GS4A022211CT Description

The GS4A022211CT from TT Electronics/IRC is a high-precision 4-resistor isolated network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC ceramic package, it features 2.21KΩ thin-film resistors with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range (70°C to 125°C). The isolated circuit design (ISOL) allows independent resistor operation, while the 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating make it suitable for precision analog and signal conditioning circuits.

GS4A022211CT Features

• Ceramic SOIC-C Series: Robust construction with rectangular ceramic case for enhanced thermal performance.
• High Precision: ±0.25% absolute tolerance and ±50ppm/°C TCR for critical applications.
• Isolated Resistors: Independent elements reduce crosstalk in multi-channel systems.
• Surface-Mount Gull Wing Terminals: 1.27mm pitch for easy PCB integration.
• Wide Temperature Range: Derated power operation up to 125°C, ideal for industrial environments.
• Compact Dimensions: 4.9mm (L) x 5.99mm (D) x 1.45mm (H) with tight tolerances (±0.1mm height/length).

GS4A022211CT Applications

This resistor network excels in:

• Precision voltage dividers and analog signal conditioning in test/measurement equipment.
• Isolated feedback networks for op-amps and ADCs/DACs.
• Medical devices requiring stable, low-drift resistance.
• Industrial control systems where high-temperature operation is critical.
• Automotive-grade alternatives (though not PPAP/automotive-certified).

Conclusion of GS4A022211CT

The GS4A022211CT combines high accuracy, thermal resilience, and compact design, making it a superior choice for precision electronics. Its isolated thin-film resistors and ceramic package outperform plastic-encased networks in harsh environments. While not RoHS-compliant, it remains a reliable solution for military, aerospace, and industrial applications demanding uncompromising performance.
