RP73PF2A54K9BTDF – TE CONNECTIVITY

Overview

The TE CONNECTIVITY RP73PF2A54K9BTDF is a precision thin-film chip resistor engineered for demanding circuit applications requiring exceptional stability. With a tight tolerance of ±0.1% and a low temperature coefficient of ±25ppm/°C, it excels in maintaining accurate resistance values across a wide operating temperature range of -55°C to 155°C. A critical design consideration when implementing such high-precision components is the potential for parasitic inductance and capacitance introduced by the PCB layout and termination pads, which can impact high-frequency performance, a factor this 0805 package helps mitigate through its compact form factor.
