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

Product Description The 56 Ohm 1/4 Watt Resistor is a high-quality passive component designed for low-resistance circuit applications such as signal termination, current sensing, and protection. Featuring a 5% tolerance, these resistors ensure stable electrical behavior in standard prototyping and repair tasks. With a standard 0.25W power rating, it provides a reliable resistive barrier for low-voltage signal conditioning and is a staple in both educational kits and professional electronic hardware.
