GS4B022100JGT

GS4B022100JGT Description

The GS4B022100JGT 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 resistance values under varying thermal conditions. Built with thin-film technology on a ceramic substrate, it offers a 210Ω resistance per element with an absolute tolerance of ±5% and a ratio tolerance of ±2%. The device operates within a temperature range of -55°C to +125°C, featuring a low temperature coefficient of ±50ppm/°C for minimal drift. Its 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for moderate-power circuits. The gull-wing termination ensures reliable surface-mount assembly, while the compact SOIC-C case (4.9mm x 5.99mm x 1.45mm) saves board space.

GS4B022100JGT Features

• Bussed Network Topology: Simplifies PCB layout by connecting resistors in a common-bus configuration.
• Ceramic Substrate: Enhances thermal stability and durability in harsh environments.
• Low TCR (±50ppm/°C): Ensures consistent performance across temperature fluctuations.
• High Voltage Tolerance (100V): Ideal for industrial and automotive signal conditioning.
• Precision Tolerance: ±5% absolute and ±2% ratio tolerance for matched resistance values.
• RoHS Non-Compliant: Suitable for legacy systems where lead-free alternatives are incompatible.

GS4B022100JGT Applications

This resistor network excels in:

• Voltage Divider Circuits: Precision attenuation in sensor interfaces or ADC front-ends.
• Bus Termination: Damping signal reflections in high-speed digital lines (e.g., CAN, SPI).
• Industrial Control Systems: Stable biasing and pull-up/down networks in PLCs.
• Legacy Electronics Repair: Direct replacement for non-RoHS compliant designs.
• Power Supply Feedback Loops: Low-drift feedback networks in DC-DC converters.

Conclusion of GS4B022100JGT

The GS4B022100JGT combines thin-film precision, ceramic robustness, and bussed convenience for demanding analog and mixed-signal designs. Its tight tolerance, low TCR, and compact SOIC footprint make it a superior choice over generic thick-film networks, particularly in environments requiring thermal stability or moderate voltage handling. While not automotive-grade, it is well-suited for industrial, telecom, and legacy systems where reliability and space efficiency are critical.
