Overview
The Motorola 6-6460 carbon composition resistor delivers stable, fixed resistance performance in a compact axial-lead format. Rated at 1.5 megohm (1.5M Ω) with 1/2 watt power handling and ±10% tolerance, this NOS (new old stock) component is ideal for legacy equipment restoration, vintage electronics repair, and applications requiring reliable mid-to-high resistance values. Manufactured in the United States by Motorola, this resistor combines proven carbon composition technology with decades of proven reliability.

Technical Specifications
Carbon composition resistors provide stable DC performance with minimal noise, making them suitable for audio coupling, biasing, and general-purpose circuit applications. The 1.5M Ω value falls within high-resistance applications, such as input impedance matching, bleeder networks, and sensor circuits.
- Operating Temperature Range: −55°C to +155°C (typical for carbon composition)
- Temperature Coefficient: ±1000 ppm/°C (typical)
- Frequency Response: DC to low RF
- Insulation Resistance: >1000 MΩ at 500V DC
Typical Applications
- Legacy equipment restoration and repair
- Vintage radio and audio amplifier restoration
- Input impedance and biasing networks
- Sensor and measurement circuit support
- Bleeder networks and voltage dividers
- Collector or gate bias resistors in amplifier stages
