GS4B034122FAT

GS4B034122FAT Description

The GS4B034122FAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor array features a 41.2KΩ resistance value per resistor with a tight 1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of -70°C to +125°C. Housed in an 8-pin SOIC ceramic package, it offers 0.4W total power dissipation (0.05W per resistor) and a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while its compact dimensions (4.9mm x 5.99mm x 1.45mm) save board space.

GS4B034122FAT Features

• Precision Thin Film Technology: Delivers high accuracy (±1%) and low TCR (±25ppm/°C) for stable operation in varying environments.
• Robust Ceramic Package: Enhances thermal performance and durability compared to plastic alternatives.
• High-Density Integration: Combines 7 resistors in an 8-pin SOIC, reducing component count and PCB footprint.
• Wide Operating Range: Rated for -70°C to +125°C, ideal for industrial and automotive (non-PPAP) applications.
• Surface-Mount Gull Wing Terminals: Ensures reliable solder joints and compatibility with automated assembly processes.
• Non-RoHS Compliant: Suitable for legacy or specialized designs requiring non-compliant materials.

GS4B034122FAT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers, feedback networks, and sensor interfaces.
