GS4A031913GGT Description

The GS4A031913GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 191 kΩ and a tight tolerance of ±2%. Its ±25 ppm/°C temperature coefficient ensures minimal resistance drift across the operating range of -70°C to +125°C, making it suitable for environments with significant thermal fluctuations. The SOIC-C series construction offers robust mechanical stability, with a compact footprint (4.9 mm × 5.99 mm × 1.45 mm) and gull-wing termination for reliable surface-mount assembly. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it balances precision with durability.

GS4A031913GGT Features

• Isolated Resistors: Four independent resistors (191 kΩ each) prevent crosstalk, ideal for signal isolation.
• High Stability: Thin-film technology and ±25 ppm/°C TCR ensure consistent performance in thermal stress.
• Precision Tolerance: ±2% absolute and ratio tolerance for applications demanding exact resistance matching.
• Robust Packaging: Ceramic SOIC case enhances thermal dissipation and mechanical strength.
• Wide Operating Range: Functions reliably from -70°C to +125°C, with derated power up to 125°C.
• Surface-Mount Ready: Gull-wing leads and 1.27 mm pitch simplify PCB integration.
