EMIF03-SIM06F3: EMI Filter and ESD Protection for SIM Card Interfaces

The EMIF03-SIM06F3 is a highly integrated solution designed by STMicroelectronics to provide both Electromagnetic Interference (EMI) filtering and Electrostatic Discharge (ESD) protection specifically for SIM card interfaces in mobile and communication devices. This product is engineered to ensure signal integrity while safeguarding sensitive components from the potentially damaging effects of EMI and ESD.

Key Features

• EMI Filtering: The device includes a set of high-quality filters that significantly reduce the EMI noise on the SIM card interface lines, thus preserving the performance and reliability of communication.
• ESD Protection: It offers robust ESD protection that meets the IEC 61000-4-2 standard, safeguarding the SIM card interface from electrostatic discharges up to 15 kV, thereby preventing damage to the electronic circuitry.
• High Integration: The EMIF03-SIM06F3 integrates 3 filter circuits with ESD protection, minimizing the need for additional components and simplifying the design process for engineers.
• Small Form Factor: Packaged in a compact µQFN-6L, the device is ideal for space-constrained applications, enabling designers to maintain slim profiles in their product designs.
• Low Pass Filter: The built-in low pass filter provides excellent attenuation, contributing to the overall electromagnetic compatibility (EMC) of the end application.
• Low Clamping Voltage: Its low clamping voltage ensures that even under ESD stress, the voltage exposure to the protected lines remains within safe limits.
