Resistor 0.5W 8.2 ohm (5 pcs)

The Resistor 0.5W 8.2 ohm is a through-hole fixed resistor with a low resistance of 8.2 Ω and a power rating of 0.5 W, sold in a pack of 5. Values this low are used for current sensing, limiting current in LED and charging circuits, and as a small dummy load close to the 8 Ω impedance of many speakers when testing low-power amplifiers.

Resistor 0.5W 8.2 ohm Specifications

• Resistance: 8.2 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 8.2 ohm Applications

• Current sensing with an Arduino analog input (V = I × R)
• Dummy load for testing small audio amplifiers at low power
• Current limiting for infrared and high-current LEDs
• Gate resistors for power MOSFETs
• Series resistors in battery charge and discharge test circuits

What's in the Box

• 5 × 8.2 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 8.2 Ω, the 0.5 W limit is reached at only about 2 V across the resistor (about 250 mA); across 5 V it would dissipate about 3 W and burn, so always calculate P = V² / R first.

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