Resistor 0.5W 47 ohm (5 pcs)

The Resistor 0.5W 47 ohm is a through-hole fixed resistor with a low resistance of 47 Ω and a power rating of 0.5 W, sold in a pack of 5. Low values like this are used where more current must flow, such as gate resistors for MOSFETs, current limiting for infrared and high-current LEDs, and small series resistors that damp ringing on signal lines.

Resistor 0.5W 47 ohm Specifications

• Resistance: 47 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 47 ohm Applications

• Gate resistors for MOSFETs driven from Arduino or ESP32 pins
• Current limiting for infrared LEDs and high-current LEDs
• Series resistors on signal lines to reduce ringing and noise
• Backlight resistors for small displays
• Electronics education and prototyping

What's in the Box

• 5 × 47 Ω 0.5 W resistors

Tip: With only 47 Ω, the 0.5 W limit is reached at about 4.8 V across the resistor (around 100 mA), so never connect it directly across a 5 V supply. Always use it in series with a load and check the power with P = V² / R.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
