Resistor 0.5W 2.2K ohm (5 pcs)

The Resistor 0.5W 2.2K ohm is a through-hole fixed resistor with a resistance of 2.2 kΩ and a power rating of 0.5 W, sold in a pack of 5. 2.2 kΩ is a common pull-up value for the I2C SDA and SCL lines and a good base resistor for small transistors driven from microcontroller pins, so it is a useful value to keep in your parts drawer.

Resistor 0.5W 2.2K ohm Specifications

• Resistance: 2.2 kΩ (2,200 ohms)
• Power rating: 0.5 W (1/2 W)
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 2.2K ohm Applications

• I2C bus pull-ups (SDA and SCL) for sensors and displays
• Base resistors for NPN transistors such as the 2N2222 or BC547
• Current limiting for indicator LEDs on 9 V and 12 V supplies
• Voltage dividers and level shifting
• Electronics education and prototyping

What's in the Box

• 5 × 2.2 kΩ 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 2.2 kΩ the 0.5 W limit is only reached at about 33 V across the resistor, so it is very safe for 3.3 V, 5 V and 12 V circuits.
