MFD Metal Film Resistors

Product catalog summary

Features and Construction:
MFD Metal Film Resistors are designed with a ceramic core made of alumina ceramic, a trimming line, a nickel alloy resistor element, tinned iron cap terminals, tinned annealed copper wire leads, epoxy molding, and laser marking. These resistors offer precision tolerance as tight as ±0.02%, excellent stability, reliability, and superior electrical TCR performance narrowed to ±5PPM/℃. They are lead-free and RoHS compliant, covering all general type resistors.

Specifications:
The MFD series includes various power ratings: 1/8W, 1/4W, 1/2W, 3/4W, and 1W. Resistance tolerance options include P=±0.02%, W=±0.05%, B=±0.1%, D=±0.5%, and F=±1%. TCR options are C8=3ppm/℃, C7=5ppm/℃, C6=10ppm/℃, C5=15ppm/℃, and C3=25ppm/℃. Resistance values range from 10Ω to 1MΩ.

Applications:
These resistors are suitable for medical electronics, telecom, measuring and calibration equipment, precision instruments, and avionics.

Dimensions:
Dimensions vary by power rating, with specific measurements for length (L), diameter (D), height (H), and lead diameter (d) provided for each power rating.

Performance Characteristics:
Key performance characteristics include temperature coefficient of resistance (T.C.R.), short time overload, insulation resistance, endurance, damp heat with load, solderability, resistance to soldering heat, terminal strength, pulse overload, temperature cycle, and resistance to solvent. Each characteristic is tested according to JIS C 5201-1 standards.

Ordering Information:
Ordering codes are structured to include series name, power rating, resistance tolerance, TCR, and resistance value.
