1879659-5 is an axial leaded precision metal film resistor from the TE Connectivity HOLCO series. This resistor features sputter-coated metal alloy films on ceramic substrates with laser spiralling to achieve close tolerance and high stability performance. The series offers tolerances as low as 0.05% and TCR values down to 5ppm/°C, with an operating temperature range of -55°C to +155°C. The resistor includes epoxy coating for environmental and mechanical protection, with insulation resistance greater than 10^12 Ohms at 500V. Common applications include precision instrumentation, industrial equipment, and military systems where long-term stability and accuracy are critical.
