Resistor 0.25W 22 ohm (10 pcs)

The Resistor 0.25W 22 ohm is a 22 Ω through-hole resistor with a 0.25 W (1/4 W) power rating, in a pack of 10. 22 Ω is one of the most common low values: it is the series resistor recommended on the USB data lines of chips such as the ATmega32U4, and it works well as a MOSFET gate resistor or a damping resistor on fast signals.

Resistor 0.25W 22 ohm Applications

• Series resistors on USB D+ and D− lines in microcontroller boards
• Gate resistors between a driver and a power MOSFET
• Series termination to reduce ringing on SPI clock and other fast digital lines
• LM317 constant-current source: 1.25 V / 22 Ω gives about 57 mA
• Electronics education and prototyping

What's in the Box

• 10 × 22 Ω 0.25 W resistors

Tip: Check the third colour band before fitting: 22 Ω is red, red, black, while the more common 220 Ω is red, red, brown. A quick check with a multimeter avoids mixing them up.
