GS4A031213GFT

GS4A031213GFT Description

The GS4A031213GFT from TT Electronics/IRC is a high-precision 4-resistor network in an 8-pin narrow SOIC package, designed for isolated (ISOL) circuit applications. This ceramic-based, thin-film resistor network offers a 121KΩ resistance per element with a tight ±2% absolute tolerance and ±1% ratio tolerance, ensuring superior matching accuracy. Operating within a -70°C to +125°C temperature range, it delivers stable performance with a low ±25ppm/°C temperature coefficient. The SOIC-C series construction features gull-wing terminations for reliable surface-mount (SMD) assembly, with a compact footprint of 4.9mm (L) × 5.99mm (D) × 1.45mm (H) and a 1.27mm terminal pitch. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it is ideal for precision analog and signal conditioning circuits.
