Resistor 0.5W 100 ohm (5 pcs)

The Resistor 0.5W 100 ohm is a through-hole fixed resistor with a resistance of 100 Ω and a power rating of 0.5 W, sold in a pack of 5. Low values like 100 Ω are used where only a little current limiting is needed, such as LEDs on low-voltage supplies, MOSFET gate resistors and series protection on signal lines.

Resistor 0.5W 100 ohm Specifications

• Resistance: 100 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 100 ohm Applications

• Current limiting for red and green LEDs on 3.3 V supplies
• Gate resistors for MOSFETs driven from Arduino or ESP32 pins
• Series resistors to protect signal and data lines
• Load and shunt resistors for simple current tests
• Electronics education and prototyping

What's in the Box

• 5 × 100 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 100 Ω the 0.5 W limit is reached at only about 7 V across the resistor (70 mA), so check the power with P = V² / R before using it on 9 V or 12 V supplies.
