CM1406-04DE

Overview

The CM1406-04DE is a four-channel EMI filter array with integrated ESD protection, manufactured by onsemi. It utilizes an RC Pi-filter topology (C-R-C) designed for signal line conditioning. Key electrical parameters include a resistance of 200 Ohms and capacitance of 15 pF per channel. The device operates within a frequency range of 800 MHz to 2.7 GHz, offering 30 dB attenuation at a cutoff frequency of 350 MHz. It is housed in a compact WDFN-8 package measuring 2 mm x 2 mm x 0.8 mm, suitable for surface mount technology, with an operating temperature range from -40°C to +85°C.

Feature Summary

• Integrates four independent RC Pi-filter channels for effective common-mode noise suppression.
• Provides electrostatic discharge (ESD) protection to safeguard sensitive downstream circuitry.
• Features a low-profile WDFN-8 package optimized for space-constrained mobile designs.

Applications

• Data lines for mobile devices
• LCD and camera interfaces
• High-speed digital signal protection

Procurement Notes

Verify the specific suffix 'DE' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Confirm availability as distribution statuses may vary. Ensure the selected component matches the required thermal and electrical specifications for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring simultaneous EMI filtering and ESD protection for multiple data lines. The 200 Ohm series resistance and 15 pF shunt capacitance are suitable for high-speed interfaces where signal integrity must be maintained while attenuating out-of-band noise. Consider the WDFN-8 footprint constraints during PCB layout planning.
