GS4A021782GAT

GS4A021782GAT Description

The GS4A021782GAT 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 17.8KΩ and a tight ±2% absolute tolerance. Its ±50ppm/°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 is optimized for surface-mount assembly, offering robust mechanical and thermal reliability.

GS4A021782GAT Features

• Isolated Resistors: Four independent resistors (17.8KΩ each) for flexible circuit design.
• High Precision: ±2% tolerance and ±0.05% ratio tolerance for critical analog/digital applications.
• Wide Temperature Range: Stable performance from -70°C to +125°C with derated power up to 125°C.
• Robust Construction: Ceramic substrate and thin-film technology for low noise and high reliability.
• Surface-Mount Ready: SOIC package (1.27mm pitch) with gull-wing leads for automated PCB assembly.
• Power Handling: 0.1W per resistor (0.4W total) and 100V maximum voltage rating.

GS4A021782GAT Applications

• Precision Voltage Dividers: Ideal for sensor interfaces and ADC/DAC circuits due to low ratio tolerance.
• Industrial Electronics: Suitable for harsh environments (e.g., motor control, power supplies) with its wide temperature range.
• Medical Devices: Reliable performance in diagnostic equipment where stability is critical.
• Automotive Systems: Despite not being PPAP/automotive-qualified, it suits non-safety-critical automotive electronics.
• Test & Measurement: High accuracy makes it fit for calibration tools and instrumentation.

Conclusion of GS4A021782GAT

The GS4A021782GAT excels in precision and durability, leveraging ceramic thin-film technology for applications demanding tight tolerances and thermal stability.
