MICRO-MINIATURE FILM RESISTORS
World’s smallest axial-lead resistors!
RCD Series MFA resistors were originally developed
for use in aerospace requirements but have found
numerous uses in industrial and medical applications,
including hearing aids and high-frequency circuits.
MF A1/10 & MF A1/20 are color banded, MF A1/16 is
stamped with 3-digit resistance code.
Subminiature size results in significant space
savings, enabling high density circuits
Wide resistance range: 1Ω to 10MΩ
Standard tolerances: ±1%, 2%, 5%, 10%
(±0.5% available)
Excellent high frequency performance
Excellent environmental performance
Available with cut & formed leads
