CM1409
LCD and Camera EMI Filter Array with ESD Protection
Product Description
The CM1409 is a family of pi−style EMI filter arrays with ESD protection, which integrates either six or eight filters (C−R−C) in a small form factor, WDFN 0.50 mm pitch package. The CM1409 has component values of 15 pF − 100 W − 15 pF per channel. The CM1409 has a cut−off frequency of 110 MHz and can be used in applications with data rates up to 44 Mbps. The parts include ESD diodes on every pin, which provide a very high level of protection for sensitive electronic components against electrostatic discharge (ESD). The ESD protected diodes safely dissipate ESD strikes of ±15 kV, which even exceeds 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 ±30 kV.
These devices are particularly well−suited for portable electronics (e.g. wireless handsets, PDAs, notebook computers) because of their small package and easy−to−use pin assignments. In particular, the CM1409 is ideal for EMI filtering and protecting data and control lines for the I/O data ports, LCD display and camera interface in mobile handsets.
The CM1409 is housed in space−saving, low−profile 12− and 16−lead WDFN packages with a 0.50 mm pitch, RoHS−compliant, lead−free finishing.
