passive components

Hello! Does anyone know what this white component is, and what its role is in the SIM800L module circuit? Thanks in advance!

Hello friends, I am working on a project where I am only allowed to use analog components. I cannot use ICs, microcontrollers, or microprocessors. I plan to use a passive transducer pair as a motion sensor. The main component I need to use in my circuit is the 555 Timer. I will use the 555 Timer...

Hi, I'm working on a little project and I have a question about capacitor. If 400V AC capacitor would be connected to 400V source, the capacitor could store around 565V DC (400V x √2), if I'm not wrong. So what if there would be over 500V DC source, would capacitor still be able to hold ...

So, I found these models for Line Impedance Stabilization Network (LISN) in two different books. I want to simulate these two models in LTspice, but I don't know which side to connect the EUT and which side to connect the spectrum analyzer and ofcourse, where to connect the source? and how do I...
