Just when we all thought chip components of 0201 (0.6 x 0.3mm) were small, the next wave of miniaturisation is on us.
The smaller a piece of electronic equipment becomes, and the more complex its functions, the more extensive are the integration of its circuits.
This integration of capacitors and other components into chips stimulates and supports progress in the miniaturisation of equipment.
For example between 200 and 300 chip capacitors are used in a single mobile phone.
Practical Components can now supply dummy resistors in the metric 0402 size for process development and planning.
These new components are approximately half the size of a 0201s, measuring a mere 0.4 x 0.2mm.
0402 metric components come standard on paper tape and reels of up to 1000 components.
Reel quantity is based on engineering sample quantities.
These SMD components, along with advances in mounting technology continue to push the development of more compact components with increasingly advanced functions.
