USBDF01W5

Overview

The USBDF01W5 is a second-order low-pass RC (Pi) EMI filter and line termination designed for USB downstream ports. It integrates two channels with R = 33 Ohms and C = 47pF values. The component provides ESD protection and operates within a temperature range of -40°C to 85°C. It is housed in a compact 5-TSSOP, SC-70-5, or SOT-353 surface-mount package measuring 2.00mm x 1.25mm x 1.09mm. The device achieves an attenuation of -25dB at 900MHz.

Feature Summary

Integrates RC Pi-filter topology for effective EMI suppression on data lines
Provides electrostatic discharge protection for sensitive USB interfaces
Functions as a line termination to meet USB specification requirements

Applications

USB downstream port filtering
EMI suppression for universal serial bus connections
ESD protection for portable electronic devices

Procurement Notes

Verify the specific package variant (5-TSSOP, SC-70-5, or SOT-353) required for your design, as these are listed under the same part number. Confirm that the component status is acceptable for new designs, noting that some sources indicate end-of-life status. Ensure compatibility with RoHS3 specifications if environmental compliance is mandatory for your target market.

Selection Notes

Select this component when designing USB interfaces requiring integrated EMI filtering and ESD protection in a minimal footprint. The fixed 33 Ohm resistance and 47pF capacitance values are optimized for USB signal integrity. Consider the operating temperature range of -40°C to 85°C to ensure reliability in your specific environmental conditions.

Part Context

This component belongs to STMicroelectronics' IPAD series of EMI filters. It is specifically engineered to address electromagnetic interference issues in high-speed digital interfaces like USB. The integration of filtering and termination functions reduces the need for discrete components, simplifying the PCB layout and saving space.
