CM1631 Datasheet | onsemi

Description The CM1631 is a family of pi- style EMI filter arrays with ESD protection, which integrates four, six, or eight filters (C- R- C) in a small form factor, UDFN 0.40 mm pitch package. The CM1631 has ponent values of 15 p F - 100 W - 15 p F per channel with a cut- off frequency of 120 MHz, and can be used in applications with data rates up to 48 Mbps. The device includes ESD diodes on every pin, that provide a very high level of protection for sensitive electronic ponents against possible electrostatic discharge (ESD). The ESD protection diodes safely dissipate ESD strikes of ±15 k V, which is 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 greater than ±30 k V. These devices are particularly well- suited for portable electronics (e.g. wireless handsets, PDAs, notebook puters) because of their small package and easy- to- use pin assignments. In particular, the CM1631 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 CM1631 is housed in space- saving, ultra- low- profile 8- , 12- and 16- lead UDFN packages with a 0.40 mm pitch and is available with lead- free finishing. This smaller size UDFN package provides up to 42% board space saving vs. the 0.50 mm pitch UDFN packages.
