Overview
The Motorola 6-6414 is a fixed carbon composition resistor rated at 270K Ohms with 1/2 Watt power dissipation and ±10% tolerance. Featuring axial leads, this vintage resistor is manufactured to Motorola’s proven specifications and remains a preferred choice for electronic restoration, vintage radio repair, and precision analog circuit design. Supplied in new old stock (NOS) condition, this component is fully functional and ready for immediate deployment in your projects.
Key Features
- Resistance: 270K Ohms with ±10% tolerance
- Power Rating: 1/2 Watt (0.5W) continuous dissipation
- Construction: Carbon composition element
- Termination: Axial leads for through-hole PCB mounting
- Condition: New Old Stock (NOS) – unused, original packaging
- Manufacturer: Motorola, USA-manufactured precision component
Technical Specifications
Carbon composition resistors like the Motorola 6-6414 offer excellent frequency response characteristics and inherent noise suppression properties, making them ideal for analog circuits, audio applications, and high-frequency circuits where film resistors may introduce unwanted artifacts. The ±10% tolerance provides adequate precision for non-critical bias, coupling, and filtering applications while maintaining classic component authenticity in vintage equipment restoration.
Typical Applications
- Vintage radio, amplifier, and audio equipment restoration
- Precision analog circuit biasing and coupling networks
- Vintage test equipment and vintage measuring instrument repair
- Audio frequency signal conditioning and filtering
- Resistor network component in legacy industrial electronics
- Museum-grade restoration and period-correct equipment preservation
Compatibility & Replacements
Compatible With
- Vintage Motorola amplifier and receiver designs
- 1960s–1980s audio equipment using carbon composition elements
- Standard 5mm pitch through-hole PCB layouts
- Analog circuits requiring low-noise biasing networks
Replaces / Drop-In Replacement For
The Motorola 6-6414 is a direct replacement for other manufacturers’ 270K Ohm, 1/2W carbon composition resistors with ±10% tolerance and axial leads. Modern carbon film or metal film resistors rated 270K/1/2W/±5% or ±1% can serve as functional equivalents in most applications, though carbon composition construction is preferred in audio circuits for lowest noise characteristics.
Works With
- Through-hole soldering and hand assembly techniques
- PCB breadboarding for prototyping and troubleshooting
- Vintage component test equipment and multimeters
- Standard lead bending and forming tools
