BGF 109L E6328

Overview

The Infineon BGF 109L E6328 is a discontinued LC EMI filter circuit designed for mobile device data lines. It features a 5th order low-pass configuration with ten channels and integrated ESD protection. The component utilizes a 24-UFBGA surface-mount package measuring 2.10mm x 2.10mm. Key electrical specifications include a total capacitance of 28pF, a channel resistance of 90 Ohms, and an attenuation value of 45dB within the 800MHz to 2.2GHz frequency range. It operates within a temperature range of -40°C to 85°C.

Feature Summary

• Integrates EMI filtering with electrostatic discharge protection in a single compact package
• Provides high attenuation performance across wideband radio frequencies
• Supports multi-channel signal processing for complex mobile interface requirements

Applications

• Mobile device data line protection
• LCD filter arrays requiring EMI suppression
• SIM card interface filtering systems

Procurement Notes

This component is officially discontinued and no longer manufactured by Infineon Technologies. Verification of availability should focus on secondary market distributors or surplus suppliers rather than direct manufacturer channels. Buyers must confirm the authenticity and storage history of existing stock due to the end-of-life status. Cross-referencing official obsolescence notices is recommended before procurement decisions.

Selection Notes

Designers should evaluate alternative components from the same family or newer generations that offer similar filtering characteristics and pin compatibility. Since this part is obsolete, supply chain stability is a primary concern. Selection criteria must prioritize verified substitutes that meet the original 28pF total capacitance and 45dB attenuation requirements while ensuring the 24-UFBGA footprint remains suitable for the target PCB layout.

Part Context

The BGF 109L E6328 belongs to Infineon's BGF series of EMI filter circuits, specifically engineered for consumer electronics. It addresses the growing need for compact, high-performance filtering solutions in space-constrained mobile devices. This component represents a specialized solution for managing electromagnetic interference on high-speed data interfaces while providing necessary transient voltage suppression.

Replacement Considerations

Official documentation lists BGF 109C E6328 as a related variant within the same discontinuation context. Designers should verify functional equivalence and pinout compatibility when considering these alternatives. No other specific substitute part numbers are confirmed in public records.
