Resistor 0.25W 220 ohm (10 pcs)

The Resistor 0.25W 220 ohm is a through-hole fixed resistor with a resistance of 220 Ω and a power rating of 0.25 W (1/4 W), sold in a pack of 10. The 220 Ω value is one of the most popular choices for limiting LED current on Arduino and ESP32 pins, and the quarter-watt size fits neatly on breadboards and in signal circuits.

Resistor 0.25W 220 ohm Specifications

• Resistance: 220 Ω
• Power rating: 0.25 W (1/4 W)
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 10 pieces

Resistor 0.25W 220 ohm Applications

• Current limiting for LEDs on 5 V and 3.3 V microcontroller pins
• Series resistors for 7-segment displays and LED bar graphs
• Protecting microcontroller pins in test circuits
• Voltage dividers and general signal circuits
• Electronics education and prototyping

What's in the Box

• 10 × 220 Ω 0.25 W resistors

Tip: With a red LED (about 2 V) on a 5 V pin, a 220 Ω resistor gives roughly 14 mA, and on a 3.3 V pin about 6 mA. Resistors have no polarity, and with 220 Ω the 0.25 W limit is reached at about 7.4 V across the resistor (P = V² / R).
