GS4B022151CAT Description

The GS4B022151CAT from TT Electronics/IRC is a high-precision 7-resistor bussed network in an 8-pin narrow SOIC (SOIC-C) ceramic package, designed for demanding surface-mount applications. This thin-film resistor network offers a 2.15KΩ resistance per element with an exceptional ±0.25% absolute tolerance and ±0.05% ratio tolerance, ensuring superior accuracy in signal conditioning and voltage division circuits. Its ±50ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for stable performance across industrial and automotive environments (though not PPAP or Automotive qualified). The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating provide robust handling for analog and mixed-signal systems.

GS4B022151CAT Features

• Precision Thin Film Technology: Delivers low TCR (±50ppm/°C) and tight tolerances (±0.25%) for critical analog applications.
• Ceramic SOIC Package: Enhances thermal stability and mechanical durability compared to polymer-based networks.
• Bussed Network Design: Simplifies PCB layout with shared connections (BUS circuit designator).
• High Power Density: 0.4W total dissipation in a compact 4.9mm × 5.99mm × 1.45mm footprint.
• Gull Wing Termination: Ensures reliable surface-mount soldering with a 1.27mm terminal pitch.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for harsh environments.

GS4B022151CAT Applications
