Overview
The Motorola 6-6433 is a fixed carbon composition resistor rated at 2.2M Ohm with 1/2W power handling and ±10% tolerance. This axial-lead through-hole component features U.S. construction and is optimized for high-reliability applications in industrial electronics, test equipment, and vintage audio/video restoration. As NOS (New Old Stock), it remains unused and fully functional.
