format product datasheet

The CM1451 is an inductor-capacitor (L-C) based EMI filter array with integrated ESD protection in CSP. The CM1450-06 and CM1450-08 are configured in 6 and 8 channel formats respectively. Each channel is implemented as a 5-pole L-C filter with the component values 9.5pF-17nH-9.5pF-17nF-9.5pF. The CM1451's roll-off frequency at -10dB attenuation is 500MHz. It can be used in applications where the data rates are as high as 200Mbps while providing greater than 35dB attenuation over the 800MHz to 2.7GHz frequency range. The device has ESD protection diodes on every pin that provide a very high level of protection for sensitive electronic components that may be subjected to electrostatic discharge (ESD). The ESD protection diodes connected to the filter ports safely dissipate ESD strikes of ±15kV, exceeding the Level 4 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 ±30kV.

This device is particularly well-suited for portable electronics (e.g. wireless handsets, PDAs) because of its small package and easy-to-use pin assignments. In particular, the CM1451 is ideal for EMI filtering and protecting data and control lines for the LCD display and camera interface in wireless handsets while maintaining the integrity of signals that have rise/fall times as fast as 2ns.

The CM1451 incorporates OptiGuard™, a coating that results in improved reliability at assembly. The CM1451 is available in a space-saving, low-profile Chip Scale Package with optional lead-free finishing

Note: Some of the devices listed here have suggested replacements available. Please see additional information at the end of this page.
