Axial Leaded Precision Resistors Type HOLCO Series Key Features Ultra Precision - Down To 0.05% Matched Sets Available To 2ppm/C High Pulse Withstand Low Reactance Low TCR - Down To 5ppm/C Long Term Stability Up To 1 Watt At 70C Released To CECC 40101 004, 030 And 804 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.
