GS4A021182DAT

GS4A021182DAT Description

The GS4A021182DAT 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 resistance value of 11.8 kΩ and an absolute tolerance of ±0.5%. Its ±50 ppm/°C temperature coefficient ensures stable performance across a wide operating range of 70°C to 125°C. The network is housed in a rectangular SOIC package with gull-wing terminations, offering excellent thermal and mechanical stability. With a maximum voltage rating of 100V and a power rating of 0.4W (0.1W per resistor), this component is ideal for precision analog and digital circuits.

GS4A021182DAT Features

• High Precision: ±0.5% absolute tolerance and ±0.05% ratio tolerance for critical applications.
• Robust Construction: Ceramic case ensures durability and thermal stability.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Low TCR: ±50 ppm/°C minimizes resistance drift under thermal stress.
• Surface-Mount Design: SOIC package (4.9mm x 5.99mm x 1.45mm) with 1.27mm terminal pitch for compact PCB layouts.
• Isolated Resistors: Independent elements reduce crosstalk in multi-channel systems.

GS4A021182DAT Applications

This resistor network excels in:

• Precision voltage dividers in measurement equipment.
• Signal conditioning circuits for sensors and ADCs.
• Industrial control systems requiring stable resistance ratios.
• Medical electronics where low drift and high accuracy are critical.
• Automotive test systems (though not qualified for in-vehicle use).

Conclusion of GS4A021182DAT

The GS4A021182DAT stands out for its exceptional accuracy, thermal stability, and compact form factor, making it a top choice for engineers designing high-reliability circuits. Its ceramic construction and thin-film technology provide superior performance over standard thick-film networks, particularly in environments with fluctuating temperatures. While not PPAP or automotive-qualified, it is well-suited for industrial, medical, and test/measurement applications where precision is paramount.
