68 Ohm 0.25W Carbon Film Resistor - 5% Tolerance (Pack of 5)

Product Description The 68 Ohm 1/4 Watt Resistor is a reliable passive component designed for low-resistance circuit requirements such as current sensing, signal termination, and LED protection. Featuring a 5% tolerance, these resistors ensure stable performance for general-purpose prototyping and electronic repair. With a standard 0.25W power rating, they provide a stable resistive barrier for managing voltage drops in both educational kits and professional-grade electronic hardware.

Key Features
