FEATURES
World’s smallest axial-lead resistors!
ꢀ 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
RCD Series MFAresistors 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.
MFA1/10 & MFA1/20 are color banded, MFA1/16 is
stamped with 3-digit resistance code.
