GQ0A038451GT

GQ0A038451GT Description

The GQ0A038451GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and low temperature coefficients. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a resistance value of 8.45KΩ (±2% tolerance) and a power rating of 0.1W (1/10W) per resistor, totaling 1W for the entire network. Encased in a ceramic package, it offers superior thermal stability and durability, with an operating temperature range of 70°C to 125°C and a maximum voltage rating of 100V. The gull-wing termination ensures reliable surface-mount (SMD) connectivity, while its ±25ppm/°C temperature coefficient guarantees minimal resistance drift under varying thermal conditions.

GQ0A038451GT Features

• Precision Thin-Film Technology: Delivers high accuracy (±2%) and low TCR (±25ppm/°C) for stable performance in demanding environments.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical strength, ideal for high-reliability applications.
• Isolated Resistor Network (ISOL): Each of the 10 resistors is electrically isolated, providing flexibility in circuit design.
• Compact QSOP Package: Measures 8.66mm (L) x 6.02mm (D) x 1.47mm (H) with tight tolerances (±0.1mm L/H, ±0.2mm D), saving PCB space.
• Wide Temperature Range: Operates reliably from 70°C to 125°C, suitable for industrial and automotive-adjacent applications (though not PPAP/Automotive certified).
• Gull-Wing SMD Termination: Ensures secure mounting and solderability for automated assembly processes.

GQ0A038451GT Applications

This resistor network excels in precision analog and digital circuits, including:

• Signal Conditioning: Voltage dividers, feedback networks, and sensor interfaces in measurement equipment.
• Industrial Control Systems: PLCs, motor drives, and power supplies requiring stable resistance values.
• Medical Electronics: Patient monitoring devices and diagnostic instruments where accuracy is critical.
• Telecommunications: RF modules and baseband processing circuits needing low-noise performance.
• Test & Measurement: Calibration tools and reference circuits due to its low TCR and tight tolerance.
