MERITEK Multilayer Ceramic Chip Capacitors supplied in
bulk or tape & reel package are ideally suitable for thick-film
hybrid circuits and automatic surface mounting on any
printed circuit boards, All of MERITEK's MLCC products meet
RoHS directive.
ST series use a special material between nickel-barrier
and ceramic body. It provides excellent performance to
against bending stress occurred during process and
provide more security for PCB process.
The nickel-barrier terminations are consisted of a nickel
barrier layer over the silver metallization and then finished by
electroplated solder layer to ensure the terminations have
good solderability. The nickel barrier layer in terminations
prevents the dissolution of termination when extended
immersion in molten solder at elevated solder temperature.
