RMF Series: Fusible Thick Film Surface Mount
ü
INTRODUCTION
RFE International, Inc. offers a wide range of chip
resistors to meet your application requirements. They are
made with metal glazed thick film on a high purity
ceramic substrate which is overcoated for stability and
protection. These resistors are lead free. The RMF
Series Fusible Resistor is ideal for circuits where a
predictable fusing time is important.
