Resistor 0.5W 33 ohm (5 pcs)

The Resistor 0.5W 33 ohm is a through-hole fixed resistor with a low resistance of 33 Ω and a power rating of 0.5 W, sold in a pack of 5. Low values like this are used where a little resistance is needed in series with a load or signal, such as limiting current to power LEDs, damping fast signal lines or adding a gate resistor to a MOSFET.

Resistor 0.5W 33 ohm Specifications

• Resistance: 33 Ω
• Power rating: 0.5 W (1/2 W)
• Maximum current at full rating: about 123 mA (I = √(P ÷ R))
• Type: fixed resistor, axial leads, through-hole
• Fits: breadboards, perfboards and PCBs
• Pack size: 5 pieces

Resistor 0.5W 33 ohm Applications

• Current limiting for power LEDs and LED strings
• Gate resistors for MOSFETs driven from Arduino or ESP32 pins
• Series damping resistors on fast digital and clock lines
• Small loads and current-sense experiments
• Electronics education and prototyping

What's in the Box

• 5 × 33 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With only 33 Ω, the 0.5 W limit is reached at about 4 V across the resistor, so never connect it directly across a 5 V supply: it would dissipate about 0.76 W and overheat.

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