in it. In this case, it is 2200. So, resistance can vary between 2090 and 2310 ohms.
It is the amount of power that can be sent out of the circuit without damaging the appliances or the circuit. It can cover 0.25 watts.
Ohm's law governs how it operates. The voltage supplied will determine how much resistance there is to the current. Ohm's law allows us to measure that. When current passes through the resistor, it restricts the current flow and results in a voltage drop.
We can use Resistor Through-Hole 2.2K ohm 5% 1/4W in the LED bulbs, voltage divider in the electronic circuits. And many other areas where there is a need to control the excess electric or there are light devices connected in a circuit. It is used in Arduino, Raspberry Pi, microcontrollers, and other DIY projects.
The 2.2K ohm 5% 1/4W resistor through-hole is a small yet useful component used in electrical systems. Additionally, it is crucial for the circuit. It is essential for regulating a circuit's electric current. Circuitrocks offers the highest quality resistor through-hole 2.2K ohm 5% 1/4W. Other products that are extremely important for electric circuits can also be found on the internet at the official website of Circuitrocks.
ΩMG! You're not going to be able to resist these handy resistor packs! Well, axially, they do all of the resisting for you!
This is a 25 Pack of 2.2K Ω Resistors. More specifically, they are carbon film, through-hole axial type, with 1/4 Watt max dissipation, 300V max voltage, 5% precision resistors. Whew! These are super common and great for use in any kit, breadboard, perf-board, or other project. We got ones with 0.4mm thick wires so they plug in nicely into solder-less breadboards.
