GS7B031501JFT Description

The GS7B031501JFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. Housed in a 14-pin narrow SOIC package, this bussed (BUS) configuration integrates 13 thin-film resistors, each with a 1.5KΩ resistance and a ±5% absolute tolerance. The device operates over a wide temperature range of 70°C to 125°C with a low temperature coefficient of ±25ppm/°C, ensuring stable performance under thermal stress. Its 0.05W (1/20) power rating per resistor and 0.7W total power rating make it suitable for low-power circuits, while the 100V maximum voltage rating adds versatility. The SOIC-C series construction features gull-wing terminations for reliable surface-mount (SMD) assembly, with tight dimensional tolerances (±0.1mm height, ±0.2mm depth).

GS7B031501JFT Features

• 13-resistor network in a bussed (BUS) topology, simplifying PCB layout.
• Thin-film technology for precision (±5% tolerance, ±1% ratio tolerance) and low TCR (±25ppm/°C).
• Robust ceramic case with SOIC package (8.66mm x 5.99mm x 1.45mm), ideal for high-density designs.
• Wide operating range: -55°C to +125°C (derated power up to 125°C).
• Gull-wing terminals (1.27mm pitch) for secure SMT soldering.
• Non-automotive (PPAP: No) but suited for industrial/consumer electronics.
• 100V voltage rating and 0.7W total dissipation for reliable operation.

GS7B031501JFT Applications

This resistor network excels in precision analog circuits, voltage dividers, and signal conditioning where stable resistance ratios are critical. Its low TCR and tight tolerance make it ideal for:

• Medical devices (e.g., sensor interfaces).
• Test/measurement equipment requiring minimal drift.
• Industrial control systems (PLC I/O modules).
• Consumer electronics (audio amplifiers, ADC/DAC circuits).
  The bussed design reduces component count in bus termination or pull-up/pull-down networks, while the ceramic substrate enhances thermal stability.

Conclusion of GS7B031501JFT

The GS7B031501JFT combines precision, compactness, and reliability, offering a cost-effective solution for applications demanding stable resistance networks. Its thin-film construction, low TCR, and SOIC packaging provide a competitive edge over thicker-film or less stable alternatives. While not RoHS-compliant, it remains a robust choice for non-regulated industrial and consumer designs. Engineers will appreciate its ease of integration and consistent performance in thermally challenging environments.
