Resistor 0.5W 43 ohm (5 pcs)

The Resistor 0.5W 43 ohm is a through-hole fixed resistor with a low resistance of 43 Ω and a power rating of 0.5 W, sold in a pack of 5. 43 Ω is an E24 series value used where a small series resistance is needed, such as MOSFET gate resistors, current limiting in low-voltage circuits and damping on signal lines.

Resistor 0.5W 43 ohm Applications

• Gate resistors between a microcontroller pin and a power MOSFET
• Current limiting for LEDs and small loads at low voltage
• Series damping resistors on signal lines
• Emitter and collector resistors in small transistor stages
• Electronics education and repair work

What's in the Box

• 5 × 43 Ω 0.5 W resistors

Tip: Do not connect it directly across a 5 V supply: it would dissipate about 0.58 W, above its 0.5 W rating. Keep the voltage across it below about 4.6 V, or use it in series with another load.
