Description
Technical Specifications
The 120 Ohm 1/4W 5% Resistor Kit contains 50 pieces of 120 ohm resistors, suitable for applications requiring a specific resistance value. These resistors are used to limit the flow of current in electronic circuits, ensuring that components do not exceed their power limits. The 120 ohm resistor is particularly useful in projects that require a certain amount of resistance to regulate the flow of current or to create voltage dividers.
Resistors are manufactured with a 5% tolerance, meaning the actual value can vary by up to 5% from the nominal value. They can handle a maximum power of 1/4 Watt, making them suitable for applications that do not require a high current flow. Their application is widely used in Arduino and other microcontroller projects to regulate electrical current or to create voltage dividers.
It is important to verify the resistance value before using it, using a measuring tool such as a multimeter. Additionally, it is essential to correctly connect the resistor to the circuit to avoid damage to components or the microcontroller.
