RP73PF2A392KBTDF – TE CONNECTIVITY

Overview

The TE CONNECTIVITY RP73PF2A392KBTDF is a high-precision, surface-mount thin-film resistor designed for demanding circuit applications. Its critical operational characteristic lies in its exceptionally low 0.1% tolerance and a tight 25 PPM/°C temperature coefficient, ensuring stable resistance values across a wide operating range. A key design consideration for such precision components is managing self-heating; while rated at 250mW, designers must carefully evaluate power dissipation in high-density boards to prevent exceeding the 155°C maximum operating temperature and compromising long-term accuracy.
