2.2M Ohm Resistor 1/4 Watt (Pack of 10)

The 2.2M Ohm 1/4 Watt Resistor is a fixed-value passive electronic component designed to control current flow, divide voltage, bias transistors, and stabilize signals in electronic circuits. With a resistance value of 2.2 megaohms (2,200,000Ω) and a power rating of 0.25 watts (1/4W), it is ideal for high-resistance and low-current applications in electronics, embedded systems, sensor circuits, and educational projects.

Resistors are essential components in electronic circuit design, helping regulate current and establish proper voltage levels for reliable operation. The 2.2MΩ resistor is commonly used in pull-up and pull-down networks, voltage divider circuits, transistor biasing, RC timing circuits, signal conditioning applications, and high-impedance sensor interfaces. Its very high resistance value makes it particularly useful in circuits where minimal current flow is required.

Manufactured using high-quality carbon film or metal film technology, these resistors offer stable resistance values, low noise characteristics, and dependable long-term performance. Their standard through-hole axial-lead design allows easy installation on breadboards, prototype boards, and printed circuit boards (PCBs), making them suitable for both experimentation and permanent circuit assembly.

Since the resistor is non-polarized, it can be connected in either direction without affecting circuit functionality, simplifying installation and use.

Working Principle

A resistor opposes the flow of electrical current in a circuit. According to Ohm’s Law (V = IR), it creates a voltage drop proportional to the current passing through it. The high resistance value of 2.2MΩ allows only a very small amount of current to flow, making it suitable for high-impedance circuits, timing networks, and signal processing applications.
