EMIF02-SPK02F2

Overview

The EMIF02-SPK02F2 is a highly integrated EMI/RFI filter designed for interface line filtering. It features very low resistance of 0.35 Ω and high attenuation of -45 dB at 900 MHz. The device is packaged in a lead-free Flip Chip configuration, occupying minimal PCB space with dimensions of 0.89 mm x 1.26 mm. It operates within a temperature range of -30°C to 125°C and has a Moisture Sensitivity Level (MSL) of 1.

Feature Summary

• Highly integrated design for suppressing EMI/RFI noise in systems subjected to electromagnetic interferences
• Provides ESD protection capabilities alongside signal filtering functions
• Optimized for minimal PCB space consumption through compact Flip Chip packaging

Applications

• Data lines for mobile devices
• Interface line filtering in electronic systems

Procurement Notes

Verify component status carefully as the EMIF02-SPK02F2 is scheduled for obsolescence and will be discontinued by the manufacturer. Confirm availability through authorized distributors or check for end-of-life notifications before initiating procurement processes. Ensure compatibility with existing designs given the discontinuation status.

Selection Notes

Select this component when low insertion loss and high attenuation are required for data lines in mobile applications. The compact FCBGA package suits space-constrained designs. Consider the operating temperature range and MSL rating for environmental compliance. Evaluate alternative components if long-term supply stability is critical due to the planned discontinuation.
