EMIF02-SPK03F2

Overview

The EMIF02-SPK03F2 is a 2-channel EMI filter and ESD protection device from STMicroelectronics, designed for speaker phone interface line filtering. It features a low-pass LC (Pi) filter configuration with a capacitance of 250pF and a current rating of 800 mA. The component provides -40 dB attenuation at 900 MHz and -60 dB crosstalk in the audio band. Packaged in a 5-WFBGA/FCBGA format with a 0.5 mm pitch WLCSP footprint measuring 0.89 x 1.26 mm and a thickness of 0.6 mm after reflow, it operates within a temperature range of -30°C to 85°C.

Feature Summary

• Provides symmetrical 2-channel low-pass filtering for high-efficiency EMI suppression on interface lines.
• Integrates ESD protection circuitry compliant with IEC 61000-4-2 Level 4 standards for input pins.
• Utilizes monolithic integration and wafer-level packaging to minimize parasitic elements and PCB space consumption.

Applications

• Speaker phone interface line filtering
• Audio signal path protection
• Mobile device EMI suppression

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or certified partners. Confirm package integrity and lead condition upon receipt. Ensure storage conditions comply with moisture sensitivity levels specified in the datasheet. Cross-reference part numbers carefully as this specific model may be obsolete; check for valid replacement alternatives if current stock is unavailable.

Selection Notes

Select this component when compact form factor and integrated ESD protection are required for audio interfaces. The 250pF capacitance and 800mA rating suit low-power audio lines. Consider the 0.5mm pitch WLCSP package for tight space constraints. Verify compatibility with operating temperatures ranging from -30°C to 85°C for target applications.

Part Context

This device belongs to the EMIF02 series of highly integrated EMI filters. It shares design principles with models like the EMIF02-USB03F2 but is optimized for speaker and audio applications rather than USB ports. The series emphasizes miniaturization through wafer-level packaging while maintaining high attenuation performance for sensitive analog signals.

Replacement Considerations

Public documentation indicates this specific part number is obsolete. Consult STMicroelectronics for qualified replacement components within the EMIF02 family that offer compatible pinouts and electrical characteristics for speaker phone applications.
