180k Ohm 1/4 Watt Resistor (5 Pcs)

The 180k Ohm 1/4 Watt Resistor (5 Pcs) is a passive electronic component used in almost all types of electronic circuits to control current flow, divide voltage, and stabilize signal levels. It has a fixed resistance value of 180 kilo-ohms (180kΩ) and a power rating of 0.25 watts (1/4 watt), making it suitable for low-power general-purpose electronic applications.

A resistor works by opposing the flow of electric current in a circuit. In this case, the 180kΩ value provides high resistance, which allows only a very small current to pass through. This makes it especially useful in circuits where signal control, voltage sensing, or biasing is required without loading the circuit.

This resistor is commonly used in signal conditioning circuits, transistor bias networks, voltage divider circuits, and protection circuits. It is also widely used in DIY electronics projects, Arduino circuits, PCB designs, and educational experiments where accurate resistance values are required.

The 1/4 watt power rating means the resistor can safely handle up to 0.25 watts of electrical power. It is designed for low-power applications and should not be used in high-current or high-power circuits.

This pack contains 5 identical resistors, making it suitable for small projects, circuit repairs, and prototyping work. Its compact axial-lead design allows easy insertion into breadboards and soldering onto PCBs.

Working Principle

The resistor operates based on Ohm’s Law (V = IR):

• When voltage is applied, the resistor limits current flow according to its resistance value.

• A higher resistance like 180kΩ results in very low current flow.

• Electrical energy is partially converted into heat during operation.

This behavior allows precise control of electrical signals in circuits.
