GS7A0154R9JDT Description

The GS7A0154R9JDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Housed in a 14-pin narrow SOIC package, this 7-resistor isolated network offers a 54.9Ω resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±0.5%, ensuring consistent performance in matched circuits. Its thin-film technology and ±100ppm/°C temperature coefficient provide excellent stability across a wide operating range of -55°C to +125°C, making it suitable for demanding environments. The SOIC-C series construction features a rectangular ceramic case with gull-wing terminations, optimized for surface-mount assembly in compact PCB designs.

GS7A0154R9JDT Features

• High Power Handling: 0.1W per resistor (0.7W total) with derating up to 125°C, ensuring reliability in power-sensitive circuits.
• Precision Tolerance: Tight ±5% absolute and ±0.5% ratio tolerance for matched resistance in differential pairs or voltage dividers.
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical durability compared to polymer-based networks.
• Low TCR: ±100ppm/°C minimizes resistance drift across temperature fluctuations.
• Compact Footprint: 8.66mm × 5.99mm × 1.45mm dimensions with 1.27mm terminal pitch, ideal for high-density layouts.
• Isolated Elements: Independent resistors reduce crosstalk, suited for multi-channel signal conditioning.
