Product Description

California Micro Devices's CM1637 is an EMI filter

array with ESD protection, which integrates either four,

six or eight pi filters (C-R-C). Each CM1637 filter has

component values of 7.5pF-200

include ESD protection diodes on every pin, providing

a very high level of protection for sensitive electronic

components that may be subjected to electrostatic dis-

charge (ESD). The ESD diodes connected to the filter

ports safely dissipate ESD strikes of ±15kV contact dis-

charge, twice the specification requirement of the IEC

61000-4-2, Level 4 international 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. mobile handsets, PDAs, notebook comput-

ers) because of its small package and easy-to-use pin

assignments. In particular, the CM1637 is ideal for EMI

filtering and protecting data lines from ESD in wireless

handsets.

The CM1637 is available in space-saving, ultra-low-

profile, 8-lead, 12-lead and 16-lead 0.4mm pitch UDFN

packages. It is fabricated with California Micro Devices'

Centurion

ing. This new small UDFN package provides up to 42%

board space savings vs. the 0.50mm pitch UDFN pack-

ages.
