FlexiCap Virtually Eliminates Multilayer Chip Capacitor Cracking!
Multilayer ceramic chip capacitors are renowned for their reliability but can be vulnerable to cracks when affected by PCB flexing. The resulting damage may not manifest itself immediately, but may ultimately result in field failure. Syfer Technology and Novacap have introduced a polymer termination to their range of Multilayer Chip Capacitors to permit greater degrees of board bending without damage to capacitors.
