KBMFXXSC6

® KBMFxxSC6 EMI FILTER AND LINE TERMINATION FOR PS/2 MOUSE OR KEYBOARD PORTS A.S.D.™ MAIN APPLICATION EMI Filter and line termination for mouse and keyboard ports on: - Desktop computers - Notebooks - Workstations - Servers DESCRIPTION On the implementation of computer systems, the radiated and conducted EMI should be kept within the required levels as stated by the FCC regulations. In addition to the requirements of EMC compatibility, the computing devices are required to tolerate ESD events and remain operational without user intervention. The KBMF implements a low pass filter to limit EMI levels and provide ESD protection which exceeds IEC 61000-4-2 level 4 standard. The device also implements the pull up resistors needed to bias the data and clock lines. The package is the SOT23-6L which is ideal for situations where board space is at a premium.
