Resistor 0.5W 12 ohm (5 pcs)

The Resistor 0.5W 12 ohm is a through-hole fixed resistor with a low resistance of 12 Ω and a power rating of 0.5 W, sold in a pack of 5. 12 Ω is a standard E12 value used for setting current, limiting current and adding a small series resistance in low-voltage power, LED and audio circuits.

Resistor 0.5W 12 ohm Specifications

• Resistance: 12 Ω
• Power rating: 0.5 W (1/2 W)
• Maximum current: about 200 mA at the full 0.5 W rating
• Colour code: brown, red, black (4-band) or brown, red, black, gold (5-band), plus a tolerance band
• Type: fixed resistor, axial leads, through-hole
• Pack size: 5 pieces

Resistor 0.5W 12 ohm Applications

• LM317 constant-current source for LEDs: 1.25 V / 12 Ω ≈ 104 mA
• Current limiting for small lamps and low-voltage loads
• Series protection resistors for small speakers and buzzers
• Gate and damping resistors in switching circuits
• Electronics education and repair work

What's in the Box

• 5 × 12 Ω 0.5 W resistors

Tip: Resistors have no polarity. In the LM317 example the resistor dissipates about 0.13 W (1.25 V × 104 mA), comfortably within its 0.5 W rating; never place it straight across a supply above about 2.4 V.
