EMIF04-2005QCF

Overview

The EMIF04-2005QCF is a highly integrated EMI filter and ESD protection device designed for data lines in mobile devices. It features four channels with an LC configuration of R=200 Ohms and C=45pF per line. The component provides surface mount mounting in an 8-TFDFN exposed pad package, measuring 0.079 inches (approximately 2mm) in length and width. It operates within a temperature range of -40°C to +85°C and includes built-in ESD protection capabilities.

Feature Summary

• Highly integrated design combining EMI/RFI noise suppression with electrostatic discharge protection
• Four-channel architecture optimized for high-speed data line applications
• Compact footprint suitable for space-constrained mobile device layouts

Applications

• Data lines for mobile devices
• Systems subjected to electromagnetic interferences
• High-speed interface protection

Procurement Notes

Verify the specific suffix QCF against official STMicroelectronics documentation to confirm pinout and electrical characteristics. Ensure compatibility with existing PCB footprints by checking the 8-TFDFN exposed pad dimensions. Confirm that the 200 Ohm resistance and 45pF capacitance values meet the signal integrity requirements of the target application before finalizing procurement.

Selection Notes

Select this component when simultaneous EMI filtering and ESD protection are required for multiple data lines in a compact form factor. The integrated LC network simplifies board layout compared to discrete components. Verify that the operating temperature range of -40°C to +85°C aligns with the environmental conditions of the end product.

Part Context

This part belongs to the EMIF series from STMicroelectronics, which focuses on providing compact solutions for electromagnetic interference suppression. These devices are engineered to replace multiple discrete components, thereby reducing assembly complexity and saving valuable board space in portable electronics and other sensitive electronic systems.

Replacement Considerations

Check for direct substitutes within the EMIF series or equivalent offerings from other manufacturers that match the 8-TFDFN package and 4-channel configuration. Ensure any replacement maintains the same R=200 Ohm and C=45pF specifications to preserve circuit performance.
