Resistor 0.5W 1.8 ohm (5 pcs)

The Resistor 0.5W 1.8 ohm is a low-ohm through-hole fixed resistor with a resistance of 1.8 Ω and a power rating of 0.5 W, sold in a pack of 5. It is used where current is high and the voltage drop must stay small, for example in current-sense circuits, LED drivers and battery-powered projects.

Resistor 0.5W 1.8 ohm Specifications

Resistor 0.5W 1.8 ohm Applications

• Current sensing in battery chargers and power monitors
• Series resistors for power LEDs
• Current limiting in low-voltage power lines
• Repair of power supplies and audio boards
• Electronics prototyping

What's in the Box

• 5 × 1.8 Ω 0.5 W resistors

Tip: Resistors have no polarity. With 1.8 Ω, 100 mA gives a 0.18 V drop and 0.018 W of heat; the 0.5 W limit is reached at about 527 mA, so check P = I² × R before using it on larger loads.
