100K Ohm Resistor 1/4 Watt (Pack of 10)

The 100K 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 100,000 ohms (100KΩ) and a power rating of 0.25 watts (1/4W), it is widely used in low-current and high-impedance applications such as embedded systems, Arduino projects, sensor circuits, and electronic prototyping.

Resistors are essential components in electronics that help regulate voltage and current to ensure proper and safe circuit operation. The 100KΩ resistor is commonly used in voltage divider networks, pull-up and pull-down resistor configurations, transistor biasing circuits, RC timing circuits, signal conditioning applications, and sensor interfacing circuits. Its high resistance value makes it suitable for controlling small currents and managing signal levels in sensitive circuits.

Manufactured using high-quality carbon film or metal film technology, these resistors provide stable resistance values, low noise performance, and reliable long-term durability. Their standard through-hole axial-lead design allows easy installation on breadboards, prototype boards, and printed circuit boards (PCBs), making them ideal for both learning and professional electronics work.

Since the resistor is non-polarized, it can be connected in either direction without affecting its function, making circuit assembly simple and flexible.
