Surface mount device , SMD, resistors are the most widely used electronic component. They're designed to have small metal tabs that could be directly soldered to the surface of the PCB.It makes your design much smaller and compact than through-hole components. Because it needs fewer holes to be drilled.
This package includes 25 strip of 20 SMD resistors - 0805. It covers commonly used smd resistors.But due to the small sizes and lead spacings of many SMDs, soldering this smd resistors requires skilled operators and more expensive tools for your component-level repair or manual prototype assembly.
