com CM1424 MultiMedia Card EMI Filter Array with ESD Protection Features • • • • • • • • • • Three channels of EMI filtering, each with ESD 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 Lead-free version available Product Description The CM1424 is an EMI filter array integrating 3 pi-filters (C-R-C) and 2 channels of ESD protection.
The 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 connected to the filter ports safely dissipate ESD strikes of ±15kV, beyond the maximum requirement of the IEC61000-4-2 international standard.
Using the MILSTD-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 standard.
This device is particularly well-suited for portable electronics (e.
g.
mobile handsets, PDAs, notebook computers) 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 MultiMedia Card (MMC) slot in mobile handsets.
The CM1424 devices are optionally available with OptiGuard™ coating which results in improved reliability.
The CM1424 is available in space-saving, low-profile, chip-scale packages with optional lead-free finishing.
