  • 150 ohm Resistor
A 150-ohm resistor is a standard electronic component used to limit electrical current and drop voltage in a circuit.

Technical Specifications
  • Resistance Value: 150 ohms (150Ω or 150R) [1, 2]
  • Common Color Code (4-band): Brown, Green, Brown, Gold (for 5% tolerance) [1]
  • Common Color Code (5-band): Brown, Green, Black, Black, Brown (for 1% tolerance) [1]
  • Standard Power Rating: 1/4 Watt (0.25W) is most common for general DIY and breadboarding. [1]
Common Uses
  • LED Protection: Acts as a current limiter when powering red, yellow, or orange LEDs (around 2V forward drop) from a 5V source to keep current near 20mA. [1, 2]
  • Voltage Dividers: Used alongside other resistors to step down voltage levels and create reference signals. [1]
  • Transistor Biasing: Helps set proper operating points in amplifier circuits.
