Member: 1062107 Status: Offline Thanks Meter: 544 | How to Identify Component Symbols on Nokia Schematic Diagram? Identifying with Symbols on Schematic Diagram is very easy task, it's just like reading ABC's on English alphabet. Since we are talking about mobile phone's circuit here, we are going to tackle only on its symbols being used herein, unlike in some major electronics components which have a lot of component symbols. Mostly, because Cellphone circuits have a lot of Integrated Circuit ( IC ) meaning the circuits is being compact into a smaller circuit to produce, and save a very small space to put a huge circuit connection into one tiny piece of circuits. I have inserted the Layout of each component and how it's look's like mounted on a PCB ( Printed Circuit Board) for better and easiest way of understanding. Simply Click on Components Category for more Detailed Infos. Resistor |

Zener is always been in a circuit and always play the roll to rectify and stabilized voltage and currents. Newly designed Zeners are SMD (Surface Mounted) so it is not easy to identify them by looks. If you are familiar with Integrated Circuit Datasheets ( chips schematic diagrams) you can see that it is accompanied zeners inside it. | |
