SMD component package instructions
LEDs: red, yellow , green, blue points, the brightness of ordinary light, bright , bright three , etc.
Level , there are three common forms of packaging : 0805,1206,1210
Diodes : According to the current exposure limits , package roughly divided into two categories , low current type ( eg 1N4148) package of 1206 , a large current type ( such as IN4007) No no specific package , only to give a specific ruler
Size : 5.5 X 3 X 0.5
Capacitance: can be divided into two types of polar and non-polar , non-polar capacitor of the following two types of packaging is most common, namely 0805, 0603 ; while polar capacitor is what we usually call the electrolytic capacitors, typically we usually use Up for aluminum electrolytic capacitors , because of its electrolyte aluminum, so its temperature stability and accuracy is not high , but because of its close circuit chip components version , it requires higher temperature stability , so tantalum chip capacitors capacitance as much, depending on its pressure, chip capacitors can be divided into A, B, C, D four series , specifically as follows:
Type of package pressure
A 3216 10V
B 3528 16V
C 6032 25V
D 7343 35V
DIP switch, crystal : and so the market can be found in different specifications SMD package, the price will be based on their performance pin plating , nominal frequency and Dan are associated .
Resistance: The Promise of capacitors and similar , the most common are 0805,0603 two categories, the difference is that she can appear as exclusion , four , eight have a specific style can refer MD16 simulation package version , you can also to the internal PCB design database queries .
Note:
A \ B \ C \ D four types of packages by its specific dimensions , dimensioning of LXSXH
1210 specific size and type of electrolytic capacitors same class B 3528
0805 specific dimensions : 2.0 X 1.25 X 0.5
1206 specific dimensions : 3.0 X 1.5 0X 0.5
