5k Ohm Resistor
Common Value Resistor for Precision Circuits and Signal Conditioning
The 5k ohm resistor is a standard resistance value used in electronic circuits for voltage dividers, pullup/pulldown networks, sensor interfacing, and signal conditioning. While less common than 10k or 1k, it serves specific roles where moderate resistance is required for current limiting and biasing applications.
Standard Resistance Value - Used in voltage divider and bias circuits
Wide Availability - Available in various power ratings and tolerances
Common power ratings: 1/4W (0.25W) and 1/2W (0.5W) for through-hole types.
Common tolerances: ±1 (metal film), ±5% (carbon film).
Always check the power rating of your resistor to ensure it can handle the circuit's current without overheating [citation:5].
Color Code and Identification
For a 4-band resistor with ±5% tolerance, the color code is:
- 1st band: Green (5)
- 2nd band: Black (0)
- 3rd band (Multiplier): Red (×100) [citation:3]
- 4th band (Tolerance): Gold (±5%)
This gives a value of 5 × 100 5000 ohms 5kΩ [citation:7].
For a ±1% tolerance version, the 4th band is Brown instead of Gold.
