Hi everyone. We are trying to identify the following component. It is key to understand the functionality of a device we are analyzing. Does anyone have an idea what is the function of this component? Thanks in advance

 

Wow, another mind reading thread with only a picture and no other information.

A total WAG

Hi Nsaspook! Thanks for the reply and the links!

Unfortunately we cannot offer more information because we are at the very beginning of the analysis. We want to have first an idea of which kind of component we are dealing with to figure out which should be the next step. The component is part of a humidity sensor board that we are analyzing

One possibility is a Ricoh R3111N581B Low Voltage Detector.
