RP73PF2A25K5BTDF – TE CONNECTIVITY

Overview

The TE Connectivity RP73PF2A25K5BTDF is a high-precision thin-film surface-mount resistor designed for demanding applications where accurate current sensing and voltage division are paramount. Its critical operational characteristic lies in its exceptionally low temperature coefficient of resistance (TCR) of 25 PPM/°C, ensuring stable performance across a wide operating temperature range from -55°C to +155°C. A key design consideration for engineers is balancing the need for high precision with power dissipation; while rated at 250mW, careful thermal management is essential to prevent derating and maintain the tight 0.1% tolerance in higher ambient temperature environments.
