Found this circuit board from an 1980s old humidity controlled chamber. This definitely looks like a temperature regulator of some sort. It has a M logo which means made by Motorola. It has the labels E03G-3-9 and 8739. Does anyone have any info on what this part is?
Thanks in advance.
I plan to design a series RLC discharge circuit as shown:
Taking into account component parasitics, the actual circuit resembles the following:
'R' = capacitor ESR + load resistance + inductor ESR,
'L' = capacitor ESL + load inductance ≈ load inductance
According to online...
