3.3K Ohm 1/4W Resistor ±5% – Carbon Film Through-Hole Resistor – 1 Pc
VAT inclusive; Computed calculations added locally.
Overview
The 3.3K Ohm resistor is a commonly used fixed-value component for controlling current and voltage in electronic circuits. With a nominal resistance of 3.3KΩ (3300Ω) and a 1/4W (0.25W) power rating, it is suitable for a wide range of low-power electronic applications.
Its axial through-hole construction makes it easy to install on standard PCBs, breadboards, and prototype circuits. The ±5% tolerance provides a practical balance between general-purpose accuracy and cost for everyday electronics work.
This single-piece resistor can be used in microcontroller projects, sensor circuits, transistor stages, LED circuits, voltage dividers, signal conditioning, and pull-up or pull-down networks.

Product Technical Information
Technical Details
The 3.3K Ohm 1/4W Carbon Film Resistor is a small, non-polarized passive component designed for general-purpose circuit applications. Its 3300Ω resistance value is useful for limiting current, establishing voltage levels, and controlling signal behavior.
The resistor uses a standard axial lead configuration, allowing it to be inserted directly into breadboards or soldered onto through-hole PCBs. It can also be used in combination with other resistors to create specific resistance values or voltage-divider ratios.
Features
- Resistance value: 3.3KΩ
- Equivalent to 3300Ω or 3K3
- 1/4W (0.25W) power rating
- ±5% tolerance
- Carbon film construction
- Axial through-hole design
- Non-polarized component
- Easy to use on breadboards and PCBs
- Suitable for general-purpose electronics
Applications
- Voltage divider circuits
- Current limiting
- Pull-up and pull-down networks
- Arduino and microcontroller projects
- ESP32 and Raspberry Pi projects
- Sensor interfaces
- Signal conditioning
- Transistor circuits
- LED circuits
- Switching and control circuits
- DIY electronics and prototyping
How to Use
- Identify the required 3.3KΩ resistance value.
- Insert the resistor into the breadboard or PCB.
- Since it is non-polarized, either lead can be connected in either direction.
- Ensure the circuit does not exceed the resistor's 0.25W power rating.
- For voltage-divider or current-limiting applications, calculate the expected current and resistor power before operation.
Important Notes
- This listing is for 1 piece only.
- 3.3KΩ is equal to 3300Ω.
- The ±5% tolerance means the actual resistance may vary around the nominal 3.3KΩ value.
- The maximum power rating is 0.25W; exceeding this rating can cause overheating or permanent damage.
- Resistors can become hot when dissipating significant power.
- The physical appearance and color bands may vary slightly between batches.
- Verify the resistor value before installation when working with precision-sensitive circuits.
Package Includes
- 1 × 3.3K Ohm 1/4W Carbon Film Resistor
