Product Description

The PTFR0805B3K90P9 is a PTFR series 3.9kΩ precision resistor in an 0805 surface-mount package, designed for high-reliability applications. As a PTFR0805 resistor, it operates within a voltage range of 0.1V to 150V and withstands temperatures from -55°C to +155°C, suitable for automotive, industrial controls, and consumer electronics. The 3K9 0805 resistor features a ±0.9% tolerance and a power rating of 0.125W, ensuring stable performance in compact circuits. Its thin-film construction provides low noise and excellent temperature stability, though limited by lower surge tolerance compared to wirewound alternatives. The PTFR series 3.9kΩ resistor integrates seamlessly with standard PCB assemblies, eliminating external modules but requiring precise soldering due to its miniature size. Applications include sensor networks, power management, and signal conditioning. Key advantages include high accuracy and durability, while its small footprint limits heat dissipation capacity. Not applicable to battery-driven or display-based systems.
