I'm using this DPDT relay - http://pewa.panasonic.com/pcsd/p...
The datasheet states that the coil is polarized, but the schematic shows a simple coil.
I'm guessing that the coil is polarized by the addition of a diode across the coil, but nowhere does it state this. In my current design I have external diodes in parallel with the coils of the relays. I'm getting ready to order more boards and I'm trying to clean the board up a bit, without degrading the performance of the circuit. All of the boards will be hand soldered so I'm looking for minimal component count. Should the diodes stay or go?
