The CM1406-08DE is a sophisticated RC (Pi) filter designed by AMI Semiconductor/onsemi, specifically engineered for high-performance electromagnetic interference (EMI) suppression in mobile device data lines. This advanced discrete semiconductor device offers comprehensive signal integrity protection through its innovative 2nd-order low-pass filter topology.
Primarily targeting mobile communication and data transmission applications, the filter provides exceptional electromagnetic compatibility by delivering 30dB attenuation across the 800MHz to 3GHz frequency range. Its compact 16-WFDFN exposed pad package, measuring just 0.157" x 0.063" (4.00mm x 1.60mm), enables seamless integration into space-constrained electronic designs.
The filter features eight independent channels with consistent electrical characteristics, including a 200-ohm resistance and 15pF capacitance. Its robust design supports reliable operation across a wide temperature range from -40°C to 85°C, making it suitable for demanding electronic environments. Built-in electrostatic discharge (ESD) protection enhances the device's durability and performance reliability.
Key advantages include its surface-mount configuration, minimal footprint, high-frequency noise suppression, and comprehensive ESD protection. The filter's center/cutoff frequency of 105MHz ensures effective signal conditioning while maintaining signal integrity in complex electronic systems.
Alternative or equivalent models might include similar RC filters from manufacturers like Murata, TDK, and Würth Elektronik, though the specific CM1406 series offers unique characteristics that set it apart in precision and performance.
Ideal applications encompass mobile devices, telecommunications equipment, wireless communication systems, and other high-frequency electronic platforms requiring advanced signal filtering and electromagnetic interference mitigation.
