EMIF03-SIM05F3

Overview

The EMIF03-SIM05F3 is a highly integrated EMI filter and ESD protection device manufactured by STMicroelectronics. It features a complex array configuration with six channels, designed for surface mount installation in a 9-UFBGA WLCSP package measuring 1.58 x 1.58 mm. The component operates within a temperature range of -30 °C to +85 °C. Key electrical specifications include a maximum reverse standby voltage of 3V, a minimum breakdown voltage of 6V, and a maximum reverse leakage current of 100nA at a test current of 1mA.

Feature Summary

• Provides integrated protection against electrostatic discharge transients and electromagnetic interference emissions
• Designed specifically for safeguarding SIM card interfaces and Single Wire Protocol lines
• Utilizes a compact wafer-level chip scale packaging format for dense board layouts

Applications

• SIM interface protection in mobile devices
• Single Wire Protocol (SWP) line shielding
• Data lines for mobile phones

Procurement Notes

Verify the specific ordering suffix F3 to ensure correct packaging and tape-and-reel specifications. Confirm that the component status is acceptable, as some sources indicate this part may be scheduled for obsolescence. Ensure compatibility with existing PCB footprints for the 9-UFBGA package before procurement.

Selection Notes

Select this component when simultaneous ESD protection and low-pass filtering are required for sensitive smart card interfaces. The integrated RC structure reduces component count compared to discrete solutions. Verify that the 3V standby voltage aligns with the operating voltage levels of the target SIM or SWP circuitry.

Part Context

This device belongs to STMicroelectronics' EMIF series of integrated EMI filters and ESD protectors. It is distinct from other models like the EMIF06-USD05F3 or EMIF06-HSD03F3, which serve different interface types such as USB or microSD. The EMIF03-SIM05F3 is specialized for cellular module interfaces.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to reported obsolescence status, alternative components must be sourced through independent distributor cross-reference tools rather than direct manufacturer substitution lists.
