SURFACE MOUNT RESISTORS RMF Series: Fusible Thick Film Surface Mount 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.
