GS4B022321BBT Description

The GS4B022321BBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. It features 7 resistors in a BUS configuration, each with a 2.32KΩ resistance value and an ultra-tight 0.1% tolerance. Encased in a ceramic SOIC package, this 8-pin surface-mount device (SMD) offers excellent thermal stability with a ±50ppm/°C temperature coefficient. The network operates over a wide temperature range (70°C to 125°C) and delivers a total power rating of 0.4W (0.05W per resistor). Its gull-wing termination ensures reliable PCB mounting, while the 100V maximum voltage rating makes it suitable for high-voltage circuits.

GS4B022321BBT Features

• Precision Performance: 0.1% tolerance and ±50ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case and thin-film technology provide superior durability and long-term stability.
• Compact Design: 4.9mm × 5.99mm × 1.45mm dimensions with ±0.1mm length/height tolerances enable high-density PCB layouts.
• High Power Handling: 0.4W total dissipation (0.05W per resistor) supports energy-efficient designs.
• Automated Assembly Friendly: Gull-wing leads and 1.27mm pitch simplify pick-and-place processes.
• Wide Operating Range: -70°C to +125°C derated power capability ensures reliability in harsh environments.
