The PTFR0603B51R0P9 is a SMD (Surface Mount Device) resistor manufactured by ResistorToday. It is a 1/10W, 0603 size, 51Ohms, ±0.1% precision low TCR (Temperature Coefficient Resistor) that is compliant with RoHS (Restriction of Hazardous Substances). It is designed for use in high precsion applications, such as audio/video equipment, medical and communication equipment, and military systems. The PTFR0603B51R0P9 has a TCR of ±25ppm/°C, making it suitable for applications where very low Temperature Coefficient is required. High power dissipation, good resistance stability, and high reliability are assured by using thick carbon film technology. The resistor can be soldered using standard soldering and can be easily mounted onto printed circuit boards.
