Product Description
The CM1300 is a 4-channel low pass EMI filter (R-C-R
configuration) manufactured in a Chip Scale Package
(CSP). Many portable applications require the attenua-
tion of signals in the 800-3000 MHz band. California
Micro Devices’ unique thin film technology provides a
minimum of –25dB of attenuation over this frequency
band.
The bump size and pitch of these filters are selected
such that the device can be placed directly on an FR4
printed circuit board using conventional assembly tech-
niques. The pin-out for the device features a signal
‘flow through’ design, allowing optimal PCB signal rout-
ing. The solder bump contacts are a 63/37 Sn/Pb alloy
(Sn/Ag/Cu for lead-free finish) and are 0.30 mm in
diameter.
The CM1300 incorporates
OptiGuard
TM
coating which
results in improved reliability at assembly. The device
is available in a space-saving, low-profile Chip Scale
Package with optional lead-free finishing.
