GS4A031212GFT Description

The GS4A031212GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 4-resistor isolated network features a 12.1KΩ resistance per element with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring excellent matching characteristics. Encased in an 8-pin narrow SOIC (SOIC-C) package, it utilizes thin-film technology for superior stability and low noise. With a ±25ppm/°C temperature coefficient, it maintains consistent performance across a -70°C to +125°C operating range. The 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GS4A031212GFT Features

• Isolated Resistors: Four independent 12.1KΩ resistors with 2% tolerance for precise signal conditioning.
• High Stability: ±25ppm/°C TCR and thin-film construction ensure minimal drift over temperature.
• Robust Packaging: Ceramic SOIC-C case offers mechanical durability and thermal resilience.
• Space-Efficient: Compact 4.9mm × 5.99mm × 1.45mm footprint ideal for dense layouts.
• Wide Operating Range: Reliable performance from -70°C to +125°C, even at derated power.
