LTCA10.7MS3
Ceramic Filter Series
1. Features and Applications
The LTCA10.7MS3 filters are small,high performance and very thin(1.5mm) chip
devides consisting of 2 ceramic elements for communication equipment.They
are designed on MgTiO
3
ceramic cap package.The filers exhibit flat GDT
characteristic in pass band.The filters are recommended for digital
communication applications and are perfect in hand held cellular phines,pocket
cordless phones, etc.
2. Appearances and Dimendions
Appdarances: smooth surface and clear mark. No visible damage and dirt.
Dimensions: According to Figure 1.
