Functional Description

C1, C2, C3, C4

Not Installed

Snubber to reduce voltage ringing when the device turns off

Add the capacitors if a long harnesses are used to connect the power source or load to the

board.

C8

Not Installed

Output (Load) Capacitor, this capacitor can be installed if instead of C7 if the user requires a

ceramic load capacitor, 1812 package can accommodate a high ceramic capacitors value at

25V rating.
