Overview
The Motorola 6-6069 is a vintage carbon composition resistor pack rated at 2.2kΩ with 0.5 watts power dissipation and ±10% tolerance. Carbon composition resistors are made by mixing carbon particles with a binder molded into a cylindrical shape, and then baked. This construction delivers rugged performance in surge-prone circuits and retro tube audio applications where solid-state alternatives may be less suitable.
Key Features
- Resistance Value: 2.2 kΩ (2,200 ohms)
- Power Rating: 0.5W (500 milliwatts)
- Tolerance: ±10%
- Axial lead package for through-hole mounting
- Suitable for protection of circuits (surge or discharge protection), current limiting, high voltage power supplies, high power or strobe lighting, and welding applications.
- Vintage Motorola manufacturer pack — tested and in original box
Technical Specifications
Operating temperature range: -55 to +125°C; working voltage: 350V. The operating temperature range is between around -40 to 150°C, however the resistor derate above 70°C. These resistors exhibit the expected high temperature coefficient typical of carbon composition construction and are suitable for vintage equipment restoration and legacy system repair.
Typical Applications
- Vintage tube radio and audio amplifier restoration
- Retro television and vintage broadcast equipment repair
- Surge protection and discharge circuits
- RF and tuning circuits in classic receivers
- Bias and coupling circuits where small size and high-energy tolerance are required
- Industrial and medical equipment from the 1960s–1980s era
