Resistor 0.5W 82 ohm (5 pcs)

The Resistor 0.5W 82 ohm is a through-hole fixed resistor with a resistance of 82 Ω and a power rating of 0.5 W, sold in a pack of 5. Low values like 82 Ω are used to set LED current from 3.3 V microcontroller pins, as gate resistors for MOSFETs and wherever a small series resistance is needed to limit current in low-voltage circuits.

Resistor 0.5W 82 ohm Specifications

• Resistance: 82 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 82 ohm Applications

• Current limiting for red, yellow and green LEDs on 3.3 V (about 16 mA)
• Two red LEDs in series on 5 V (about 12 mA)
• Gate resistors for MOSFETs driven from microcontroller pins
• Series resistors for signal lines and small loads
• Electronics education and prototyping

What's in the Box

• 5 × 82 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 82 Ω, the 0.5 W limit is reached at about 6.4 V across the resistor (P = V² / R), so it is best kept to 3.3 V and 5 V circuits unless you check the power first.
