The Holco range of Precision Metal Film Resistors meets the requirement for
economically priced components for industrial and military applications. The
manufacturing facility utilises closely controlled production processes including
the sputter coating of metal alloy films to ceramic substrates, and laser spiralling
to achieve close tolerance and high stability resistors. An epoxy coating is
applied for environmental and mechanical protection. Commercially the Series is
available in two case sizes, from 1 ohm to 4M ohms, tolerances from 0.05% to
1% and TCR's from 5ppm/°C to 100ppm/°C.
