8.2k Ohm 0.25W Carbon Film Resistor - 5% Tolerance (Pack of 5)

Product Description 

The 8.2k Ohm 1/4 Watt Resistor is a highly versatile passive component essential for electronic signal conditioning and circuit biasing. These carbon film resistors feature a 5% tolerance, making them a reliable choice for pull-up/pull-down networks and RC timing stages. With a standard 0.25W power rating, they provide stable performance in a compact axial package, ideal for high-impedance analog sensor circuits and digital logic stabilization in both hobbyist and professional projects.

Key Features
