SMD Resistor Code Chart Explained – Decode 3-Digit Markings into Ohms, kΩ, and MΩ Values Easily
---
📝 Detailed Information:
This image presents a clear and practical SMD (Surface-Mount Device) resistor code chart, commonly used in modern electronics. These tiny resistors don’t display full resistance values—instead, they use a 3-digit numerical code to represent resistance.
🔍 How the Code Works:
The first two digits represent the significant numbers.
The third digit indicates the number of zeros (multiplier).
📊 Examples from the Chart:
101 → 10 × 10¹ = 100 Ω
102 → 10 × 10² = 1.0 kΩ
152 → 15 × 10² = 1.5 kΩ
222 → 22 × 10² = 2.2 kΩ
332 → 33 × 10² = 3.3 kΩ
472 → 47 × 10² = 4.7 kΩ
103 → 10 × 10³ = 10 kΩ
223 → 22 × 10³ = 22 kΩ
104 → 10 × 10⁴ = 100 kΩ
105 → 10 × 10⁵ = 1.0 MΩ
⚙️ Why This Chart is Useful:
Helps technicians quickly identify resistor values
Essential for PCB repair, DIY electronics, and circuit design
Saves time when working with unlabeled or tiny components
Widely used in mobile repair, TV repair, and embedded systems
