Resistor 0.25W 1K ohm (10 pcs)

The Resistor 0.25W 1K ohm is a through-hole fixed resistor with a resistance of 1 kΩ and a power rating of 0.25 W (1/4 W), sold in a pack of 10. The quarter-watt size is the standard for breadboard and signal circuits, and 1 kΩ is one of the most used values for limiting LED current, driving transistor bases and building voltage dividers in Arduino and ESP32 projects.

Resistor 0.25W 1K ohm Specifications

• Resistance: 1 kΩ (1,000 ohms)
• Power rating: 0.25 W (1/4 W)
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 10 pieces

Resistor 0.25W 1K ohm Applications

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

What's in the Box

• 10 × 1 kΩ 0.25 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 1 kΩ, the 0.25 W limit is reached at about 15.8 V across the resistor (P = V² / R), so check the power when using it with supplies above about 15 V.

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