World’s smallest axial-lead resistors!
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, highfrequency circuits, etc. MFA1/16 are the most popular
and economical.
