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

The 1M 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 1,000,000 ohms (1MΩ) and a power rating of 0.25 watts (1/4W), it is ideal for high-resistance and low-current applications in electronics, embedded systems, Arduino projects, sensor circuits, and educational experiments.

Resistors are fundamental components in electronic circuit design and help regulate current and voltage levels for reliable operation. The 1MΩ resistor is commonly used in pull-up and pull-down resistor networks, voltage divider circuits, transistor biasing, RC timing circuits, signal conditioning applications, and high-impedance sensor interfaces. Its high resistance value allows only a very small amount of current to flow, making it suitable for precision signal and timing applications.

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

As a non-polarized component, the resistor can be connected in either direction without affecting circuit functionality, simplifying installation and use in a wide range of electronic projects.
