🎛️ 1. COMPONENT DECODERS
════════════════════════════════════════
• 4, 5 and 6 Band Resistor Color Codes:
- Bi-Directional: Select color bands to find resistance OR type an Ohm value (e.g. 4.7k) to visualize band colors automatically.
- Tolerance (%) and temperature coefficient (PPM/K) calculation.
- Automatic nearest standard E12 and E24 value matching.
• SMD Resistor Decoder:
- 3-Digit EIA codes (e.g., 103 ➔ 10 kΩ)
- 4-Digit precision codes (e.g., 4702 ➔ 47 kΩ)
- EIA-96 high precision standard (e.g., 01C ➔ 10 kΩ ±1%)
- Decimal "R" markings (e.g., 4R7 ➔ 4.7 Ω) and zero-ohm jumpers.
• Capacitor Code Converter:
- Converts 3-digit ceramic and film capacitor codes into pF, nF, and µF.
- Includes tolerance letter codes (J: ±5%, K: ±10%, M: ±20%) and voltage ratings (1H: 50V, 2A: 100V).
• Inductor Color Codes:
- 4-band axial inductor inductance (µH) and tolerance.
