Resistor 0.5W 51 ohm (5 pcs)

The Resistor 0.5W 51 ohm is a low-value through-hole fixed resistor with a resistance of 51 Ω and a power rating of 0.5 W, sold in a pack of 5. Low values like 51 Ω are used where more current must flow, for example with LEDs on low supply voltages, as gate resistors for MOSFETs, and as a close match to 50 Ω for signal termination.

Resistor 0.5W 51 ohm Specifications

• Resistance: 51 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 51 ohm Applications

• Series resistors for LEDs on low supply voltages
• Gate resistors for MOSFETs driven from a microcontroller or driver
• Approximate 50 Ω termination for signal and RF test work
• Small test loads and current-sense experiments
• Electronics education and prototyping

What's in the Box

• 5 × 51 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. Watch the power with low values: with 51 Ω the 0.5 W limit is reached at only about 5 V across the resistor (about 100 mA), so check P = V² / R before connecting it across a supply.
