GS4B022870GGT

GS4B022870GGT Description

The GS4B022870GGT 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 287Ω resistance per element with a tight ±2% absolute tolerance and ±2% ratio tolerance. Its ±50ppm/°C temperature coefficient ensures stable performance across a wide operating temperature range of -55°C to +125°C, with derated power handling up to 125°C. The 8-pin gull-wing termination facilitates reliable surface-mount assembly, while the 0.05W (1/20W) power rating per resistor and 0.4W total power rating make it suitable for low-power, high-density designs.

GS4B022870GGT Features

• Ceramic SOIC Package: Robust rectangular ceramic case (4.9mm x 5.99mm x 1.45mm) with ±0.1mm length/height tolerances for precise PCB integration.
• Bussed Network Architecture: Simplifies circuit design by interconnecting resistors via a common bus, reducing component count.
• Thin-Film Technology: Delivers low noise, high stability, and tight tolerances (±2%) for critical analog/digital signal conditioning.
• Wide Voltage Range: Supports up to 100V maximum voltage, ideal for industrial and instrumentation applications.
• Automotive-Grade Alternatives: While this variant is not PPAP or automotive-qualified, its 125°C rating suits harsh environments.

GS4B022870GGT Applications

• Signal Conditioning: Precision voltage dividers, ADC/DAC reference networks.
• Industrial Controls: PLCs, sensor interfaces, and power management circuits.
• Test & Measurement Equipment: High-accuracy instrumentation requiring stable resistance ratios.
• Consumer Electronics: Audio equipment, display drivers, and low-power logic circuits.
• Aerospace & Defense: Non-RoHS version (EU non-compliant) may be used in exempted legacy systems.

Conclusion of GS4B022870GGT

The GS4B022870GGT excels in space-constrained, precision applications where thermal stability, low tolerance drift, and compact form factor are critical. Its ceramic construction and thin-film technology provide superior reliability over polymer-based networks, while the bussed design streamlines PCB layout. Though not automotive-certified, its 125°C operational range and 100V rating make it a versatile choice for industrial, medical, and high-reliability electronics. Engineers should verify unconfirmed part status with TT Electronics/IRC for production use.
