GS4B0137R4JDT Description

The GS4B0137R4JDT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications in demanding electronic circuits. This 7-resistor bussed network is housed in an 8-pin narrow SOIC package, offering a compact footprint with 4.9mm length, 5.99mm depth, and 1.45mm height. It features a 37.4Ω resistance per element with a ±5% absolute tolerance and ±0.5% ratio tolerance, ensuring consistent performance in matched-resistor applications. The thin-film technology provides excellent stability, with a ±100ppm/°C temperature coefficient and a power rating of 0.05W (1/20W) per resistor (0.4W total). Rated for 100V maximum voltage, it operates reliably across a 70°C to 125°C temperature range, making it suitable for industrial and automotive-adjacent environments (though not PPAP or Automotive qualified).

GS4B0137R4JDT Features

• Ceramic substrate for enhanced thermal and mechanical stability.
• Bussed (BUS) circuit design simplifies PCB layout in voltage-divider or pull-up/down networks.
• Gull-wing termination ensures robust surface-mount (SMD) compatibility.
• Low TCR (±100ppm/°C) minimizes resistance drift under thermal stress.
• Narrow SOIC (SOIC-C) package saves board space while maintaining high-density integration.
• Non-RoHS composition (Note: Not compliant with EU RoHS).
• 1.27mm terminal pitch facilitates automated assembly processes.

GS4B0137R4JDT Applications

Ideal for precision analog and digital circuits requiring matched resistances, such as:

• Voltage dividers in sensor interfaces or ADC/DAC circuits.
• Pull-up/pull-down networks in microcontroller I/O lines.
• Signal conditioning in industrial control systems.
• Power supply feedback loops where stability is critical.
• Test and measurement equipment demanding tight tolerance ratios.

Conclusion of GS4B0137R4JDT

The GS4B0137R4JDT combines thin-film accuracy, ceramic durability, and compact SOIC packaging to deliver reliable performance in space-constrained, thermally challenging designs. While not suited for automotive-grade applications, its ±0.5% ratio tolerance and bussed topology make it a cost-effective solution for precision networks in industrial, telecom, and instrumentation systems. Engineers will appreciate its balance of performance, density, and ease of integration compared to discrete resistors or less stable alternatives.
