The attached circuit shows a 0.1 uF decoupling cap across the relay. Is that common practice? The intended use is with a relatively low current miniature relay with a 33 mA coil at 12V.
I have also seen smaller (e.g., 0.001 uF) caps across the diode, which I assume is for snubbing. Again, how common and necessary is that?
These might be unimportant details. I am just seeking advice from other's experience. Thanks.
