GS7A011271JBT Description

The GS7A011271JBT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. This 14-pin narrow SOIC package features 7 isolated thin-film resistors, each with a 1.27KΩ resistance and a ±5% absolute tolerance, ensuring reliable performance in demanding environments. With a ±100ppm/°C temperature coefficient, it maintains consistent operation across a 70°C to 125°C derated power range, making it suitable for thermally sensitive circuits. The SOIC-C series construction offers robust surface-mount compatibility, while its 100V maximum voltage rating and 0.1W power rating per resistor (0.7W total) ensure durability in compact designs.

GS7A011271JBT Features

• Isolated Circuit Design: Each of the 7 resistors operates independently, minimizing crosstalk.
• Precision Thin-Film Technology: Delivers ±0.1% ratio tolerance for matched resistance pairs.
• Wide Temperature Range: Stable performance from -55°C to 125°C (operational), derated up to 125°C.
• Compact & Robust: SOIC package (8.66mm x 5.99mm x 1.45mm) with gull-wing terminals for secure PCB mounting.
• High Voltage Tolerance: Supports up to 100V, ideal for industrial and automotive-grade applications.
• Ceramic Substrate: Enhances thermal dissipation and mechanical stability.
