FEATURES
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.
