Product Description

The PTFR0402B resistor is a 5.49K ohm SMD resistor from the 0402 thick film series, tailored for surface-mount applications. Designed for compact PCBs, it operates at up to 50V and across a broad temperature range (-55°C to +155°C), ensuring reliability in automotive, industrial, and consumer electronics. With dimensions of 1.0mm x 0.5mm (0402 package), it enables high-density layouts while maintaining stable performance through robust thick film construction. Key advantages include precise resistance tolerance, thermal stability, and compatibility with automated assembly. However, its small size limits power handling to 0.0625W, restricting use to low-power circuits like voltage division, current limiting, or signal conditioning. Ideal for space-constrained designs, it requires careful manual handling during prototyping.
