GS4B032870CCT

GS4B032870CCT Description

The GS4B032870CCT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 7-resistor BUS-configuration array offers a 287Ω resistance per element with an ultra-tight ±0.25% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a ceramic SOIC-8 package with gull-wing SMD termination, it combines 0.4W total power dissipation (0.05W per resistor) with a 100V maximum voltage rating, making it suitable for precision analog and digital circuits. The rectangular ceramic construction enhances thermal stability, while the 1.27mm terminal pitch facilitates compact PCB layouts.

GS4B032870CCT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive signal conditioning.
• Ceramic SOIC Package: Provides superior heat dissipation and mechanical robustness compared to polymer-based arrays.
• BUS Configuration: Simplifies circuit design in multi-channel systems (e.g., voltage dividers, pull-up networks).
• Automotive-Grade Alternatives: While this model is not PPAP or automotive-qualified, its 125°C operating limit suits industrial and telecom applications.
• Strict Tolerances: ±0.1mm length/height tolerances ensure consistent mounting compatibility.

GS4B032870CCT Applications

Ideal for:

• Precision Instrumentation: ADC/DAC reference networks, sensor signal conditioning.
• Telecom Infrastructure: Line termination, impedance matching in high-frequency PCBs.
• Industrial Controls: PLC I/O modules, power supply feedback loops.
• Medical Devices: Low-drift circuits where thermal stability is critical.

Conclusion of GS4B032870CCT

The GS4B032870CCT excels in high-reliability environments requiring tight resistance matching and thermal endurance. Its ceramic thin-film construction, combined with low TCR and high power density, offers a competitive edge over standard thick-film networks. While not RoHS-compliant, it remains a robust choice for non-consumer applications demanding precision and durability. Engineers should evaluate its derating requirements above 70°C to maximize longevity.
