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. The RMF Series is

AEC-Q200 Qualified.
