GS4A023920FAT

GS4A023920FAT Description

The GS4A023920FAT 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 392Ω and a tight ±1% absolute tolerance (with ±0.05% ratio tolerance). Its SOIC package (4.9mm × 5.99mm × 1.45mm) ensures compact surface-mount integration, while the gull-wing termination facilitates reliable PCB connections. With a ±50ppm/°C temperature coefficient, it delivers stable performance across a wide operating range of -55°C to +125°C, derated up to 125°C. Rated for 100V maximum voltage and 0.1W per resistor (0.4W total), it combines robustness with precision.

GS4A023920FAT Features

• Isolated Resistors: Four independent 392Ω resistors with 1% tolerance for precise signal conditioning.
• High Stability: Thin-film technology and ±50ppm/°C TCR ensure minimal drift under thermal stress.
• Compact & Durable: Ceramic SOIC case (4.9mm × 5.99mm) with ±0.1mm dimensional tolerances for high-density layouts.
• Wide Voltage Range: Supports up to 100V, ideal for industrial and automotive-grade circuits (though not PPAP/automotive-certified).
• Reliable Termination: Gull-wing leads (1.27mm pitch) enhance solder joint integrity in SMT processes.

GS4A023920FAT Applications

• Signal Isolation: Ideal for ADC/DAC reference networks, sensor interfaces, and differential signal paths.
• Precision Dividers: Used in voltage dividers and gain-setting circuits due to low ratio tolerance (±0.05%).
• Industrial Electronics: Suits power supplies, test equipment, and control systems requiring stable resistance under thermal cycling.
• Telecom & Networking: Deployed in filter networks and impedance-matching applications.

Conclusion of GS4A023920FAT

The GS4A023920FAT excels in precision analog circuits where isolation, thermal stability, and compactness are critical. While not automotive-qualified, its ceramic construction, low TCR, and tight tolerances make it a superior choice over standard thick-film networks in demanding environments. Engineers will value its reliability in industrial, telecom, and instrumentation designs, particularly where space and performance are constrained.
