LTCV107MA19
Ceramic Filter
1 SCOPE
This specification shall cover the characteristics of the ceramic
fliter with the
type LTCV10.7MA19. The LTCV10.7MA19 filters are small, high performance and
very thin (1.5mm) chip devices consisting of 2 ceramic elements for communication
equipment. They are designed on MgTiO
3
ceramic cap package.
