GS4A0145R3GGT

GS4A0145R3GGT Description

The GS4A0145R3GGT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance characteristics. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 45.3Ω and a tight ±2% absolute tolerance. The device operates over a wide temperature range of 70°C to 125°C with a derated power capability, ensuring reliability in demanding environments. Its ±100ppm/°C temperature coefficient minimizes resistance drift, making it suitable for circuits where thermal stability is critical. The SOIC-C series construction provides robust mechanical integrity, while the gull-wing termination facilitates easy surface-mount assembly.

GS4A0145R3GGT Features

• High Precision: ±2% tolerance and ±2% ratio tolerance ensure consistent performance in matched resistor applications.
• Robust Construction: Ceramic case and thin-film technology deliver superior durability and long-term stability.
• Thermal Performance: Operates up to 125°C with a derated power range, ideal for high-temperature environments.
• Isolated Design: Four independent resistors (isolated elements) prevent crosstalk, enhancing signal integrity.
• Compact Footprint: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) dimensions with tight tolerances (±0.1mm L/H, ±0.2mm D) enable high-density PCB layouts.
• Surface-Mount Ready: 1.27mm terminal pitch and gull-wing leads simplify automated assembly processes.
