GS7A011240JDT Description

The GS7A011240JDT by 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 resistance value of 124Ω and an absolute tolerance of ±5%. The device operates within a temperature range of 70°C to 125°C, with a ±100ppm/°C temperature coefficient, ensuring minimal resistance drift. Its SOIC-C series construction offers robust surface-mount compatibility, with gull-wing termination for reliable PCB connections. The 0.1W power rating per resistor (0.7W total) and 100V maximum voltage rating make it suitable for moderate-power circuits.

GS7A011240JDT Features

• Isolated Circuit Design: Each of the 7 resistors is electrically isolated, enabling independent operation in multi-channel applications.
• Precision Thin-Film Technology: Delivers ±5% tolerance and ±0.5% ratio tolerance for matched resistance pairs.
• Wide Temperature Range: Stable performance from 70°C to 125°C with derated power handling.
• Compact & Robust: Ceramic case with 8.66mm × 5.99mm × 1.45mm dimensions (±0.1mm tolerance) and 1.27mm terminal pitch for high-density layouts.
• Surface-Mount Ready: Gull-wing leads and SOIC package simplify automated assembly processes.
• Non-Automotive Grade: Ideal for industrial and commercial applications where PPAP compliance is not required.
