GS4A033090FBT

GS4A033090FBT Description

The GS4A033090FBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 4-resistor isolated network features a 309Ω resistance value with a tight ±1% absolute tolerance and ±0.1% ratio tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. Housed in an 8-pin narrow SOIC package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with gull-wing termination for reliable surface-mount assembly. The thin-film technology delivers ±25ppm/°C temperature coefficient, stable performance across -70°C to +125°C, and a 100V maximum voltage rating. Its 0.1W power rating per resistor (0.4W total) and ceramic case provide robust thermal management, though it is non-compliant with EU RoHS.

GS4A033090FBT Features

• Precision Network: 4 isolated resistors with ±1% tolerance and ±0.1% ratio tolerance for matched performance.
• Stable Thin-Film Construction: ±25ppm/°C TCR ensures minimal resistance drift over temperature.
• High-Density SOIC Package: 8-pin narrow SOIC (4.9mm × 5.99mm) saves PCB space while enabling automated placement.
