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.

Pulse Duration
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.
P/N DESIGNATION:
MPF2S - 102 - J T W
RCD Type
Options: P, 37 (leave blank if standard)
Resis. Code: ≤1%: 3 signif. figures & multiplier,
e.g. R100= 0.1Ω, 1R00= 1Ω,1000= 100Ω, 1001= 1KΩ.
Resis. Code 2% - 10%: 2 signif. figures & multiplier,
e.g. R10=.1Ω, R15=.15Ω, 1R0=1Ω,100=10Ω, 102=1K, 103=10KΩ
Tolerance : J= 5% (std), D=0.5%, F=1%, G=2%, K=10%
Packaging : B = Bulk, T = Tape & Reel
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
APPLICATION NOTE
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.
