GS4A031871DAT

GS4A031871DAT Description

The GS4A031871DAT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding electronic applications. Featuring 1.87KΩ resistance with an absolute tolerance of ±0.5% and a ratio tolerance of ±0.05%, this thin-film ceramic resistor network ensures exceptional accuracy and stability. Its ±25ppm/°C temperature coefficient and 0.1W power rating per resistor (0.4W total) make it suitable for precision circuits operating in 70°C to 125°C environments. The SOIC-C series construction offers robust performance with 100V maximum voltage rating, gull-wing termination, and surface-mount compatibility.

GS4A031871DAT Features

• High Precision: ±0.5% absolute tolerance and ±0.05% ratio tolerance for critical analog/digital applications.
• Stable Performance: Thin-film technology with ±25ppm/°C thermal drift ensures reliability.
• Robust Construction: Ceramic case (SOIC package) with 4.9mm × 5.99mm × 1.45mm dimensions (±0.1mm tolerance).
• Isolated Design: Four independent resistors (isolated elements) reduce crosstalk in signal conditioning.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C.
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its precision suits industrial and instrumentation use.

GS4A031871DAT Applications

• Precision Voltage Dividers: Ideal for ADC/DAC reference circuits due to low ratio tolerance.
• Medical Equipment: Stable performance in diagnostic devices and patient monitoring systems.
• Test & Measurement: High-accuracy signal conditioning in oscilloscopes and multimeters.
• Industrial Controls: Isolated resistors for PLCs and sensor interfaces where thermal stability is critical.
• Communications: RF and baseband signal processing requiring minimal drift.

Conclusion of GS4A031871DAT

The GS4A031871DAT excels in applications demanding tight tolerance, low thermal drift, and isolation. Its ceramic SOIC package and thin-film technology provide durability and precision, though it lacks automotive compliance. Engineers will value its 0.05% ratio tolerance for matched resistor networks in analog systems, making it a superior choice over standard arrays for high-accuracy designs.
