- Difference between 1206, 0805 and 0603 SMD resistor
The codes you are referring to are size codes, e g 1206 means 0 125x0 060 inches There are some other differences, except for size Smaller resistors probably feature a lower power and voltage rating, but can have smaller parasitic components, ESL and parallel capacitance

- SMD size 0805 vs 1206 - Electrical Engineering Stack Exchange
I think (based on prices and availability) 0603 is a better choice for the future, and use 0805 1206 or bigger where necessary 0603 is pretty easy to solder by hand and any assembly house can handle it with high yield 0402 is a bit cheaper for bypass capacitors in typical sizes if you don't mind the 10K per reel granularity of buying by the reel
- pcb - Hand soldering SMD 1206 components - Electrical Engineering Stack . . .
1206 (Imperial, 3216 metric) is very easy to solder by hand It's very big in the SMD world With an normal, 0 5-1mm chisel, iron you can go down to 0603 (imperial, 1608 metric), then hot-air becomes a requirement to do it with reasonable quality
- Luminous flux of 0603 and 1206 LEDs with the same color and current . . .
A manufacturer may offer a chipled in 0603, 0805 and 1206 packages The actual chip is the same, but the optics are different Peak light output (luminous intensity) may vary but the total light output (luminous flux) is about the same You should be able to see this if you look at the beam shape You'll most likely also see a difference in

- surface mount - SMT Resistor array package type - Electrical . . .
1206 is a common large SMT resistor package, as you guessed It refers to a 120 mil by 60 mil rectangular package Some newcomers to SMT prefer to use individual 1206 components, but most use 0805 (80 by 50 mils you get the idea) for general resistors that have to be hand soldered
- SMD resistor maximum voltage: is 200V really a limiting factor?
2) When you just have high voltage drops (large resistor values) Use a series network with resistors (for ex: 1206 1 4W) 3-4 1206 resistors in series for 230VAC and 4-5 for 400VAC are good numbers Again the resistor network voltage drop is higher than the calculated Also here you can use a wider range of resistor technologies Metal film
