1. Integrated circuit (Straight Insert /Through Hole)
   Use DIP-pin count + suffix to indicate dual straight Insert package
   There are two types of tails, N and W, which are used to indicate the body width of the device.
   N is a narrow body package with a body width of 300mil and a pin pitch of 2.54mm
   W is the body width package, body width 600mil, pin pitch 2.54mm
   For example: DIP-16N represents a 16-pin narrow body dual straight Insert package with a body width of 300mil and a pin pitch of 2.54mm

2. Integrated circuit (SMD)
   Use SO-pin count + suffix to indicate small outline chip package
   There are three types of tails: N, M and W, which are used to indicate the body width of the device.
   N is a narrow body package with a body width of 150mil and a pin pitch of 1.27mm
   M is a package between N and W, with a body width of 208mil and a pin pitch of 1.27mm
   W is the body width package, body width 300mil, pin pitch 1.27mm
   For example: SO-16N represents a 16-pin small outline chip package with a body width of 150mil and a pin pitch of 1.27mm
   If the SO is preceded by M, it means a micro package with a body width of 118mil and a pin spacing of 0.65mm

3. Resistance
   3.1 The naming method of SMD chip resistor is: package + R
   For example: 1812R means a resistor package with a package size of 1812
   3.2 The naming method of carbon film resistors is: R-package
   For example: R-AXIAL0.6 means a resistor package with a pad spacing of 0.6 inches
   3.3 The naming method of cement resistance is: R-type
   For example: R-SQP5W means cement resistor package with power of 5W

4. Capacitor
   4.1 The naming method of non-polar capacitors and tantalum capacitors is: package + C
   Such as: 6032C means that the package is 6032 capacitor package
   4.2 The naming method of SMT monolithic capacitors is: RAD+pin spacing
   For example: RAD0.2 represents the SMT monolithic capacitor package with a pin pitch of 200mil
   4.3 The naming method of electrolytic capacitors is: RB+pin spacing/outer diameter
   For example: RB.2/.4 means the electrolytic capacitor package with pin spacing of 200mil and outer diameter of 400mil

5. Diode rectifier device
   The naming method is based on the actual package of the components, of which BAT54 and 1N4148 are packaged as 1N4148

6. Transistor
   The naming method is based on the actual package of the component, among which the SOT-23Q package is added with Q to distinguish the SOT-23 package of the integrated circuit, and the other FETs use the component name as the package name in order to call the component without error.

7. Crystal oscillator
   HC-49S, HC-49U are surface mount packages, AT26, AT38 are cylindrical packages, digital meter specifications and dimensions
   For example: AT26 represents a cylindrical package with an outer diameter of 2mm and a length of 8mm

8. Inductors and transformers
   The inductor package is packaged by TDK company

9. Photoelectric devices
   9.1 The naming method of SMD light-emitting diode is package + D to indicate
   Such as: 0805D means the light-emitting diode packaged as 0805
   9.2 In-line light-emitting diodes are expressed as LED-outer diameter
   For example, LED-5 means an in-line light-emitting diode with an outer diameter of 5mm 9.3 The digital tube is named with the device’s own name

10. Plug

10.1 SIP + pin number + pin spacing to represent a single row of pins, the pin spacing is two types: 2mm, 2.54mm
For example: SIP7-2.54 means a 7-pin single-row pin with a pin pitch of 2.54mm
10.2 DIP + pin number + pin spacing to represent double row pins, the pin spacing is two types: 2mm, 2.54mm
For example: DIP10-2.54 means 10-pin double-row pins with a pin pitch of 2.54mm
