CM1436-04DE

Overview

The CM1436-04DE is a four-channel EMI filter array with integrated ESD protection, manufactured by onsemi. It utilizes an RC (Pi) filter topology, where each channel integrates component values of 15 pF capacitance and 200 Ohms resistance. The device operates within a frequency range of 800 MHz to 6 GHz and provides 30 dB attenuation. It features a WDFN-8 surface-mount package measuring 1.7 mm in length, 1.35 mm in width, and 0.75 mm in height. The operational temperature range spans from -40°C to +85°C.

Feature Summary

• Integrates four independent pi-filter channels for simultaneous signal line protection
• Combines electromagnetic interference filtering with electrostatic discharge protection capabilities
• Utilizes a compact surface-mount footprint designed for space-constrained mobile applications

Applications

• Data lines in mobile devices
• LCD interface circuits
• Camera module signal paths

Procurement Notes

Verify the specific suffix DE against official datasheets to confirm package dimensions and pin configuration. Confirm current lifecycle status as discontinued before finalizing design-in decisions. Ensure compatibility with existing PCB layout constraints regarding the WDFN-8 footprint and thermal requirements.

Selection Notes

Select this component when designing high-speed data interfaces requiring combined EMI suppression and ESD robustness. The RC topology suits applications where low insertion loss is prioritized over steep roll-off characteristics. Evaluate the 15 pF capacitance value against signal integrity requirements for the specific data rate being supported.
