Overview
The CM1442-08CP is an 8-channel EMI filter array with integrated ESD protection, manufactured by onsemi. It utilizes an RC (Pi) low-pass filter topology to suppress electromagnetic interference in high-speed data lines. The device features a total capacitance of 15 pF and resistance of 100 Ohms per channel, housed in a compact 20-WFBGA, WLCSP package. It operates within a temperature range of -40°C to +85°C and provides attenuation of 30 dB at 1 GHz, making it suitable for mobile device applications.
Feature Summary
- Integrates EMI filtering with electrostatic discharge protection in a single component
- Employs RC Pi-filter architecture for effective noise suppression
- Designed for compact surface-mount installation in space-constrained devices
Applications
- Mobile device data line protection
- LCD interface circuits
- Camera module signal lines
Procurement Notes
Verify the specific revision and packaging details against the official datasheet before ordering. Confirm that the 20-WFBGA package dimensions align with your PCB footprint requirements. Ensure compatibility with your assembly process temperatures. Check current availability status as supply conditions may vary. Validate that the electrical parameters meet your system's noise immunity specifications.
Selection Notes
Select this component when simultaneous EMI filtering and ESD protection are required for multiple high-speed channels. The 8-channel configuration reduces board space compared to discrete solutions. Consider the 100 Ohm series resistance impact on signal integrity for your specific data rates. The low capacitance value helps maintain signal quality while providing necessary attenuation.
Part Context
This part belongs to onsemi's CM14xx series of EMI filter arrays designed for portable electronics. These components address the increasing need for signal integrity and protection in miniaturized mobile devices. The series offers various channel counts and filter characteristics to suit different interface requirements such as USB, HDMI, or camera links.
Replacement Considerations
Check for direct pin-compatible alternatives from onsemi or other manufacturers if this part is discontinued. Verify that any substitute maintains the same 8-channel count, RC Pi topology, and WFBGA package. Ensure equivalent ESD performance and attenuation characteristics at 1 GHz.
