CM1484 Dual Channel EMI Filter with ESD Protection Product Description The CM1484 is a two channel pi-style EMI filter array with ESD protection, housed in a 5−lead SC−70 package. The CM1484 has component values of 11 pF − 100 W − 11 pF per channel. The CM1484 has a cut−off frequency of 220 MHz and can be used in applications with data rates up to 80 Mbps. The parts include 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 protection diodes safely dissipate ESD strikes of ±15 kV, well 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 ±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 CM1484 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 CM1484 is housed in a small, 5−lead SC−70 package and is available with lead-free finishing.
