What is the LED package number in the Protel 99SE?

Direct-insert LEDs can be packaged with electrolytic capacitors or SMD LEDs, and SMD LEDs can be packaged with chip capacitors of the corresponding size.

It's not difficult to make a package yourself.

1.Standard Resistors: Package: to the crystal schematic

Two-Port Variable Resistor: Package: To.

Three-Port Variable Resistor: Package: VR1-VR5

2.Capacitance: Encapsulation: Non-polarized capacitance is to, polarized capacitance is to.

3.Diode: Package: and diode; (As mentioned above, don't forget to change the port of the DIOD package to A and K when making PCB).

4.Transistors: Pin Package:

Packages above TO18, TO92A, TO220H (high-power triode), and TO3 (high-power Darlington transistor) have a triangular structure. T0-226 is straight, etc.), we commonly use, so the general transistor uses To-126!

5. Effect transistor: The pin package form is the same as that of the transistor.

6. Inductor: , inductor1 package: 1005(2).

8.The commonly used names in the schematic diagram of the rectifier bridge are Bridge1 and Bridge2, and the pin package form is D series, such as D-44, D-37, D-46, etc.

9.The commonly used name in the schematic diagram of a single-row multi-pin socket is the CON series, and the package: SIP series.

10.Dual in-line components Pin Package: DIP, DIP, Series For example, the 40-pin MCU package is DIP40.

11.The commonly used name in the schematic diagram of the serial-parallel port class is DB series, and the pin package form is DB and MD series.

12. Crystal oscillator: crystal; Package: xtal1

13. Light-emitting diode: LED; The package can be only the capacitor package. （

14. a light-emitting digital tube: dpy; As for packaging, it is recommended to do it yourself! （dip8）

15. Toggle switch: SW DIP; Packaging needs to be done by measuring the pin distance by yourself! (sip3)

16. Key switch: SW-PB: The package is the same as above, and you also need to do it yourself. (dip4)

1. The footprint of the Protel99SE light-emitting diode is LED.

2. Light-emitting diodes are referred to as LEDs. It is made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc.

When electrons recombine with holes, they emit visible light, which can be used to make light-emitting diodes. It can be used as an indicator light in circuits and instruments, or as a text or digital display. Gallium arsenide diodes glow red, gallium phosphide diodes glow green, silicon carbide diodes glow yellow, and gallium nitride diodes glow blue.

Due to its chemical properties, it is divided into organic light-emitting diode (OLED) and inorganic light-emitting diode (LED).

You can make unified changes using the global modification function.

For example, the footprint of the resistor in the schematic is changed from all.

Double-click any resistor component, click [Global] in the pop-up Part Properties dialog box, enter the condition A* after Footprint in the pop-up Global Modification dialog box, enter 4=2 in the following dialog box, click [OK], and select [Yes] in the pop-up dialog box. a* here refers to all strings with wrappers that start with a, and 4=2 denotes that all 4 of these wrappers are replaced with 2.
