12K Ohm 1/4 Watt Resistor (Pack of 10)

The 12K Ohm 1/4 Watt Resistor is a fixed-value passive electronic component used to control current flow, divide voltage, bias transistors, and protect electronic circuits. With a resistance value of 12,000 ohms (12KΩ) and a power rating of 0.25 watts (1/4W), it is widely used in electronic devices, embedded systems, Arduino projects, and educational applications.

Resistors are fundamental components in circuit design and play an important role in regulating electrical current and maintaining stable circuit operation. The 12KΩ resistor is commonly used in voltage divider networks, pull-up and pull-down circuits, transistor biasing, sensor interfacing, signal conditioning, and timing applications.

These resistors are typically manufactured using carbon film or metal film technology, providing stable resistance values, low noise characteristics, and reliable long-term performance. Their standard axial-lead design makes them easy to install on breadboards, prototype boards, and printed circuit boards (PCBs).

As a non-polarized component, the resistor can be connected in either direction, making circuit assembly simple and convenient for students, hobbyists, and professional electronics engineers.
