The 1879354-7 is a metal film power resistor from the RR Series, designed for applications requiring high power dissipation in a compact package. This component provides a resistance of 1 kΩ with a ±5% tolerance and a maximum power dissipation of 1W at an ambient temperature of 70°C. It features a limiting voltage of 350V, a temperature coefficient of +300ppm/°C, and is constructed from a metal alloy film on a high-grade ceramic body with a non-flammable protective coating. Due to its high stability, reliability, and good performance in pulse applications, it is well-suited for a variety of electronic circuits.
