GS4B012102CT

GS4B012102CT Description

The GS4B012102CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC (SOIC-C Series) device integrates 7 bussed resistors with a 21KΩ resistance value and an ultra-tight ±0.25% tolerance, ensuring exceptional accuracy. Built with thin-film technology, it offers a ±100ppm/°C temperature coefficient, stable performance across a wide temperature range (70°C to 125°C), and a maximum operating temperature of 125°C. The 0.05W (1/20) power rating per resistor and 0.4W total power rating make it suitable for low-power circuits, while its 100V maximum voltage rating enhances reliability in high-voltage environments.

GS4B012102CT Features

• Precision & Stability: ±0.25% absolute tolerance and ±100ppm/°C TCR ensure minimal drift.
• Robust Construction: Ceramic case with gull-wing termination for durability and easy surface-mount (SMD) assembly.
• Compact Design: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Bussed Network: Simplified PCB layout with 7 resistors connected to a common bus, reducing component count.
• Wide Operating Range: Derated power up to 125°C, ideal for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
