GS4B0139R0JDT Description

The GS4B0139R0JDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in an 8-pin narrow SOIC package, designed for precision applications requiring stable thin-film technology. With a 39Ω resistance per element and a ±5% absolute tolerance, this ceramic-based network ensures reliable performance in demanding environments. Its ±100ppm/°C temperature coefficient and 0.05W (1/20) power rating per resistor (0.4W total) make it suitable for circuits operating at 70°C to 125°C derated power. The SOIC-C series construction features gull-wing terminations with a 1.27mm pitch, enabling seamless surface-mount integration.

GS4B0139R0JDT Features

• Bussed Network Design: Simplifies PCB layout by connecting resistors in a common bus configuration.
• Thin-Film Technology: Delivers superior stability and low noise compared to thick-film alternatives.
• High Voltage Rating: Supports up to 100V, ideal for industrial and automotive (non-AECQ) applications.
• Compact & Robust: 4.9mm × 5.99mm × 1.45mm dimensions with ±0.1mm length/height tolerances ensure space efficiency.
• Wide Operating Range: Functions reliably from -55°C to +125°C, with derated power up to 125°C.
• Non-RoHS Compliant: Suitable for legacy or specialized systems where lead-free compliance is not required.

GS4B0139R0JDT Applications

• Voltage Division & Pull-Up/Down Circuits: Optimized for bus line termination in communication interfaces (e.g., I2C, SPI).
• Industrial Control Systems: Stable performance in PLC modules, sensor interfaces, and power management PCBs.
• Test & Measurement Equipment: Precision resistance networks for calibration and signal conditioning.
• Legacy Electronics Repair: Compatible with older designs requiring non-RoHS components.

Conclusion of GS4B0139R0JDT

The GS4B0139R0JDT excels in applications demanding tight tolerance (±5%), thermal stability, and compact form factor. Its ceramic substrate and thin-film technology provide long-term reliability, while the bussed architecture reduces component count. Though not PPAP or automotive-grade, it’s a cost-effective solution for industrial, telecom, and instrumentation designs. Engineers will appreciate its balance of performance, durability, and ease of integration in high-density layouts.
