GS4A021001FAT

GS4A021001FAT Description

The GS4A021001FAT 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 1KΩ resistance and an absolute tolerance of ±1%. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -70°C to +125°C. The network is housed in a rectangular ceramic SOIC package, offering excellent thermal stability and durability. With a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V, this component is ideal for precision analog and digital circuits.

GS4A021001FAT Features

• Isolated Resistors: Four independent 1KΩ resistors with ±1% tolerance and ±0.05% ratio tolerance for precise matching.
• High-Temperature Stability: ±50ppm/°C TCR ensures minimal resistance drift in harsh environments.
• Robust Construction: Ceramic case with gull-wing terminations for reliable surface-mount (SMD) assembly.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).
• Wide Operating Range: Derated power up to 125°C, making it suitable for industrial and automotive-grade applications (though not PPAP/automotive certified).
• Low-Power Efficiency: 0.1W per resistor minimizes heat dissipation in dense PCB layouts.

GS4A021001FAT Applications

• Precision Voltage Dividers: Ideal for ADC/DAC reference circuits due to low ratio tolerance (±0.05%).
• Signal Conditioning: Stable performance in sensor interfaces and instrumentation amplifiers.
• Industrial Controls: Reliable operation in PLCs, motor drives, and power management systems.
• Medical Electronics: Low drift and high accuracy suit patient monitoring equipment.
• Test & Measurement: Critical for calibration circuits where resistance stability is paramount.
