Resistor 0.5W 510 ohm (5 pcs)

The Resistor 0.5W 510 ohm is a through-hole fixed resistor with a resistance of 510 Ω and a power rating of 0.5 W, sold in a pack of 5. 510 Ω is a standard E24 value, often used to limit LED current at 5 V, to drive transistor bases harder than a 1 kΩ resistor would, and as a load or termination resistor in signal circuits.

Resistor 0.5W 510 ohm Specifications

• Resistance: 510 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 510 ohm Applications

• Current limiting for LEDs on 5 V, about 6 mA for a red LED
• Base resistors for medium-current transistor switches
• Voltage dividers and load resistors
• Current limiting on microcontroller outputs
• Electronics education and prototyping

What's in the Box

• 5 × 510 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 510 Ω, the 0.5 W limit is reached at about 16 V or 31 mA, so check the power (P = V² / R) when using it on 12 V or 24 V supplies.
