GS4A021051GAT

GS4A021051GAT Description

The GS4A021051GAT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 1.05 kΩ resistance and a tight ±2% absolute tolerance. The network operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±50 ppm/°C, ensuring stable performance under thermal stress. Encased in a rectangular ceramic SOIC package, it offers excellent thermal and mechanical stability, with a power rating of 0.1W per resistor (0.4W total) and a maximum voltage rating of 100V. Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GS4A021051GAT Features

• Isolated Resistors: Four independent resistors with ±0.05% ratio tolerance, ideal for precision signal conditioning.
• High Stability: Ceramic case and thin-film technology ensure low drift and long-term reliability.
• Robust Construction: Withstands 125°C maximum operating temperature and derated power up to 70°C–125°C.
• Compact & Precise: 4.9mm × 5.99mm × 1.45mm dimensions (±0.1mm tolerance) with 1.27mm terminal pitch for high-density layouts.
• Non-Automotive: Suitable for industrial and commercial applications, though PPAP and RoHS non-compliant.
