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

Product Description The 4.7 Ohm 1/4 Watt Resistor is a high-performance passive component specifically designed for low-impedance circuit applications such as current sensing, inrush protection, and power filtering. Featuring a 5% tolerance, these resistors ensure stable electrical behavior in standard prototyping and repair tasks. With its standard 0.25W power rating, it provides a reliable resistive barrier for low-voltage signal conditioning and is a staple in compact electronic hardware designs.
