FEATURES

RCD’s MPF Series utilize special filming processes and

highest grade materials to achieve high power density, yet

the economical MELF package enables pricing well below

rectangular counterparts. The multilayer coating offers

excellent environmental protection and dielectric strength,

and is resistant to industrial solvents, steam and humidity.

ꢀ High power in small body size

ꢀ Low cost MELF design

ꢀ Wide resistance range: 0.1Ω to 10MΩ

ꢀ Standard tolerance: ±5% (available to ±0.1%)

ꢀ Inherent low inductance power film performance

OPTIONS

ꢀ Option P: Increased Pulse Capability

ꢀ Option 37: Group A Screening per Mil-R-39008

ꢀ Numerous design modifications are available (special

marking, matched sets, increased temperature, etc.)

single pulse, with peak voltage levels not exceeding 1KV MPF1, 1.5KV

MPF2S, 2KV MPF2, 2.5KV MPF3S, 3KV MPF3. Max pulse capability for

standard parts (w/o Opt.P) is 50% less. For improved performance and

reliability, a 30-50% pulse derating factor is recommended, or larger for

frequent pulses, high values, etc. (refer to #R-42). Verify selection by

testing under worst-case conditions. Increased pulse levels available.

APPLICATION NOTE

MPF2S

- 102 - J T W

The temp. rise 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 convection, etc). Typical temperature rise at

full rated power is 100°C for MPF1,2,3 and 150°C for MPF2S & 3S

(based on DIN44050 PCB material with 500 sq. mil circuit traces

MPF1, 2, 2S and 1000 sq. mil MPF3,3S). It is recommended to

evaluate product in actual use conditions to ensure the proper

component and PCB layout is utilized.

e.g. R100= 0.1Ω, 1R00= 1Ω,1000= 100Ω, 1001= 1KΩ.

Resis. Code 2% - 10%: 2 signif. figures & multiplier,
