Product Description
CAMD's CSPEMI606 and CSPEMI608 are EMI filter
arrays with ESD protection, which integrate six and
eight Pi- filters (C-R-C), respectively. The CSPEMI60x
has component values of 15pF-100Ω-15pF. These
devices include ESD protection diodes on every pin,
which provide a very high level of protection for sensi-
tive electronic components that may be subjected to
electrostatic discharge (ESD). The ESD diodes con-
nected to the filter ports are designed and character-
ized to safely dissipate ESD strikes of ±15kV, beyond
the maximum requirement of the IEC 61000-4-2 inter-
national standard. Using the MIL-STD-883 (Method
3015) specification for Human Body Model (HBM)
ESD, the pins are protected for contact discharges at
greater than ±30kV.
This device is particularly well suited for portable elec-
tronics (e.g. wireless handsets, PDAs, notebook com-
puters) because of its small package format and easy-
to-use pin assignments. In particular, the CSPEMI60x
is ideal for EMI filtering and protecting data lines from
ESD for the LCD display in clamshell handsets.
The CSPEMI606 and CSPEMI608 are available in
space-saving, low-profile chip-scale packages with
optional lead-free finishing.
