GS8B034221FAT

GS8B034221FAT Description

The GS8B034221FAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 16-pin narrow SOIC device features 15 bussed resistors with a 4.22KΩ resistance value and an absolute tolerance of ±1%, ensuring consistent performance. Built with thin-film technology, it offers a low temperature coefficient of ±25ppm/°C, making it stable across a wide operating temperature range of -70°C to +125°C. The SOIC package (9.91mm x 5.99mm x 1.45mm) with gull-wing terminations facilitates easy surface-mount assembly, while its 0.05W (1/20) power rating per resistor and 100V maximum voltage rating ensure reliability in compact designs.

GS8B034221FAT Features

• Bussed Network Configuration: Simplifies circuit design by connecting multiple resistors to a common bus.
• High Precision: ±1% absolute tolerance and ±0.05% ratio tolerance for critical analog/digital applications.
• Robust Construction: Ceramic case ensures durability and thermal stability.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power.
• Low TCR: ±25ppm/°C minimizes resistance drift under thermal stress.
• Surface-Mount Ready: Gull-wing terminals and 1.27mm pitch for automated PCB assembly.
• Compact Footprint: SOIC package saves board space without compromising performance.

GS8B034221FAT Applications

This resistor network is ideal for:

• Precision Voltage Dividers: In ADCs, DACs, and sensor interfaces where ratio tolerance is critical.
