3.3K Ohm Resistor 1/4 Watt (Pack of 10)

The 3.3K Ohm 1/4 Watt Resistor is a fixed-value passive electronic component used to regulate current flow, divide voltage, bias transistors, and protect sensitive electronic components in electrical and electronic circuits. With a resistance value of 3,300 ohms (3.3KΩ) 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 circuit design and play an important role in controlling current and voltage levels. The 3.3KΩ resistor is commonly used in pull-up and pull-down resistor networks, voltage divider circuits, transistor biasing applications, sensor interfaces, LED control circuits, and signal conditioning systems. Its resistance value makes it suitable for both digital and analog circuit applications.

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

Since the resistor is non-polarized, it can be connected in either direction without affecting its functionality, allowing quick and easy integration into electronic circuits.
