SURFACE MOUNT RESISTOR
RM Series: Thick Film
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 AEC-Q200 qualified and are suitable
for all applications (automotive, lighting, power, etc).

Power rating or current rating is in the case based on continuous full-load at ambient
temperature of 70ºC. For operation at ambient temperature in excess of 70ºC, the load
should be derated in accordance with figure of derating Curve.
Voltage Rating or Current Rating
Resistance Range: >1Ω
Rated Voltage: The resistor shall have a DC continuous working voltage or a RMS AC
continuous working voltage at commercial-line frequency and wave form
corresponding to the power rating, as determined formula as follows:
E = √P x R
E = Rated Voltage (V)
P = Power Rating (W)
