Product Description

CAMD's CSPEMI400 is an EMI filter array with ESD

protection, which integrates three pi filters (C-R-C) and

two additional channels of ESD protection.

CSPEMI400 has component values of 20pF-47Ω-

20pF, and 20pF-100Ω-20pF. The parts include ava-

lanche-type ESD diodes on every pin, which provide 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 ±10kV, exceeding

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 ±25kV.

The ESD diodes on pins A4 and C4 ports are designed

and characterized to safely dissipate ESD strikes of

±10kV, well beyond the maximum requirement of the

IEC 61000-4-2 international standard.

This device is particularly well suited for portable elec-

tronics (e.g. mobile handsets, PDAs, notebook com-

puters) because of its small package format and easy-

to-use pin assignments. In particular, the CSPEMI400

is ideal for EMI filtering and protecting data lines from

ESD for the SIM card slot in mobile handsets.

The CSPEMI400 is available in a space-saving, low-

profile Chip Scale Package with optional lead-free fin-

ishing.
