GS4B034121GDT Description

The GS4B034121GDT 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 4.12KΩ resistance per element with a tight ±2% absolute tolerance and ±0.5% ratio tolerance, ensuring exceptional accuracy in voltage division and signal conditioning circuits. Its ±25ppm/°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 of moderate power loads.

GS4B034121GDT Features

• Ceramic SOIC Package: Enhances thermal stability and durability in harsh conditions.
• Bussed Network Design: Simplifies PCB layout for common-bus applications like pull-up/pull-down arrays.
• Precision Thin Film: Delivers low noise and high stability (±25ppm/°C) for precision analog circuits.
• Gull Wing Termination: Ensures reliable surface-mount soldering with a 1.27mm terminal pitch.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length).
• Non-RoHS Compliant: Suitable for legacy or niche applications requiring non-compliant materials.
