Overview
The CM1622-08DE is an eight-channel EMI filter circuit with integrated electrostatic discharge (ESD) protection, designed for high-speed data lines. It utilizes a Pi-style LC network topology within a compact uDFN-16 package measuring 3.4 mm x 1.45 mm x 0.55 mm. Key electrical parameters include a capacitance of 16.5 pF, inductance of 12 nH, and attenuation of 35 dB across the 1 GHz to 3 GHz frequency range. The device operates between -40°C and +85°C.
Feature Summary
- Integrates eight channels of EMI filtering with built-in ESD protection capabilities
- Employs a Pi-style capacitor-resistor-capacitor (C-R-C) network architecture
- Utilizes an ultra-thin uDFN-16 package for space-constrained applications
Applications
- LCD display interface protection
- Camera module signal line filtering
- High-speed data bus EMI suppression
Procurement Notes
Verify component authenticity through authorized onsemi distributors or direct manufacturer channels. Confirm the specific ordering suffix matches project requirements. Check current availability status as supply conditions may vary. Ensure storage and handling procedures comply with moisture sensitivity level ratings specified in the official datasheet to maintain device integrity during assembly.
Selection Notes
Select this component when simultaneous EMI suppression and ESD protection are required for multiple differential or single-ended lines. The low parasitic capacitance and high attenuation characteristics make it suitable for bandwidth-sensitive interfaces. Evaluate the physical footprint constraints against the uDFN-16 dimensions to ensure compatibility with the printed circuit board layout and soldering process specifications.
Part Context
This component belongs to the CM1690 series of EMI filter arrays manufactured by onsemi. It is part of a family of solutions designed for protecting sensitive electronic interfaces from electromagnetic interference and static discharge events. The product line targets mobile and consumer electronics markets where signal integrity and component miniaturization are critical design priorities.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical specifications before considering alternative components from other manufacturers.
