GS4A021202FAT

GS4A021202FAT Description

The GS4A021202FAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 12 kΩ resistance value and a tight ±1% absolute tolerance. Its ±50 ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. The SOIC package (4.9mm x 5.99mm x 1.45mm) with gull-wing terminations enables reliable surface-mount assembly, while the ceramic construction enhances durability and thermal stability. Rated for 100V maximum voltage and 0.1W power dissipation per resistor, it is ideal for precision analog and digital circuits.

GS4A021202FAT Features

• Isolated Resistors: Four independent 12 kΩ resistors with ±0.05% ratio tolerance for matched performance.
• High Stability: Thin-film technology and ±50 ppm/°C TCR ensure minimal drift under thermal stress.
• Robust Construction: Ceramic case and SOIC package offer mechanical strength and compatibility with automated PCB assembly.
• Precision Tolerance: ±1% absolute tolerance and tight ratio matching for critical signal conditioning.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• Surface-Mount Ready: Gull-wing leads (1.27mm pitch) facilitate high-density PCB layouts.

GS4A021202FAT Applications

• Analog Signal Processing: Precision voltage dividers, feedback networks, and gain-setting circuits.
• Industrial Electronics: Sensor interfaces, instrumentation amplifiers, and control systems requiring stable resistance.
• Medical Devices: Low-noise, high-reliability circuits where thermal stability is critical.
• Automotive (Non-Automotive Rated): Test and measurement equipment, though not PPAP-compliant for direct automotive use.
• Communication Systems: Impedance matching and filtering in RF and mixed-signal designs.

Conclusion of GS4A021202FAT

The GS4A021202FAT excels in applications demanding high precision, thermal stability, and compact form factors. Its isolated thin-film resistors, ceramic construction, and tight tolerances make it superior to standard resistor arrays in performance-critical designs. While not automotive-grade, it is well-suited for industrial, medical, and communication systems where reliability and accuracy are paramount. Engineers will benefit from its low TCR, excellent matching, and robust packaging in space-constrained, high-performance circuits.
