Resistor 0.25W 2.2K ohm (10 pcs)

The Resistor 0.25W 2.2K ohm is a through-hole fixed resistor with a resistance of 2.2 kΩ and a power rating of 0.25 W (1/4 W), sold in a pack of 10. 2.2 kΩ is a popular standard value for I2C pull-up resistors, transistor base resistors and low-current LED indicators in Arduino, ESP32 and Raspberry Pi projects.

Resistor 0.25W 2.2K ohm Applications

• Pull-up resistors on I2C SDA and SCL lines
• Base resistors for NPN transistors driving relays and buzzers
• Low-current LED indicators
• Voltage dividers and level shifting
• Electronics education and prototyping

What's in the Box

• 10 × 2.2 kΩ 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. On a 5 V supply, a 2.2 kΩ resistor in series with a red LED gives about 1.4 mA, enough for a soft indicator light; use 220–330 Ω if you need full brightness.
