GS7B033831JDT Description

The GS7B033831JDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values under varying thermal conditions. Packaged in a 14-pin narrow SOIC (SOIC-C series), this bussed network integrates 13 thin-film resistors, each rated at 3.83KΩ ±5% absolute tolerance and ±0.5% ratio tolerance, ensuring consistent performance in matched-resistor applications. With a ±25ppm/°C temperature coefficient, it delivers exceptional thermal stability across an operating range of 70°C to 125°C. The device features a 0.7W total power rating (0.05W per resistor) and supports 100V maximum voltage, making it suitable for moderate-power circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the ceramic case enhances durability and heat dissipation.

GS7B033831JDT Features

• Precision Thin-Film Technology: Delivers low TCR (±25ppm/°C) and tight tolerance (±5% absolute, ±0.5% ratio) for high-accuracy applications.
• Robust Ceramic Package: SOIC-C case style ensures mechanical strength and thermal performance in harsh environments.
• Bussed Network Design: Simplifies circuit layout with 13 resistors sharing a common bus connection (BUS designator).
• Surface-Mount Compatibility: Gull-wing terminals and 1.27mm pitch enable efficient automated assembly.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power handling.
• Compact Dimensions: 8.66mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).

GS7B033831JDT Applications

Ideal for precision analog circuits, voltage dividers, and sensor signal conditioning where matched resistances are critical. Its stability and low TCR make it suitable for:

• Industrial Control Systems: Feedback networks in PID controllers.
• Automotive Electronics (non-AECQ): Sensor interfaces and legacy ECU designs.
• Test & Measurement Equipment: Calibration circuits and reference networks.
• Medical Devices: Signal processing in diagnostic equipment (where RoHS compliance is not mandated).
