GS7A011472GT

GS7A011472GT Description

The GS7A011472GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values across varying temperatures. Housed in a 14-pin narrow SOIC package, this device features 7 isolated thin-film resistors, each with a 14.7KΩ resistance and a tight ±2% tolerance. Its ±100ppm/°C temperature coefficient ensures minimal resistance drift, making it suitable for environments with fluctuating thermal conditions. The network operates within a 70°C to 125°C derated power range, with a maximum voltage rating of 100V and a 0.1W power rating per resistor (0.7W total). The gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances durability and heat dissipation.

GS7A011472GT Features

• Isolated Circuit Design: Each of the 7 resistors is electrically isolated, enabling independent operation and flexibility in circuit design.
• High Stability: Thin-film technology and ±100ppm/°C TCR deliver consistent performance under thermal stress.
• Robust Construction: Ceramic SOIC package ensures mechanical strength and reliability in harsh environments.
• Precision Tolerance: ±2% absolute tolerance and ±0.1mm dimensional tolerances for precise PCB alignment.
• Wide Operating Range: Supports -55°C to 125°C, with derated power up to 125°C.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, TT Electronics offers compliant variants for automotive applications.

GS7A011472GT Applications

• Signal Conditioning: Ideal for op-amp feedback networks, voltage dividers, and DAC/ADC interfaces due to low drift.
