RP73PF1J3K57BTDF – TE CONNECTIVITY

Overview

The TE Connectivity RP73PF1J3K57BTDF is a high-precision thin-film surface-mount resistor designed for demanding circuit applications. Its critical operational characteristic lies in its exceptional 0.1% tolerance and a tight 25 PPM/°C temperature coefficient, ensuring stable resistance values across a wide operating range from -55°C to +155°C. A key design consideration when utilizing such precision components is the potential for parasitic inductance and capacitance introduced by the PCB layout, which can impact high-frequency performance despite the resistor’s inherent low noise characteristics. This 1608 (0603) metric size component offers a robust 100mW power rating for its compact footprint.
