CM1484
CM1484 is Dual Channel EMI Filter manufactured by onsemi.
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 ponent values of 11 p F
- 100 W
- 11 p F 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 ponents that may be subjected to electrostatic discharge (ESD). The ESD protection diodes safely dissipate ESD strikes of ±15 k V, 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 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 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.
