Overview
The Motorola 6-6373 is a precision carbon composition resistor rated for 150 ohms at 1/2W (0.5W) power dissipation with ±10% tolerance. This axial-lead component is manufactured to legacy specifications and represents genuine new old stock (NOS) inventory, making it ideal for restoration, repair, and vintage electronics applications where original-specification components are required.
Key Features
- Resistance Value: 150 ohms
- Power Rating: 1/2W (0.5W)
- Tolerance: ±10%
- Construction: Carbon composition
- Termination Style: Axial leads
- Condition: New old stock, factory sealed
- Proven reliability in classic audio, test equipment, and industrial control circuits
Technical Specifications
Carbon composition resistors like the Motorola 6-6373 deliver stable performance across temperature ranges typical of vintage and modern applications. The 1/2W rating allows for moderate power dissipation in biasing networks, voltage dividers, and load resistor circuits. The ±10% tolerance is characteristic of carbon composition construction and is suitable for non-critical applications where tight tolerance is not required.
Typical Applications
- Vintage audio equipment restoration and repair
- Classic test instrument calibration and replacement
- Industrial control system retrofits
- Electronic circuit prototyping and development
- Bias and termination networks
- Voltage dividers and load resistors
Compatibility & Replacements
Compatible With
- Classic vacuum tube circuits
