GS4A027320FBT

GS4A027320FBT Description

The GS4A027320FBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a resistance value of 732Ω and a tight ±1% absolute tolerance (with ±0.1% ratio tolerance). Its SOIC-C series construction ensures robust performance in demanding environments, with a temperature coefficient of ±50ppm/°C for stable operation across a -70°C to +125°C range. The 0.1W (1/10W) power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for low-power, high-reliability circuits.

GS4A027320FBT Features

• Isolated Resistor Network: Four independent resistors in an 8-pin SOIC package, ideal for signal isolation.
• Precision Thin-Film Technology: Delivers ±1% tolerance and ±50ppm/°C TCR for stable performance.
• Robust Ceramic Case: Provides excellent thermal and mechanical stability.
• Surface-Mount Gull Wing Terminals: Ensures reliable 1.27mm pitch PCB mounting.
• Wide Operating Range: Functions reliably from -70°C to +125°C (derated power up to 125°C).
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).

GS4A027320FBT Applications

This resistor network excels in precision analog and digital circuits, including:
