CSPEMI204FCTAG

Overview

The CSPEMI204FCTAG is a two-channel EMI filter circuit with integrated ESD protection, designed for 3V applications. It provides 45 dB of shielding attenuation within the 900 MHz frequency range. The device utilizes MouseReel packaging and has a factory pack quantity of 5000 units.

Feature Summary

• Integrates EMI filtering with electrostatic discharge (ESD) protection in a single component
• Provides high shielding attenuation of 45 dB for signal integrity
• Optimized for low-voltage 3V system operation

Applications

• High-speed data line protection in consumer electronics
• Signal conditioning for communication interfaces operating near 900 MHz
• ESD mitigation in compact mobile devices

Procurement Notes

Verify current availability status as the manufacturer has scheduled this part for obsolescence. Confirm final unit pricing and lead times directly with authorized distributors before committing to orders. Ensure compatibility with existing PCB footprints and design specifications during the transition planning phase.

Selection Notes

Select this component when simultaneous EMI suppression and ESD protection are required for 3V logic lines. The 45 dB attenuation at 900 MHz makes it suitable for specific RF-adjacent digital signals. Evaluate the trade-off between its small form factor and the impending end-of-life status against long-term supply chain stability requirements.

Part Context

This component belongs to onsemi's family of passive EMI/RFI filter circuits. It addresses the growing need for compact, multi-functional protection solutions in space-constrained portable electronics. The integration of filtering and protection reduces bill-of-materials count compared to discrete implementations.

Replacement Considerations

No public confirmed substitute part numbers are available. Due to the scheduled obsolescence status, alternative sourcing strategies or redesign efforts may be necessary to maintain production continuity.
