7 Channel LCD Filter Array with ESD Protection
Figure 1 Schematic
Description
BGF108C is a 7 channel RC filter array to provide attenuation of undesired signals in the 800 - 2000 MHz range.
All pins are protected against ESD of 15 kV according to IEC61000-4-2 (contact discharge). The wafer level
package is a green package with a size of only 1.95 mm x 2.07 mm and a total height of 0.60 mm. The package
has been improved for increased drop test reliability.
Feature
• 7 channel integrated RC filter array
• ESD protection according to IEC61000-4-2
of 15 kV contact discharge on all IOs
• Wafer Level Package with SnAgCu solder balls
•400 µm solder ball pitch
• RoHS and WEEE compliant package
• Improved package for increased drop test reliability
