Resistor 0.5W 2 ohm (5 pcs)

The Resistor 0.5W 2 ohm is a low-value through-hole fixed resistor with a resistance of 2 Ω and a power rating of 0.5 W, sold in a pack of 5. Low resistances like this are used where the current is high and only a small voltage drop is wanted, such as current sensing, limiting current to power LEDs and small test loads.

Resistor 0.5W 2 ohm Specifications

Resistor 0.5W 2 ohm Applications

• Current sense resistors for measuring current with an ADC or meter
• Current limiting for high-brightness LEDs
• Small dummy loads for testing
• Series resistors in charging and power circuits
• Electronics education and repairs

What's in the Box

• 5 × 2 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With low values, check the power with P = I² × R: at 0.5 A a 2 Ω resistor already dissipates its full 0.5 W, so keep the current lower to leave a safety margin.
