RESISTORSCAPACITORSCOILSDELAY LINES
MICRO-MINIATURE FILM RESISTORS
Term.W
is RoHS
compliant
MFA SERIES
RoHS
World’s smallest axial-lead resistors!
Subminiature size results in significant space savings
Wide resistance range: 0.5Ω to 470MΩ
Standard tolerance: ±5% (±0.1% through 10% available)
Excellent high frequency and environmental performance
Available with custom marking, mil-spec screening,
tin-lead termination finish, cut & formed leads, etc.
RCD Series MFA resistors were originally developed
to fulfill specialty aerospace requirements but have
found numerous uses in industrial and medical applications,
including hearing aids, oscilloscope probes, high-
frequency circuits, etc. MFA1/16 are the most popular
and economical.
