MGP SERIES

MHM SERIES

METAL FILM MELF RESISTORS

Metal film performance, economical price!

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).

OPTIONS

Option S: Increased power (refer to chart below)

Option P: Increased pulse capability

Option F: Flameproof coating (per UL94V0)

Dozens of additional options are available... burn-in, special

marking, non-standard values, high frequency designs,

matched sets, temp. sensitive, zero-ohm jumpers, etc.

Customized components are an RCD specialty!

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.

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.

Industry’s widest selection of metal film MELF resistors-

.1W to .5W, 0.1

Ω to 22MΩ, 0.1% to 5%, 10ppm to 100ppm/°C

Precision performance, excellent environmental stability

Series MHM hermetic sealed is an industry first!
