GS4A019090GBT

GS4A019090GBT Description

The GS4A019090GBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 909Ω and a tight ±2% absolute tolerance (with ±0.1% ratio tolerance). Its SOIC package (4.9mm × 5.99mm × 1.45mm) ensures compact surface-mount integration, while the gull-wing termination facilitates reliable PCB connections. With a power rating of 0.4W total (0.1W per resistor) and a maximum operating temperature of 125°C, this network is engineered for stability across a wide temperature range (70°C to 125°C @ derated power). The ±100ppm/°C temperature coefficient and 100V maximum voltage rating further enhance its suitability for demanding environments.

GS4A019090GBT Features

• Isolated Resistor Network: Four independent resistors in a single SOIC package, reducing board space and simplifying design.
• High Precision: ±2% absolute tolerance and ±0.1% ratio tolerance ensure consistent performance in matched circuits.
• Robust Construction: Ceramic substrate and thin-film technology provide excellent thermal stability and long-term reliability.
• Wide Operating Range: Functions reliably from -55°C to 125°C, with derated power up to 125°C.
• Surface-Mount Ready: Gull-wing terminals and 1.27mm pitch enable easy automated assembly.
• Low TCR: ±100ppm/°C minimizes resistance drift over temperature variations.

GS4A019090GBT Applications

• Precision Voltage Dividers: Ideal for sensor signal conditioning and ADC/DAC reference circuits due to tight ratio tolerance.
