GS7B021912CT

GS7B021912CT Description

The GS7B021912CT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stability. Housed in a 14-pin narrow SOIC package, this bussed (BUS) configuration integrates 13 thin-film resistors, each rated at 19.1KΩ with an absolute tolerance of ±0.25%. The device operates over a wide temperature range (70°C to 125°C @ derated power) and features a ±50ppm/°C temperature coefficient, ensuring minimal resistance drift. With a 0.7W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it is engineered for reliability in precision circuits. The gull-wing termination and surface-mount design facilitate automated assembly, while the ceramic case enhances thermal and mechanical durability.

GS7B021912CT Features

• High Precision: ±0.25% tolerance and ±50ppm/°C TCR for stable performance.
• Robust Construction: Ceramic SOIC package with 1.45mm height and 5.99mm × 8.66mm footprint, compliant with tight PCB spacing requirements.
• Bussed Network: Simplifies circuit design by connecting multiple resistors to a common node.
• Thin-Film Technology: Delivers low noise and high accuracy compared to thick-film alternatives.
• Automation-Friendly: Gull-wing leads and 1.27mm terminal pitch ensure compatibility with pick-and-place systems.
• Wide Operating Range: Suitable for environments up to 125°C, with derated power handling at elevated temperatures.

GS7B021912CT Applications
