GS4A031473GAT

GS4A031473GAT Description

The GS4A031473GAT 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 147 kΩ and a tight ±2% absolute tolerance. Its ±25 ppm/°C temperature coefficient ensures stability across a wide operating range of 70°C to 125°C, making it suitable for demanding environments. The SOIC package (4.9 mm × 5.99 mm × 1.45 mm) with gull-wing terminations enables reliable surface-mount assembly, while the 0.1 W power rating per resistor (0.4 W total) balances compactness with robust performance.

GS4A031473GAT Features

• Isolated Resistor Network: Four independent resistors in a single package, reducing board space and improving signal integrity.
• Precision Thin-Film Technology: Delivers ±25 ppm/°C thermal stability and ±0.05% ratio tolerance for critical analog circuits.
• High-Temperature Resilience: Rated for 125°C maximum operating temperature, ideal for automotive and industrial systems (though not PPAP/automotive-qualified).
• Compact SOIC-C Ceramic Package: Combines low profile (1.45 mm height) with mechanical durability.
• 100V Maximum Voltage Rating: Supports moderate-voltage applications like sensor interfaces or feedback networks.
• Non-RoHS Compliance: Suitable for legacy or exempted designs requiring leaded components.

GS4A031473GAT Applications

This resistor network excels in:

• Precision Voltage Dividers: Leveraging its ±0.05% ratio tolerance for ADC reference circuits or sensor conditioning.
• Isolated Signal Paths: Isolated resistors prevent crosstalk in multi-channel data acquisition systems.
• High-Temperature Electronics: Industrial controls, power management, or test equipment where thermal drift must be minimized.
• Space-Constrained PCBs: The SOIC footprint optimizes layout density in compact designs like medical devices or instrumentation.

Conclusion of GS4A031473GAT

The GS4A031473GAT stands out for its precision, thermal stability, and isolation in a ceramic SOIC package. While not automotive-grade, its thin-film technology and tight tolerances make it a robust choice for industrial, telecom, and test/measurement applications. Engineers will appreciate its balance of performance, reliability, and space efficiency, particularly in analog circuits demanding minimal drift and high accuracy. For legacy or exempted designs, its non-RoHS compliance adds flexibility in component selection.
