NFM61R Series
The T-type chip, NFM61R/RH, is a 3 terminal capacitor
capable of carrying the large currents (2A) required for use
in DC power circuits. This chip series consists of a T-type
filter circuit incorporating a ferrite bead inductor for the
purpose of suppressing undesirable oscillation. The heavy
duty NFM61RH is an improved version of the filter for use in
harsh operating conditions.
APPLICATIONS
■ Switching power supplies
■ Excellent high frequency noise suppression
■ High current applications
