GS4A011203FFT

GS4A011203FFT Description

The GS4A011203FFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 120KΩ resistance and a tight ±1% absolute tolerance. Its SOIC package (4.9mm × 5.99mm × 1.45mm) ensures compact surface-mount integration, while the gull-wing termination facilitates robust PCB connections. With a ±100ppm/°C temperature coefficient, it maintains stability across a wide operating range of -55°C to +125°C, derated up to 125°C. The ceramic substrate enhances thermal and mechanical durability, making it suitable for demanding environments.

GS4A011203FFT Features

• Isolated Circuit Design: Four independent resistors (120KΩ each) prevent crosstalk, ideal for signal isolation.
• Precision Tolerance: ±1% absolute and ratio tolerance ensures consistent performance in matched networks.
• Robust Construction: Ceramic case and thin-film technology deliver high reliability and low noise.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and automotive-grade circuits (non-automotive PPAP).
• Thermal Stability: ±100ppm/°C TCR minimizes drift across temperature fluctuations.
• Compact Footprint: SOIC-8 package (1.27mm pitch) optimizes space in high-density PCBs.

GS4A011203FFT Applications
