FAQ  

1. What does the “120” marking mean on this 1206 resistor?
   “120” is the standard 3-digit code for 12 Ohms (12 × 10⁰ = 12Ω).
2. Can this resistor handle more than 1/4 watt?
   No — maximum continuous power is 0.25W. Exceeding this can cause overheating or failure.
3. Why choose 1% tolerance instead of 5%?
   1% offers much tighter accuracy (±0.12Ω variation max), critical for precision analog circuits.
4. Is hand soldering possible with 1206 size?
   Yes, 1206 is one of the easier SMD sizes for hand soldering with fine-tip iron and good flux.
5. What are the exact dimensions of a 1206 package?
   Approximately 3.2 mm long × 1.6 mm wide × 0.55 mm high.
6. Is this resistor lead-free and RoHS compliant?
   Yes, standard modern 1206 resistors are RoHS compliant and lead-free.
7. What temperature range can it safely operate in?
   Typically reliable from -55°C to +155°C.
8. Suitable for automotive or outdoor use?
   Yes, as long as voltage, power, and temperature stay within specifications.
9. How is the resistance value printed on low-ohm 1206 resistors?
   Usually a 3-digit code like “120” for 12Ω or “12R0” for some manufacturers.
10. Are these supplied in reels for pick-and-place machines?
    Yes, industry standard is 5,000 pieces per reel for automated assembly.
