220K Ohm Resistor 1/4 Watt (Pack of 10)

The 220K Ohm 1/4 Watt Resistor is a fixed-value passive electronic component used to control current flow, divide voltage, bias transistors, and stabilize signals in electronic circuits. With a resistance value of 220,000 ohms (220KΩ) and a power rating of 0.25 watts (1/4W), it is widely used in low-current applications, embedded systems, Arduino projects, sensor circuits, and educational electronics experiments.

Resistors are essential components in electronic circuit design and play a crucial role in maintaining proper voltage and current levels. The 220KΩ resistor is commonly used in voltage divider networks, pull-up and pull-down resistor configurations, transistor biasing circuits, RC timing networks, signal conditioning applications, and sensor interfacing. Its high resistance value makes it ideal for applications requiring minimal current flow and stable signal control.

Manufactured using high-quality carbon film or metal film technology, these resistors provide excellent electrical stability, low noise performance, and reliable long-term operation. Their standard through-hole axial-lead design allows easy installation on breadboards, prototype boards, and printed circuit boards (PCBs), making them suitable for both development and permanent circuit applications.

As a non-polarized component, the resistor can be connected in either direction without affecting its functionality, simplifying installation and circuit assembly.

Working Principle

A resistor limits the flow of electrical current by providing resistance within a circuit. According to Ohm’s Law (V = IR), it creates a voltage drop proportional to the current flowing through it. The 220KΩ resistor is commonly used where high resistance is required for voltage division, timing functions, and signal conditioning while allowing only a small amount of current to pass.
