The RTT251R80FTE is a Chip Resistor - Surface Mount manufactured by RALEC. It is a 1.8 Ohm ± 1% 1W 2512 RoHS (Restriction of Hazardous Substances) part. It is made from thick film technology on a high temperature co-fired ceramic substrate, with Ni-Pd termination. The resistor features excellent temperature stability and low TCR (Thermal Change Rate). It is suitable for use in a wide range of very demanding, high power, temperature-sensitive, and noise-critical applications, such as automotive, industrial, telecom, and medical equipment. The resistor is RoHS Compliant and is designed to meet the electrical requirements of today’s surface mount thermal printer designs.
