GS4B021690JT

GS4B021690JT Description

The GS4B021690JT from TT Electronics/IRC is a high-performance 7-resistor bussed network designed for precision applications in demanding electronic circuits. Encased in a narrow SOIC (SOIC-C) ceramic package, this thin-film resistor network offers a 169Ω resistance per element with a tight ±5% tolerance and a low ±50ppm/°C temperature coefficient. Its 8-pin gull-wing termination ensures reliable surface-mount compatibility, while the 0.05W (1/20) power rating per resistor and 0.4W total power handling make it suitable for low-power signal conditioning. The device operates across a wide temperature range (-70°C to +125°C), with a 100V maximum voltage rating, and is housed in a compact 4.9mm × 5.99mm × 1.45mm footprint.

GS4B021690JT Features

• Robust Construction: Ceramic substrate and thin-film technology ensure stability and durability in harsh environments.
• Precision Performance: ±5% absolute tolerance and ±50ppm/°C TCR for consistent signal integrity.
• Space-Efficient Design: Narrow SOIC package (8-pin) with a 1.27mm terminal pitch optimizes PCB real estate.
• Bussed Topology: Simplifies circuit design by connecting resistors in a shared bus configuration (BUS designator).
• High-Temperature Operation: Rated for 125°C maximum operating temperature, ideal for industrial and automotive-adjacent applications (though not PPAP/automotive-certified).
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.

GS4B021690JT Applications

This resistor network excels in:

• Signal Conditioning: Voltage division, pull-up/pull-down networks in analog/digital hybrid circuits.
• Industrial Controls: PLCs, sensor interfaces, and instrumentation requiring stable resistance under thermal stress.
• Telecommunications: Impedance matching and termination in RF/module designs.
• Legacy Systems: Maintenance or upgrades for non-RoHS-compliant assemblies.
• Power Management: Low-power feedback networks in DC-DC converters or LED drivers.

Conclusion of GS4B021690JT

The GS4B021690JT combines precision, compactness, and reliability, making it a standout choice for engineers needing a bussed resistor network with robust thermal performance. Its ceramic SOIC package and thin-film technology offer superior stability over polymer-based alternatives, while the non-RoHS compliance ensures compatibility with specialized industrial systems. Ideal for space-constrained, high-temperature environments, this network balances cost-effectiveness with technical rigor for mid-tier precision applications.
