GS4A0364R9GT

GS4A0364R9GT Description

The GS4A0364R9GT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance and thermal reliability. This 4-resistor isolated network is housed in an 8-pin narrow SOIC (SOIC-C) package, featuring thin-film technology for enhanced accuracy and durability. With a resistance value of 64.9Ω and a tight ±2% tolerance, it ensures consistent performance in critical circuits. The device operates over a wide temperature range of -70°C to +125°C, with a ±25ppm/°C temperature coefficient, minimizing resistance drift under thermal stress. Its 100V maximum voltage rating and 0.1W power rating per resistor (0.4W total) make it suitable for moderate-power applications.

GS4A0364R9GT Features

• Isolated Circuit Design: Each of the 4 resistors is electrically isolated, enabling flexible circuit configurations.
• High Stability: Ceramic substrate and thin-film construction deliver superior thermal and long-term stability.
• Precision Tolerance: ±2% absolute tolerance and ±25ppm/°C TCR ensure minimal deviation in harsh environments.
• Robust Packaging: 8-pin SOIC with gull-wing termination for reliable surface-mount assembly (SMD).
• Wide Operating Range: Rated for -70°C to +125°C, ideal for industrial and automotive-grade applications (though not PPAP/automotive-certified).
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D) for space-constrained designs.
