GS4B038661DAT Description

The GS4B038661DAT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor BUS-configuration array offers a 8.66KΩ resistance value with an ultra-tight ±0.5% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of -70°C to +125°C. Housed in a ceramic SOIC-8 package, it features gull-wing SMD terminations for reliable surface-mount assembly. With a 0.4W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is engineered for precision analog and digital circuits where accuracy and thermal performance are critical.

GS4B038661DAT Features

• High Precision: ±0.5% tolerance and ±25ppm/°C TCR for stable performance in varying conditions.
• Robust Construction: Ceramic substrate and thin-film technology ensure durability and long-term reliability.
• Compact Design: 4.9mm x 5.99mm footprint with a low 1.45mm profile, ideal for space-constrained PCBs.
• Automotive-Grade Alternatives: While not PPAP or Automotive-qualified, its 125°C max operating temp suits industrial and telecom applications.
• Optimized Power Handling: 0.4W total dissipation (distributed across 7 resistors) mitigates thermal stress.
• Strict Dimensional Tolerances: ±0.1mm (L/W) and ±0.2mm (D) for consistent manufacturability.
