Resistor 0.5W 240 ohm (5 pcs)

The Resistor 0.5W 240 ohm is a through-hole fixed resistor with a resistance of 240 Ω and a power rating of 0.5 W, sold in a pack of 5. It is the classic value used between the output and adjust pins of the LM317 voltage regulator, and it also works well for limiting LED current in 5 V Arduino projects.

Resistor 0.5W 240 ohm Specifications

• Resistance: 240 Ω
• Power rating: 0.5 W (1/2 W)
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 240 ohm Applications

• Setting resistor (R1) for LM317 adjustable voltage regulators
• Current limiting for LEDs on 5 V supplies (about 12 mA for a red LED)
• Protecting microcontroller output pins
• Pull-down and load resistors in test circuits
• Electronics education and prototyping

What's in the Box

• 5 × 240 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 240 Ω, the 0.5 W limit is reached at about 11 V across the resistor, so check the power (P = V² / R) before using it on 12 V circuits.
