What size is 0603 in mm?

Imperial 0603 is approximately 1.6 mm × 0.8 mm. Metric 0603 is a different naming system and is approximately 0.6 mm × 0.3 mm, so always check whether the package code is imperial or metric.

What is the difference between 0805 and 1206 SMD packages?

0805 is approximately 2.0 mm × 1.25 mm, while 1206 is approximately 3.2 mm × 1.6 mm. 1206 is larger, easier to hand solder and usually supports higher power or capacitance options.

Which SMD package is easiest to solder by hand?

0805 and 1206 are usually comfortable for hand soldering. 0603 is possible with practice, while 0402 and smaller packages are much harder without magnification and fine tools.

📚 Design Notes

Footprint is not only body size PCB land pattern includes pads, solder fillets and assembly tolerance. Do not draw pads using only component body dimensions.

0805 and 1206 are beginner-friendly These sizes are easier for hand soldering, debugging and rework. They are good for educational PCBs and prototypes.

0402 and smaller need care Small packages save board area but need better stencil, placement, microscope and soldering process control.

Power rating varies Resistor wattage depends on package, manufacturer, PCB copper area and ambient temperature. Use datasheets for final design.

SMD Package Size Chart

This SMD package size chart helps electronics makers compare common surface-mount component footprints such as 0402, 0603, 0805, 1206, 1210, 2010 and 2512. It is useful when selecting resistor, capacitor, LED and diode package sizes for PCB design.

Imperial vs metric SMD package codes

SMD packages are often named using imperial dimensions, but metric names are also used. This is why a package code can be confusing. For example, imperial 0603 is commonly listed as metric 1608 because it is about 1.6 mm by 0.8 mm.

❓ Frequently Asked Questions

Imperial 0603 is approximately 1.6 mm × 0.8 mm. It is also called metric 1608.

Imperial 0805 is approximately 2.0 mm × 1.25 mm. It is also called metric 2012.

Imperial 1206 is approximately 3.2 mm × 1.6 mm. It is popular for hand soldering and higher-power resistor use.

Yes. Imperial 0402 is about 1.0 mm × 0.5 mm, while imperial 0603 is about 1.6 mm × 0.8 mm.

0805 and 1206 are usually easiest for hand soldering. 0603 is manageable with practice. 0402 and smaller need fine tools and magnification.

The package size codes can be the same, but height, land pattern, tolerance and electrical ratings vary by component type and manufacturer.

Not on the same PCB footprint. 0805 is physically larger and needs a different land pattern unless the PCB footprint was designed to accept both.

Usually yes for resistors, but the exact rating depends on manufacturer, package construction, PCB copper area and temperature derating.
