Resistor 0.5W 200 ohm (5 pcs)

The Resistor 0.5W 200 ohm is a through-hole fixed resistor with a resistance of 200 Ω and a power rating of 0.5 W, sold in a pack of 5. It is a handy value for limiting LED current at 3.3 V and 5 V, protecting microcontroller pins and setting the current in small transistor and optocoupler circuits in Arduino and ESP32 projects.

Resistor 0.5W 200 ohm Specifications

• Resistance: 200 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 200 ohm Applications

• Current limiting for LEDs: about 15 mA for a red LED at 5 V
• Series resistors to protect microcontroller pins
• Gate resistors for MOSFETs and base resistors for power transistors
• Input resistors for optocouplers such as the PC817
• Electronics education and prototyping

What's in the Box

• 5 × 200 Ω 0.5 W resistors

Tip: Resistors have no polarity, so they can be fitted either way round. With 200 Ω, the 0.5 W limit is reached at 10 V across the resistor (50 mA), so check the power (P = V² / R) when using it at higher voltages.

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