GUS-SS4A-03-1001-B Description

The GUS-SS4A-03-1001-B from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding applications requiring tight tolerances and stable performance. This 4-resistor isolated network features a 1KΩ resistance value per resistor with an exceptional 0.1% tolerance and a low ±25ppm/°C temperature coefficient, ensuring minimal drift across operating conditions. Encased in an 8-pin SOIC Gull Wing SMD package, it offers a compact footprint (4.9mm × 5.99mm × 1.45mm) with surface-mount compatibility for automated assembly. The 0.4W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits.

GUS-SS4A-03-1001-B Features

• High Precision: ±0.1% tolerance and ±25ppm/°C TCR for stable performance in temperature-varying environments.
• Robust Construction: Thin-film technology ensures low noise, high reliability, and long-term stability.
• Isolated Design (ISOL): Each resistor operates independently, ideal for signal isolation or differential circuits.
• Compact SOIC Package: Gull-wing termination (1.27mm pitch) enables easy soldering and PCB integration.
• Wide Operating Range: -70°C to +125°C derated power range, with a maximum operating temperature of 125°C.
• Non-Automotive/Non-PPAP: Optimized for industrial, medical, and instrumentation applications.
