EMIF03-SIM02F2

Overview

The EMIF03-SIM02F2 is a highly integrated EMI/RFI filter and ESD protection device from STMicroelectronics, designed for SIM card interfaces. It utilizes RC (Pi) low-pass technology with a second-order filter structure across three channels. Key electrical parameters include a total channel resistance of 57 Ohms and a capacitance of 20pF per channel. The component operates within a temperature range of -40°C to 85°C and is housed in an 8-WFBGA package.

Feature Summary

• Provides integrated electromagnetic interference suppression for sensitive data lines
• Includes electrostatic discharge protection capabilities
• Utilizes RC Pi-filter topology for effective noise attenuation

Applications

• SIM card interface circuits
• Mobile device data lines
• Systems exposed to electromagnetic interference

Procurement Notes

Verify the specific suffix 'F2' against the manufacturer's current product status, as some sources indicate this variant may be obsolete. Confirm the exact package type and pinout compatibility with the target PCB layout. Ensure the selected distributor provides valid traceability documentation for original components.

Selection Notes

Select this component when designing SIM interfaces requiring combined EMI filtering and ESD protection in a compact form factor. The 57-ohm resistance and 20pF capacitance values are optimized for high-speed data line integrity. Consider the 8-WFBGA package constraints during thermal and mechanical design phases.

Part Context

This part belongs to the EMIF series of integrated filters from STMicroelectronics. It is specifically engineered for mobile applications where space is limited and signal integrity is critical. The device consolidates multiple passive components into a single surface-mount solution.

Replacement Considerations

Check for active equivalents in the EMIF03 family with similar RC values. Verify if the EMIF03-SIM02M8 or other suffix variants offer updated availability while maintaining functional compatibility.
