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 includ-
ing 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. Comm-
ercially 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.
