GS4A021242GFT Description

The GS4A021242GFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in an 8-pin narrow SOIC (SOIC-C) package, it features four isolated thin-film resistors, each with a resistance value of 12.4 kΩ and a tight ±2% absolute tolerance (±1% ratio tolerance). The device operates over a wide temperature range of -70°C to +125°C, with a ±50 ppm/°C temperature coefficient, ensuring stability in demanding environments. Its 0.1W (1/10W) power rating per resistor and 100V maximum voltage rating make it suitable for low-power, high-voltage circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration.

GS4A021242GFT Features

• Isolated Resistors: Four independent resistors in a single package, reducing board space and improving signal integrity.
• High Precision: ±2% absolute tolerance and ±1% ratio tolerance for accurate voltage division and signal conditioning.
• Robust Construction: Ceramic case and thin-film technology ensure reliability under thermal stress.
• Wide Operating Range: -70°C to +125°C with derated power up to 125°C, ideal for industrial and automotive environments (though not PPAP/automotive-qualified).
• Compact & Standardized: SOIC package (4.9mm x 5.99mm x 1.45mm) with 1.27mm terminal pitch, compatible with automated assembly.
• Low TCR: ±50 ppm/°C minimizes resistance drift over temperature.
