Protel99SE 封装基础知识(国外英文资料) The resistance of AXIAL Non polar capacitor RAD Electrolytic capacitor RB- Potentiometer VR Diode DIODE Triode TO Power supply block 78 and 79 series TO126H and TO-126V Field effect transistor and transistor. D44 D37 D46 rectifier bridge Single row multi pin socket CON SIP*n Dip component DIP DIP*n Crystal XTAL1 RES1, RES2, resistance: RES3, RES4; package properties for the axial series Non polar capacitor: cap; package properties for the RAD-0.1 to rad-0.4 Electrolytic capacitor: electroi; package properties for the rb.2.4 to rb.51.0 Potentiometer: Pot1, pot2; package properties for the VR-1 to vr-5 Diode: package properties for the diode-0.4 (low power) diode-0.7 (high power) Transistor: package properties common for TO-18 (ordinary transistor) to-22 (power transistor) TO-3 (high power Darlington) Power supply block has 78 and 79 series; 78 series such as 780578127820 79 series of 790579127920. The encapsulation property of common to126h and to126v Bridge: BRIDGE1, BRIDGE2 series of package properties for the D (D-44, D-37, D-46) Resistance: AXIAL0.3-AXIAL0.7 where 0.4-0.7 refers to the resistance length, AXIAL0.4 general use Ceramic capacitors: RAD0.1-RAD0.3. The 0.1-0.3 capacitor size, RAD0.1 for general use Electrolytic capacitor: RB.1.2-RB.4.8 where.1.2-.4.8 refers to the capacitor size. General 100uF RB.1.2100uF-470uF RB.2.4470uF RB.3.6 DIODE0.4-DIODE0.7 0.4-0.7 refers to the diode: diode length, DIODE0.4 for general use Led: RB.1.2 Integrated block: DIP8-DIP40, 8 - 40 how many feet, 8 feet is DIP8 chip resistor 0603 the Never mind package size and specific resistance, but related, package size and power generally 0201 120W 0402 116W 0603 110W 0805 18W 1206 14W The corresponding relationship between capacitance and resistance to the appearance and the size of package is 0402=1.0x0.5 0603=1.6x0.8 0805=2.0x1.2 1206=3.2x1.6 1210=3.2x2.5 1812=4.5x3.2 2225=5.6x6.5 A component package, as we said earlier, in addition to DEVICE.
