Each resistor measures approximately 9 mm in body length and 3 mm in body diameter. These 10-ohm, 1/2-watt carbon film resistors provide a stable replacement for original components often found in filament circuits, cathode bias networks, and power supply sections of vintage radios from manufacturers such as RCA, Philco, and Zenith. Carbon film construction offers reliable performance with a 5% tolerance, serving as an effective alternative to aging carbon composition parts while fitting standard chassis layouts, Pkg of 5.
