GS4A026342FT

GS4A026342FT Description

The GS4A026342FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. Housed in an 8-pin narrow SOIC package, this device features four isolated thin-film resistors, each with a resistance value of 63.4 kΩ and a tight ±1% tolerance. The SOIC-C series construction ensures excellent reliability in demanding environments, with a maximum operating temperature of 125°C and a derated power range of 70°C to 125°C. Its ±50 ppm/°C temperature coefficient guarantees minimal resistance drift, making it ideal for precision analog and digital circuits.

GS4A026342FT Features

• High Precision: ±1% absolute tolerance and ±50 ppm/°C TCR ensure stable performance.
• Robust Construction: Ceramic substrate and gull-wing termination enhance durability and solderability.
• Isolated Resistors: Four independent resistors (63.4 kΩ each) prevent crosstalk in multi-channel designs.
• Surface-Mount Design: SOIC package (4.9 mm × 5.99 mm × 1.45 mm) with 1.27 mm terminal pitch for compact PCB layouts.
• Wide Voltage Range: Supports up to 100 V, suitable for industrial and instrumentation applications.
• Power Handling: 0.1 W per resistor (0.4 W total) with derating up to 125°C.

GS4A026342FT Applications
