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. Offered
with release to BS CECC 40101 004, 030 and 804 the H8 is available via distribution.
