Resistor 0.5W 620 ohm (5 pcs)

The Resistor 0.5W 620 ohm is a through-hole fixed resistor with a resistance of 620 Ω and a power rating of 0.5 W, sold in a pack of 5. The 620 Ω value sits between 560 Ω and 680 Ω in the E24 series and is useful for setting LED current, biasing transistors and fine-tuning voltage dividers in Arduino and ESP32 projects.

Resistor 0.5W 620 ohm Specifications

• Resistance: 620 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 620 ohm Applications

• Current limiting for LEDs on 5 V and 12 V supplies
• Base resistors for small transistors
• Voltage dividers and pull-down resistors
• Electronics education and prototyping

What's in the Box

• 5 × 620 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With a red LED (about 2 V) on a 12 V supply, a 620 Ω resistor gives roughly 16 mA, a safe current for most 5 mm LEDs. The 0.5 W limit is reached at about 17.6 V across the resistor (P = V² / R).
