Part Description: MI FILTER AND LINE TERMINATION FOR USB DOWNSTREAM PORTS


Part Details:

USBDFxxW5 EMI filter and line termination for USB downstream ports Applications EMI Filter and line termination for USB downstream ports on: Desktop computer SOT323-5L Notebooks Workstations Functional diagram USB Hubs Features Rt D+ In D+ Out Monolithic device with recommended line Ct Rd termination for USB downstream ports Integrated Rt series termination and Ct Gnd bypassing capacitors. Integrated ESD protection Ct Rd Small package size D- In D- Out Rt Description Rt Rd Ct The USB specification requires USB downstream USBDF01W5 33 15 k 47 pF ports to be terminated with pull-down resistors from the D+ and D- lines to ground. On the USBDF02W5 15 15 k 47 pF implementation of USB systems, the radiated and Tolerance ±10% ±10% ±20% conducted EMI should be kept within the required levels as stated by the FCC regulations. In addition to the requirements of termination and Order codes EMC compatibility, the computing devices are required to be tested for ESD susceptibility. Part number Marking The USBDFxxW5 provides the recommended line USBDF01W5 UD1
