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

The 10M Ohm 1/4 Watt Resistor is a fixed-value passive electronic component used in electronic circuits to control current flow, divide voltage, bias transistors, and stabilize signals. With a very high resistance value of 10,000,000 ohms (10MΩ) and a power rating of 0.25 watts (1/4W), it is mainly used in ultra-low current and high-impedance applications such as sensing circuits, timing circuits, and precision electronic measurements.

Resistors are fundamental components in electronics and are used to ensure proper voltage and current levels in a circuit. The 10MΩ resistor is commonly used in voltage divider networks, pull-up or pull-down circuits, leakage current sensing, RC timing circuits, sensor interfacing, and high-impedance input circuits. It is especially useful where extremely small currents need to be measured or controlled.

Manufactured using carbon film or metal film technology, these resistors provide stable resistance values, good reliability, and low noise performance. Their standard through-hole axial-lead design allows easy mounting on breadboards, prototype boards, and printed circuit boards (PCBs), making them suitable for both testing and permanent circuit applications.

Since it is a non-polarized component, it can be connected in either direction, simplifying circuit design and assembly.
