Resistor 0.5W 2.7 ohm (5 pcs)

The Resistor 0.5W 2.7 ohm is a low-value through-hole fixed resistor with a resistance of 2.7 Ω and a power rating of 0.5 W, sold in a pack of 5. Low values like this are used where a small, controlled voltage drop is needed, such as measuring current, limiting current in low-voltage circuits or adding a little series resistance to a power line.

Resistor 0.5W 2.7 ohm Specifications

• Resistance: 2.7 Ω
• Power rating: 0.5 W (1/2 W)
• Current at full power: about 0.43 A
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 2.7 ohm Applications

• Simple current sensing: measure the voltage across the resistor and divide it by 2.7 Ω
• Current limiting for power LEDs and small loads in low-voltage circuits
• Series resistance in power and battery lines
• Repairing power supply, charger and audio boards that use a 2.7 Ω part
• Electronics education and prototyping

What's in the Box

• 5 × 2.7 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With such a low value the power limit comes quickly: 0.5 W is reached at about 0.43 A (about 1.16 V across the resistor), so check P = I² × R before using it in higher-current circuits.
