Insertion/Retention Forces Tests performed on 4 and 5 pin press-fit decks show a consistent insertion force of 100 N per pin.
- 4 pin press-fit deck requires 400 N insertion force
- 5 pin press-fit deck requires 500 N insertion force A force > 500 N has been repeatedly applied to the finished product (4 pin version). Press-Fit Male/Female Interconnects Press-Fit Aluminum Electrolytic Capacitors ALF20 & ALF40 SA1017 Copyright © 2017 KEMET
