What is the Symbol for the SJC27145A Remote Control Circuit?

AI Thread Summary
The SJC27145A remote control circuit features a crystal component that sets frequency based on its natural vibration, identified by "TX1" on the board. An inductor labeled "L2" is also present on the circuit, which may relate to previous inquiries. The discussion centers on identifying the symbols associated with these components. Understanding these symbols is crucial for circuit analysis and troubleshooting. The thread emphasizes the importance of recognizing these elements in remote control technology.

This one is a crystal. It's used for setting a frequency from its natural vibration.
 


Yes - it says "TX1" on the board. I think you will spot "L2" (i.e. an inductor) on the component at the back of the picture - is that the one you asked about in a previous post?
 


This is remote control circuit an the series is SJC27145A What is the symbol?

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
