RCD Series MGP melf* resistors utilize precision film technology
which is inherently low inductance, low noise, and high stability
even after extended periods. Heavy solder plating assures
excellent solderability and long shelf life. Series MHM offers
hermetically sealed environmental protection and utmost
reliability. MGP series parts are color banded, MHM are alphanu-
merically marked with resistance and tolerance. *Melf = metal
electrode face-bonded (cylindrical component).

APPLICATION NOTE #1: Temperature Rise (T
HS
)
The T
HS
of SM resistors depends largely on heat conduction through the
end terminations, which can vary significantly depending on PCB
material and layout (i.e. pad size, trace area, copper thickness, air flow,
etc.). Typical temp. rise at full rated power is 30-50°C (Opt.S=50-70°C).
APPLICATION NOTE #2: Resistor Selection
MGP resistors are ideal for semi-precision SM applications and are
generally more economical than thin film rectangular chips. For less
critical applications, consider low cost MCF carbon film melf resistors.
For increased performance, especially in high humidity applications
(such as Naval or tropical environments), consider MHM series. If flat
chips are preferred, consider BLU series (precision) or MC series (semi-
precision/ general purpose). For higher power, consider MPF series.
Pulse capability is dependent on res. value, waveform, repetition rate,
current, etc. Chart is a general guide for Opt. P pulse resistant version,
single pulse, with peak voltage levels not exceeding 1KV for MGP55SP,
700V MGP50SP, and 350V MGP45SP. Max pulse capability for standard
parts (w/o Opt.P) is 60% less. For improved performance and reliability,
a 30-50% pulse derating factor is recommended (or larger for frequent
pulses, high values, etc). Consult RCD for application assistance. Verify
selection by evaluating under worst-case conditions.
