GS4A039761FBT Description

The GS4A039761FBT from TT Electronics/IRC is a high-precision 4-resistor isolated network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC ceramic package, it features 9.76KΩ thin-film resistors with an absolute tolerance of ±1% and a ratio tolerance of ±0.1%, ensuring exceptional accuracy. The device operates over a wide temperature range (70°C to 125°C) with a low ±25ppm/°C temperature coefficient, making it ideal for stable performance in varying environmental conditions. With a 0.1W power rating per resistor (0.4W total) and a 100V maximum voltage rating, it combines reliability with compact surface-mount (SOIC) packaging (4.9mm x 5.99mm x 1.45mm).

GS4A039761FBT Features

• Precision Performance: Thin-film technology delivers ±1% tolerance and ±0.1% ratio tolerance for critical analog circuits.
• Robust Construction: Ceramic case ensures durability and thermal stability, with a 125°C maximum operating temperature.
