At 70°C

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.
