68K Ohm Resistor 1/4 Watt (Pack of 10)

The 68K Ohm 1/4 Watt Resistor is a fixed-value passive electronic component designed to control current flow, divide voltage, bias transistors, and protect sensitive electronic components in electrical and electronic circuits. With a resistance value of 68,000 ohms (68KΩ) and a power rating of 0.25 watts (1/4W), it is widely used in low-current electronic applications, embedded systems, Arduino projects, and educational electronics experiments.

Resistors are essential components in circuit design and help maintain proper operating conditions by regulating current and voltage levels. The 68KΩ resistor is commonly used in voltage divider networks, pull-up and pull-down resistor configurations, transistor biasing circuits, signal conditioning applications, sensor interfacing, and RC timing circuits. Its relatively high resistance value makes it particularly useful for low-current signal processing and control circuits.

Manufactured using high-quality carbon film or metal film technology, these resistors provide stable resistance values, low electrical noise, and excellent long-term reliability. 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.

As a non-polarized component, the resistor can be connected in either direction without affecting circuit performance, ensuring simple installation and easy integration into electronic designs.
