RP73PF2A619RBTDF – TE CONNECTIVITY

Overview

The TE CONNECTIVITY RP73PF2A619RBTDF is a high-precision 619 Ohm thin-film surface-mount resistor designed for applications demanding stringent linearity and minimal drift. Its critical operational characteristic lies in its exceptionally low 25 PPM/°C temperature coefficient, ensuring stable resistance values across a wide thermal range from -55°C to +155°C. A key design consideration when utilizing such precision components is the trade-off between absolute accuracy and power dissipation; while rated at 250 mW, designers must carefully manage thermal management to prevent exceeding this limit and compromising the tight 0.1% tolerance, especially in compact, high-density PCBs.
