1-1879628-4 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%, TCR options from 5ppm/°C to 100ppm/°C, and operates over an ambient temperature range of -55°C to +155°C. Performance characteristics include voltage coefficient of resistance less than 5ppm/Volt, insulation resistance greater than 10¹² Ohms at 500V, and excellent long-term stability. These precision resistors are ideal for industrial and military applications requiring high accuracy and reliability.
