3.3K OHM ±5% 1/4W Through Hole Carbon Film Resistor (Axial Leaded)

Resistance: 3.3K Ohm (3K3) | Tolerance: ±5% | Power Rating: 1/4W (0.25W) | Type: Carbon Film Through Hole | Color Code: Orange – Orange – Red – Gold

The 3.3K Ohm 1/4W Through Hole Resistor is one of the most widely used passive electronic components in both hobbyist and professional circuit design. With a resistance value of 3,300 Ohms (3.3KΩ) and a tight ±5% tolerance, this resistor delivers reliable performance across a wide range of general-purpose analog and digital applications.

Power & Safety: Rated at 1/4 Watt (0.25W), it safely handles voltages up to 350V, making it suitable for standard low-power circuit designs without risk of thermal failure.

Construction: This is a carbon film, axial-leaded resistor — the most popular resistor type for through-hole PCB assembly, breadboarding, and prototyping. The tin-plated copper leads ensure excellent solderability and strong mechanical hold on PCBs.

Color Band Code: Orange – Orange – Red – Gold (3 – 3 – ×100 – ±5%)

Common Applications:

• Pull-up and pull-down resistors in microcontroller circuits (Arduino, ESP32, Raspberry Pi)

• Current limiting for LEDs

• Voltage divider networks

• Signal conditioning and filtering

• RC timing circuits

• Sensor interfacing circuits
