47k Ohm 0.25W Carbon Film Resistor - 5% Tolerance (Pack of 5)

Product Description The 47k Ohm 1/4 Watt Resistor is a highly versatile passive component essential for electronic prototyping and circuit design. With a resistance of 47kΩ and a standard 1/4W power rating, these resistors are frequently used for pull-up/pull-down logic, signal conditioning, and as current limiters in 5V-12V circuits. Their carbon film construction ensures stable performance across various temperatures, making them a reliable choice for both student projects and professional engineering.
