103
Supports 3/4 digit standard & EIA-96
Calculated Resistance
10 kΩ
Standard 3-digit Code
Quick Guide
- • 103 = 10 × 10³ = 10 kΩ
- • 4702 = 470 × 10² = 47 kΩ
- • 4R7 = 4.7 Ω (R is decimal)
- • 01C (EIA-96) = Code 01 (100) × Mult C (100) = 10 kΩ

P = V × I
Resistor Types
Carbon Film (THT)
Most common through-hole type. Beige body. Cheap, general purpose, 5% tolerance typical.
Metal Film (THT)
Blue body usually. Higher precision (1%), lower noise than carbon. Good for audio/instruments.
SMD (Chip)
Surface Mount Device. Tiny rectangular blocks. Used in modern electronics to save space. Codes printed on top.
