Resistor 0.5W 330 ohm (5 pcs)

The Resistor 0.5W 330 ohm is a through-hole fixed resistor with a resistance of 330 Ω and a power rating of 0.5 W, sold in a pack of 5. 330 Ω is a popular value for running LEDs at a lower, gentler current from 5 V Arduino pins and for series resistors that protect microcontroller inputs and outputs.

Resistor 0.5W 330 ohm Specifications

• Resistance: 330 Ω
• 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 330 ohm Applications

• Current limiting for indicator LEDs on 5 V boards
• Segment resistors for 7-segment displays and LED bar graphs
• Series resistors on signal lines to protect microcontroller pins
• Data-line resistors for addressable LED strips
• Electronics education and prototyping

What's in the Box

• 5 × 330 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With a red LED (about 2 V) on a 5 V pin, 330 Ω gives roughly 9 mA, bright enough for most indicators. The 0.5 W limit is reached at about 12.8 V across the resistor.
