Package knowledge of various common electronic components in the circuit board

Resistance: RES1, RES2, RES3, RES4; package attribute is axial series

Non-polarity capacitor: cap; package properties are RAD-0.1 to rad-0.4

Electrolytic capacitor: electroi; package attribute is rb.2/.4 to rb.5/1.0

Resistance: AXIAL0.3-AXIAL0.7 where 0.4-0.7 refers to the length of the resistor, generally using AXIAL0.4

Ceramic Capacitor: RAD0.1-RAD0.3. Among them, 0.1-0.3 refers to the size of the capacitor, generally using RAD0.1

Electrolytic Capacitor: RB.1/.2-RB.4/.8 where .1/.2-.4/.8 refers to the size of the capacitor. Generally <100uF with RB.1/.2, 100uF-470uF with RB.2/.4, >470uF with RB.3/.6
