GS4B011780JDT Description

The GS4B011780JDT from TT Electronics/IRC is a high-performance 7-resistor bussed network in a narrow SOIC (Small Outline Integrated Circuit) package, designed for precision applications requiring stable resistance values under varying thermal conditions. Encased in a ceramic substrate, this thin-film resistor network offers a 178Ω resistance per element with a ±5% absolute tolerance and ±0.5% ratio tolerance, ensuring consistent performance in matched-resistance circuits. Its ±100ppm/°C temperature coefficient and 125°C maximum operating temperature make it suitable for environments with moderate thermal stress. The 8-pin gull-wing termination facilitates reliable surface-mount (SMD) assembly, while the 0.05W (1/20W) power rating per resistor and 100V maximum voltage rating cater to low-power signal conditioning and voltage division tasks.

GS4B011780JDT Features

• Ceramic Construction: Enhances thermal stability and durability in harsh environments.
• Bussed Network Design: Simplifies PCB layout by connecting resistors in a common-bus configuration (Circuit Designator: BUS).
• Precision Thin Film Technology: Delivers low noise and tight tolerance (±5% absolute, ±0.5% ratio).
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, ideal for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Compact SOIC Package: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) dimensions with ±0.1mm height/length tolerances ensure space-efficient mounting.
• High Voltage Handling: 100V rating supports robust signal isolation.

GS4B011780JDT Applications

• Industrial Controls: PLCs, sensor interfaces requiring stable resistance ratios.
• Consumer Electronics: Audio equipment, display drivers leveraging its low TCR (Temperature Coefficient of Resistance).
• Test & Measurement: Precision calibration circuits due to tight ratio tolerance.
• Power Management: Low-current feedback networks in DC-DC converters.

Conclusion of GS4B011780JDT

The GS4B011780JDT excels in applications demanding compact size, thermal resilience, and matched resistance values. Its ceramic SOIC package and thin-film technology provide superior performance over polymer-based networks, while the bussed architecture reduces design complexity. Though not RoHS-compliant or automotive-grade, it remains a cost-effective solution for industrial and consumer electronics where precision and reliability are paramount. Engineers will appreciate its balance of power efficiency (0.4W total rating), voltage tolerance, and mechanical robustness in space-constrained designs.
