Hello all,
I've been buying parts to complete my AudioSector LM4780 boards but the BOM info online is a little lacking. I have all the parts soldered up (including 0.5W resistors instead of the 0.25W resistors that would actually fit on the board) except for Cz. I see it's a 0.1uF capacitor, but what voltage rating is required for this? I can't find the info anywhere, it's not even listed as included in the kit from AudioSector
Thanks!

Cz is the Zobel network Capacitor. According to the LM4780 Data sheet it should be 20% Monolithic Ceramic. The datasheet doesn't give a voltage rating but these mostly have a 50v rating. As it is only subjected to audio levels, this should be adequate. However looking at other kits for this amplifier, I notice they use 63v rated capacitors.
Excellent answer, thank you. I didn't think to look in the datasheet for this as I figured it was something that Peter specced, but there you go. I'll get something over 50v just to be safe
