Product Description

The PTFR0402 resistor, also known as the PTFR5K49 chip resistor, is a surface-mount device with a 5.49K Ohm resistance in a compact 0402 package (1.0mm x 0.5mm). Designed for precision circuit applications, it supports a voltage range up to 50V and operates within -55°C to +155°C, ensuring reliability in automotive, industrial, and consumer electronics. As a two-terminal passive component, it lacks dedicated communication interfaces but integrates seamlessly into analog/digital circuits for voltage division, current limiting, or signal conditioning. Key advantages include ±1% tolerance, low temperature coefficient (≤100ppm/°C), and stable performance under thermal stress. Its ultra-small size, however, limits power dissipation to 0.063W and requires careful PCB layout for heat management. Not designed for battery-driven systems, display interfaces, or proximity sensing applications.
