CMD&primes CM1470 is a family of series inductor networks providing EMI filtering for applications that are sensitive to signal integrity such as high-resolution camera interfaces. The CM1470 is configured in 4, 6 and 8 channel formats. Each channel is implemented as a single inductor element where the component value is 17nH. The CM1470 will help suppress EMI radiation to the external environment. The parts integrate ESD diodes on every pin to provide protection during the manufacturing process when the device is placed on the PCB from a pick-and-place machine. The ESD protection diodes safely dissipate ESD strikes of ±2kV, per the MIL-STD-883 (Method 3015) specification for Human Body Model (HBM) ESD.

CM1470 is particularly well suited for portable electronics (e.g. wireless handsets, PDAs) because of its small package format and easy-to-use pin assignments. In particular, the CM1470 is ideal for EMI filtering data and control lines in camera modules where it is placed near the transmission source on a flexible PCB. The CM1470 level of performance (i.e. cutoff frequency and attenuation level) can be tuned with external signal trace capacitance.

The CM1470 incorporates OptiGuard™ which results in improved reliability at assembly. The CM1470 is available in a space-saving, low-profile Chip Scale Package with lead-free finishing.
