Resistor 0.5W 1.3 ohm (5 pcs)

The Resistor 0.5W 1.3 ohm is a through-hole fixed resistor with a resistance of 1.3 Ω and a power rating of 0.5 W, sold in a pack of 5. This standard E24 low value keeps the voltage drop small even at a few hundred milliamps, so it suits current measurement and current limiting in low-voltage circuits.

Resistor 0.5W 1.3 ohm Specifications

Resistor 0.5W 1.3 ohm Applications

• Current-sense resistor for measuring load current
• LED driver and LED current limiting circuits
• Series resistors in battery and USB-powered projects
• Replacement resistor for electronic repairs
• Prototyping and test benches

What's in the Box

• 5 × 1.3 Ω 0.5 W resistors

Tip: To work out current, divide the voltage across the resistor by 1.3: 0.13 V means 100 mA. The 0.5 W limit is reached at about 620 mA (about 0.8 V across it), so keep well below that.
