GS4A031102DT Description

The GS4A031102DT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features 11 kΩ resistance with an ultra-tight ±0.5% tolerance and a low ±25 ppm/°C temperature coefficient. Its thin-film technology ensures stability and reliability, while the ceramic case provides excellent thermal and mechanical durability. With a power rating of 0.4W (0.1W per resistor) and a maximum operating temperature of 125°C, this component is engineered for precision signal conditioning, voltage division, and impedance matching in compact PCB layouts.

GS4A031102DT Features

• High Precision: ±0.5% absolute tolerance ensures accuracy in critical circuits.
• Low TCR: ±25 ppm/°C minimizes resistance drift across temperature fluctuations.
• Robust Construction: Ceramic substrate enhances thermal dissipation and mechanical strength.
• Isolated Resistors: Independent elements (non-bussed) for flexible circuit design.
• Surface-Mount Gull Wing Terminals: Facilitates automated assembly with a 1.27mm pitch.
• Wide Voltage Rating: Supports up to 100V, suitable for industrial and instrumentation use.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D).

GS4A031102DT Applications

Ideal for precision analog and mixed-signal systems, the GS4A031102DT excels in:

• Medical Devices: Patient monitoring equipment requiring stable signal paths.
