Resistor 0.5W 150 Ohm (5 pcs)

The Resistor 0.5W 150 Ohm is a through-hole fixed resistor with a resistance of 150 Ω and a power rating of 0.5 W, sold in a pack of 5. At 5 V it sets about 20 mA through a standard red, yellow or green LED, so it is a good current-limiting resistor for bright indicator LEDs and 7-segment displays in Arduino projects.

Resistor 0.5W 150 Ohm Specifications

• Resistance: 150 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 150 Ohm Applications

• Current limiting for LEDs on 5 V supplies
• Segment resistors for 7-segment displays
• Series resistors for driving small loads from microcontroller pins
• Base resistors for transistors that switch larger currents
• Electronics education and prototyping

What's in the Box

• 5 × 150 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 150 Ω, the 0.5 W limit is reached at about 8.7 V across the resistor, so do not connect it directly across a 12 V supply; 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.
