In a project I use several 12v dc coil electromechanical relays. I use diodes in parallel to the coil protect them from flyback.
I also have one relay with an 240v ac coil. I have learned that I should use an RC snubber in parallel to the coil in stead of a diode (I'm new to electronics). I have researched a lot, but I feel unable to transpose most calculations or answers I found on here or the internet to my project (again, I'm a novice). Can anyone help me calculate which type of RC snubber (or which values) I need for my relay?
These are the numbers from the datasheet (marked in yellow):
Is an RC snubber enough for protection?
