RP73PF2A84R5BTDF – TE CONNECTIVITY

Overview

The TE CONNECTIVITY RP73PF2A84R5BTDF is a high-precision 0805 (2012 metric) thin-film surface-mount resistor designed for demanding applications where accurate current sensing or voltage division is critical. Its defining characteristic is the exceptionally tight 0.1% absolute tolerance, coupled with a low 25 PPM/°C temperature coefficient, ensuring stable resistance values across its wide operating temperature range of -55°C to +155°C. A key design consideration for engineers is balancing this precision with the 250mW power rating; while robust for its size, continuous operation near its power limit will necessitate careful thermal management to prevent drift and maintain the specified accuracy, a common trade-off in miniaturized precision components.
