SMD RESISTOR - HIGH POWER
RMH Series: Thick Film
INTRODUCTION
The RMH Series is a higher power (high wattage) version
of the basic RM Series thick film surface mount resistor.
RMH Series is made with a specially formulated substrate
and with an advanced process used to deposit the film.
As a result, power ratings can surpass standard series.
These resistors are AEC-Q200 qualified and 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 = vP x R
E = Rated Voltage (V)
P = Power Rating (W)
