Overview
CM1423 Secure Digital (SD) Card EMI Filter Array with ESD Protection Product Description The CM1423 is an EMI filter array with ESD protection, which http://onsemi.
com integrates six Pi− filters (C−R−C) and four channels of ESD protection.
The CM1423’s filters have component values of 12 pF − 100 W − 12 pF.
The part includes ESD protection diodes on every pin, which provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD).
All the ESD diodes safely dissipate ESD strikes of ±15 kV, beyond the maximum requirement of the IEC 61000−4−2 international WLCSP20 CP SUFFIX CASE 567BZ 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 ±30 kV.
MARKING DIAGRAM This device is particularly well−suited for portable electronics N231 (e.
g.
mobile handsets, PDAs, notebook computers) because of its small package and easy−to−use pin assignments.
In particular, the CM1423 is ideal for EMI filtering and protecting data lines from ESD for the Secure Digital (SD) Card interface slot in mobile N233 handsets.
The CM1423 is an all−inclusive solution for the SD card interface since its EMI filters provide the proper cut−off frequency to attenuate unwanted signals.
The CM1423 is manufactured in a space−saving, low−profile, chip−scale package, and is optionally available with OptiGuardt N231 = CM1423−01CP N233 = CM1423−03CP coating for improved reliability.
It is available with RoHS compliant ORDERING INFORMATION lead−free finishing.
