680K Ohm Resistor 1/4 Watt (Pack of 10)

The 680K 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 680,000 ohms (680KΩ) and a power rating of 0.25 watts (1/4W), it is commonly used in low-current, high-impedance, and signal processing applications such as embedded systems, Arduino projects, sensor circuits, and educational electronics.

Resistors are essential components in electronics that help regulate voltage and current to ensure proper and safe circuit operation. The 680KΩ resistor is widely used in voltage divider networks, pull-up and pull-down resistor configurations, transistor biasing circuits, RC timing circuits, sensor interfacing, and signal conditioning applications. Its high resistance value makes it ideal for circuits where only a very small current is allowed to flow.

Manufactured using high-quality carbon film or metal film technology, these resistors offer stable resistance values, low noise characteristics, and reliable 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 electrical behavior, making it easy to use in various circuit designs.
