ECONOMICAL 1 WATT TO 3 WATT POWER FILM MELF RESISTORS
RESISTORS CAPACITORS COILS DELAY LINES
MPF SERIES
RoHS
Term.W is RoHS compliant & 260°C compatible
FEATURES
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
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.

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.
