Overview
The Motorola 6-6090 is a vintage carbon composition resistor designed for high-reliability electronics applications. This fixed resistor features a 470Ω nominal resistance value with ±10% tolerance and a 0.5W power dissipation rating. The Motorola 6-6090 represents classic resistor technology widely used in consumer electronics, industrial control systems, and audio equipment from the 1960s through 1980s.
Key Features
- Carbon composition construction for stable long-term performance in legacy systems
- 470Ω nominal resistance value with ±10% tolerance band
- 0.5W power rating suitable for low-to-moderate current applications
- Axial lead termination for through-hole PCB mounting
- Vintage file pack units—original sealed inventory from Motorola manufacturing
- Ideal for equipment restoration, vintage audio amplifier repair, and historical electronics preservation
Technical Specifications
Carbon composition resistors like the Motorola 6-6090 provide excellent impulse handling, low noise, and reliable performance over decades of operation. They are commonly found in vintage radios, amplifiers, test equipment, and industrial control modules. The ±10% tolerance is typical for carbon composition technology and suitable for non-precision applications where component drift is acceptable within the tolerance band.
Typical Applications
- Vintage vacuum tube and transistor radio repair
- Audio amplifier and tuner restoration
- Industrial process control equipment from the 1960s–1980s
- Test and measurement instrument calibration
- Electronic hobby projects requiring authentic period components
