GS4B037500GAT

GS4B037500GAT Description

The GS4B037500GAT from TT Electronics/IRC is a high-precision 7-resistor thin film network designed for surface-mount applications. Encased in a ceramic SOIC-8 package, it offers a 750Ω resistance per element with a tight 2% tolerance and a low ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The 0.4W total power rating (0.05W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and 1.27mm terminal pitch facilitate reliable PCB mounting, while the ceramic substrate enhances thermal and mechanical durability.

GS4B037500GAT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Robust Ceramic Package: Superior heat dissipation and mechanical strength vs. plastic alternatives.
• BUS Circuit Design: Ideal for bus termination, pull-up/pull-down networks, and voltage division.
• Automotive-Grade Alternatives: While this model is not PPAP/automotive certified, its 125°C operating limit suits industrial and telecom applications.
• Compact SOIC-8 Footprint: 4.9mm × 5.99mm × 1.45mm dimensions optimize space in dense layouts.
• Non-RoHS Compliance: Suitable for legacy or specialized designs requiring leaded components.

GS4B037500GAT Applications

• Signal Conditioning: Precision resistor networks for ADC/DAC interfaces and sensor calibration.
