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 OptiGuardcoating 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.
