Resistor 0.5W 15 ohm (5 pcs)

The Resistor 0.5W 15 ohm is a through-hole fixed resistor with a low resistance of 15 Ω and a power rating of 0.5 W, sold in a pack of 5. Low values like 15 Ω are used to set or measure current with a small voltage drop, for example in constant-current LED drivers, current-sense circuits and series protection in low-voltage power circuits.

Resistor 0.5W 15 ohm Specifications

• Resistance: 15 Ω
• Power rating: 0.5 W (1/2 W)
• Maximum current: about 180 mA at the full 0.5 W rating
• Colour code: brown, green, black (4-band) or brown, green, black, gold (5-band), plus a tolerance band
• Type: fixed resistor, axial leads, through-hole
• Pack size: 5 pieces

Resistor 0.5W 15 ohm Applications

• LM317 constant-current source for LEDs: 1.25 V / 15 Ω ≈ 83 mA
• Current-sense resistors in chargers and test circuits
• Series resistors for small speakers and buzzers
• Gate and damping resistors in switching circuits
• Electronics education and repair work

What's in the Box

• 5 × 15 Ω 0.5 W resistors

Tip: Check the power with P = V² / R: even 3.3 V across 15 Ω gives about 0.73 W, more than this resistor can handle. Keep the voltage across it below about 2.7 V.
