Resistor 0.5W 68 ohm (5 pcs)

The Resistor 0.5W 68 ohm is a through-hole fixed resistor with a resistance of 68 Ω and a power rating of 0.5 W, sold in a pack of 5. It is a useful low value for driving LEDs from 3.3 V boards such as the ESP32, for MOSFET gate resistors and for limiting current to small loads in low-voltage electronics.

Resistor 0.5W 68 ohm Specifications

• Resistance: 68 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 68 ohm Applications

• Current limiting for red, yellow and green LEDs on 3.3 V (about 19 mA)
• Two red LEDs in series on 5 V (about 15 mA)
• Gate resistors for MOSFETs driven from Arduino or ESP32 pins
• Series resistors for signal lines and small loads
• Electronics education and prototyping

What's in the Box

• 5 × 68 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 68 Ω, the 0.5 W limit is reached at about 5.8 V across the resistor (P = V² / R), so check the power before using it with anything above 5 V.
