Resistor 0.25W 330 ohm (10 pcs)

The Resistor 0.25W 330 ohm is a through-hole fixed resistor with a resistance of 330 Ω and a power rating of 0.25 W (1/4 W), sold in a pack of 10. The 330 Ω value is the classic choice for limiting the current of an LED connected to a 5 V Arduino pin, and the quarter-watt size fits breadboards and signal circuits.

Resistor 0.25W 330 ohm Applications

• Current limiting for LEDs on 5 V Arduino and 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 × 330 Ω 0.25 W resistors

Tip: With a red LED (about 2 V) on a 5 V pin, a 330 Ω resistor gives roughly 9 mA, which is bright and safe. Resistors have no polarity, and with 330 Ω the 0.25 W limit is reached at about 9 V across the resistor (P = V² / R), so check the power at higher voltages.
