GS4A036191JGT

GS4A036191JGT Description

The GS4A036191JGT from TT Electronics/IRC is a high-precision 4-resistor network designed for isolation (ISOL) applications. Housed in an 8-pin narrow SOIC package with a ceramic case style, it features thin-film technology for stable performance. Each resistor offers a 6.19KΩ value with a ±5% absolute tolerance and ±2% ratio tolerance, ensuring tight matching for critical circuits. The device operates over a wide temperature range (70°C to 125°C derated, 125°C max) with a low ±25ppm/°C temperature coefficient, minimizing drift in harsh environments. Its 100V maximum voltage rating and 0.4W total power dissipation (0.1W per resistor) make it suitable for demanding analog and digital systems.

GS4A036191JGT Features

• Isolated Resistor Network: Four independent resistors in an SOIC-8 package, ideal for signal isolation.
• High Stability: ±25ppm/°C TCR and ceramic substrate ensure reliability under thermal stress.
