EMIF05-1K35F1U: EMI Filtering and Signal Conditioning Integrated Component

The EMIF05-1K35F1U, designed and manufactured by STMicroelectronics, is a highly integrated device that provides EMI filtering and line termination for one signal line. This component is specifically engineered to suppress EMI/RFI noise in electronic circuits. It is commonly utilized in applications requiring high-speed data lines such as USB 2.0, IEEE 1394, and HDMI, ensuring signal integrity and compliance with industry standards.

This compact device combines the functionality of five individual components into one package, making it an ideal solution for space-constrained applications. It includes one line of EMI filtering with an integrated line termination resistor of 33 Ohms, which is the characteristic impedance for USB 2.0 differential lines. The integration of these components not only saves PCB space but also reduces component count and simplifies design.

The EMIF05-1K35F1U is built using STMicroelectronics' advanced IPAD™ (Integrated Passive and Active Devices) technology, which allows for the integration of passive components with active ESD protection circuitry. This technology ensures that the device provides superior ESD protection, with a high level of immunity to ESD strikes exceeding the IEC 61000-4-2 level 4 standard. The component can withstand ESD discharges of ±15 kV (air discharge) and ±8 kV (contact discharge), providing reliable protection for sensitive electronic circuits.

The device comes in a compact SOT23-6L package, making it suitable for high-density boards. It operates over a wide temperature range from -40°C to +85°C, ensuring performance in a variety of environmental conditions. The EMIF05-1K35F1U is RoHS compliant and lead-free, aligning with environmental regulations and allowing for use in green applications.

In summary, the EMIF05-1K35F1U is a versatile and efficient solution for EMI filtering and signal conditioning needs in modern electronic designs. Its integrated approach, robust ESD protection, and small form factor make it a valuable component for designers looking to enhance system reliability and maintain signal integrity in high-speed data applications.
