CRGH2512J12K – TE CONNECTIVITY

Overview

The TE Connectivity CRGH2512J12K is a high-power thick film surface-mount resistor designed for demanding applications where precise power dissipation is critical. Its 2W power rating and 12kΩ resistance value, coupled with a ±5% tolerance, make it suitable for robust current limiting and voltage division circuits. A key design consideration for such components is managing thermal runaway; while this resistor boasts a wide operating temperature range of -55°C to +125°C, engineers must ensure adequate PCB heatsinking and airflow to prevent exceeding its thermal limits, thereby maintaining long-term reliability and preventing parametric drift beyond its 100 PPM/°C temperature coefficient.
