Resistor 0.5W 24 ohm (5 pcs)

The Resistor 0.5W 24 ohm is a low-value through-hole fixed resistor with a resistance of 24 Ω and a power rating of 0.5 W, sold in a pack of 5. Low values like this let higher currents flow, so they are used to drive infrared and high-current LEDs, set constant-current sources and act as small test loads in low-voltage circuits.

Resistor 0.5W 24 ohm Specifications

• Resistance: 24 Ω
• Power rating: 0.5 W (1/2 W)
• Type: fixed resistor, axial leads, through-hole
• Maximum current: about 144 mA at the 0.5 W rating
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 24 ohm Applications

• Current limiting for infrared LEDs in remote-control transmitters
• Setting an LM317 constant-current source to about 52 mA (1.25 V / 24 Ω)
• Gate resistors for power MOSFETs
• Small test loads for low-voltage supplies
• Electronics education and prototyping

What's in the Box

• 5 × 24 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 24 Ω the 0.5 W limit is reached at only about 3.5 V across the resistor, so do not connect it directly across a 5 V supply (that would be about 1 W).
