Product Description

The PTFR0402B1K78N9 is a high-precision 1.78K ohm resistor designed for compact electronic applications. Utilizing 0402 thin film resistor technology, it offers a ±0.1% tolerance and a low temperature coefficient of ±25 ppm/°C, ensuring stable performance across a wide operating temperature range of -55°C to +155°C. Rated for 1/16W power dissipation, it operates within a 50V maximum voltage. Ideal for precision circuits in consumer electronics, industrial automation, and automotive systems, this surface-mount resistor excels in space-constrained designs due to its miniature 0402 footprint (1.0mm x 0.5mm). Key advantages include excellent stability under thermal stress and moisture resistance, though its small size limits heat dissipation capabilities. Not applicable to battery capacity or display integration as a passive component.
