SURFACE MOUNT EMI FILTERS
CHIP FILTERS
NFM51R Series
The NFM51R Series chip is an efficient signal line noise
suppression filter for high-speed digital signal lines where baseband frequencies and noise band frequencies are very close.
Murata Electronics has combined its superior ceramic
technologies with a unique circuit configuration to realize
outstanding noise suppression effect in these applications.
The NFM51R Series assures noise reduction to meet
the specifications of CISPR, FCC, etc.
APPLICATIONS
Noise suppression for compact digital instruments, laptop
personal computers, HDTV, EDTV, portable VTR, etc.
