1.2K Ohm Resistor 1/4 Watt (Pack of 10)

The 1.2K Ohm 1/4 Watt Resistor is a fixed-value passive electronic component used to control current flow, divide voltage, bias transistors, and protect sensitive electronic components in electrical and electronic circuits. With a resistance value of 1,200 ohms (1.2KΩ) and a power rating of 0.25 watts (1/4W), it is widely used in electronics projects, embedded systems, Arduino applications, and educational circuit development.

Resistors are fundamental components in electronic circuits and play an important role in maintaining proper current and voltage levels. The 1.2KΩ resistor is commonly used in LED current-limiting circuits, voltage divider networks, pull-up and pull-down resistor configurations, transistor biasing circuits, sensor interfaces, and signal conditioning applications. It helps ensure reliable circuit operation while protecting components from excessive current.

Manufactured using high-quality carbon film or metal film technology, these resistors provide 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 prototyping and permanent circuit assembly.

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