Metal film performance, economical price!

ꢀ Industry’s widest selection of metal film MELF resistors-

.1W to .5W, 0.1Ω to 22MΩ, 0.1% to 5%, 10ppm to 100ppm/°C

ꢀ Low cost, quick delivery (available on SWIFT^TMprogram)

ꢀ Precision performance, excellent environmental stability

ꢀ Series MHM hermetic sealed is an industry first!

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.

Typical performance levels listed are for standard products from 10Ω to 1M.

Consult factory for performance levels of extended range and modified designs.

** To ensure utmost reliability, care should be taken to avoid potential sources of

ionic contamination

APPLICATION NOTE #1: Temperature Rise (T_HS

)

The T_HSof 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.

e.g. R10= 0.1Ω, 1R0= 1Ω,100= 10Ω,101=100Ω,102= 1K, 103=10K.

Tolerance: F=1% (std), B=0.1%, C=.25%, D=.5%, G=2%, J=5%

Optional TC: 10=10ppm, 25=25ppm, 50=50ppm (leave blank if std)

Termination: W= Lead-free, Q= Tin/Lead (leave blank if either is acceptable)
