PULSE CAPABILITY

MPF3P

MPF2P, 3SP

MPF2SP

MPF1P

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 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.

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.

P/N DESIGNATION:

RCD Type

Tolerance : J= 5% (std), D=0.5%, F=1%, G=2%, K=10%

Packaging : B = Bulk, T = Tape & Reel

MPF2S

- 102 - J

T W

Options: P, 37 (leave blank if standard)

Resis. Code:

≤≤≤≤≤1%: 3 signif. figures & multiplier,

e.g. R100= 0.1

Ω, 1R00= 1Ω,1000= 100Ω, 1001= 1KΩ.

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

e.g. R10=.1

Ω, R15=.15Ω, 1R0=1Ω,100=10Ω, 102=1K, 103=10KΩ

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

in which case RCD will select based on lowest price and quickest delivery

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.
