CRGH2512J390K – TE CONNECTIVITY

Overview

The TE Connectivity CRGH2512J390K is a high-power thick-film surface-mount resistor designed for robust current handling in demanding electronic circuits. Its 2W power dissipation capability, coupled with a 390 kΩ resistance value and a ±5% tolerance, makes it suitable for power limiting and voltage division applications. A critical design consideration for such components is managing thermal runaway; while rated for 2W, designers must ensure adequate PCB copper area and airflow to maintain junction temperatures well below the +125°C maximum, especially during transient overloads, to preserve long-term reliability and prevent premature failure.
