Resistor 0.5W 430 ohm (5 pcs)

The Resistor 0.5W 430 ohm is a through-hole fixed resistor with a resistance of 430 Ω and a power rating of 0.5 W, sold in a pack of 5. It is a good value for limiting LED current on 5 V to 9 V supplies, protecting microcontroller pins and setting current in small transistor circuits.

Resistor 0.5W 430 ohm Specifications

• Resistance: 430 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 430 ohm Applications

• Current limiting for LEDs: about 7 mA for a red LED at 5 V, about 16 mA at 9 V
• Series resistors to protect Arduino and ESP32 pins
• Base and collector resistors in transistor circuits
• Voltage dividers and pull-down resistors
• Electronics education and prototyping

What's in the Box

• 5 × 430 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 430 Ω, the 0.5 W limit is reached at about 14.7 V across the resistor, so check the power (P = V² / R) when using it on 12 V or higher supplies.
