CM1424

MultiMedia Card EMI Filter Array with ESD Protection

Product Description

Features

•

Three channels of EMI filtering, each with ESD

The CM1424 is an EMI filter array integrating 3 pi-filters

(C-R-C) and 2 channels of ESD protection. The

protection

•

Two channels of ESD protection

Flow-through routing for MMC interface

15kV ESD protection (IEC 61000-4-2, contact

discharge)

30kV ESD protection (HBM)

Greater than 30dB of attenuation at 1GHz

Chip Scale Package features extremely low

lead inductance for optimum filter and ESD

performance

10-bump, 1.998mm x 1.458mm footprint Chip

Scale Package (CSP)

Available with OptiGuard™ coating for improved

reliability

CM1424 has component values of 12pF-100Ω -12pF.

The parts include avalanche-type ESD diodes on every

pin, which provide a very high level of protection for

sensitive electronic components that may be subjected

to electrostatic discharge (ESD). The ESD diodes con-

nected to the filter ports safely dissipate ESD strikes of

15kV, beyond the maximum requirement of the

IEC61000-4-2 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.

•

The ESD diodes on pins A2 and C2 safely dissipate

ESD strikes of 15kV, well beyond the maximum

requirement of the IEC 61000-4-2 international stan-

dard.

Lead-free version available

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 CM1424 is ideal for EMI

filtering and protecting data lines from ESD for the Mul-

tiMedia Card (MMC) slot in mobile handsets.

Applications

•

MultiMedia Card (MMC) slot in mobile handsets

and other handheld devices such as digital cam-

eras and MP3 players

•

I/O port protection for mobile handsets, notebook

computers, PDAs etc.

EMI filtering for data ports in cell phones, PDAs or

notebook computers

The CM1424 devices are optionally available with Opti-

Guard

™ coating which results in improved reliability.

The CM1424 is available in space-saving, low-profile,

chip-scale packages with optional lead-free finishing.
