Resistor 0.5W 1K ohm (5 pcs)

The Resistor 0.5W 1K ohm is a through-hole fixed resistor with a resistance of 1 kΩ and a power rating of 0.5 W, sold in a pack of 5. It is a go-to value for limiting LED current, driving transistor bases from microcontroller pins and building simple voltage dividers in Arduino and ESP32 projects.

Resistor 0.5W 1K ohm Specifications

• Resistance: 1 kΩ (1,000 ohms)
• 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 1K ohm Applications

• Current limiting for indicator LEDs
• Base resistors for NPN transistors such as the 2N2222 or BC547
• Voltage dividers and level shifting
• Protecting microcontroller pins in test circuits
• Electronics education and prototyping

What's in the Box

• 5 × 1 kΩ 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 1 kΩ, the 0.5 W limit is reached at about 22 V across the resistor, so check the power (P = V² / R) when using it at higher voltages.

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