GQCA033090GGT

GQCA033090GGT Description

The GQCA033090GGT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP package features 12 isolated resistors, each with a 309Ω resistance value and a tight 2% tolerance. Built on a ceramic substrate, it offers excellent thermal stability with a ±25ppm/°C temperature coefficient, ensuring reliable performance across a 70°C to 125°C operating range. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for demanding circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the tube packaging ensures safe handling and storage.

GQCA033090GGT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Isolated Resistor Network (ISOL): Each of the 12 resistors operates independently, ideal for multi-channel isolation.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical durability in harsh environments.
• Compact QSOP Package (8.66mm x 6.02mm x 1.47mm): Saves board space without compromising performance.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Low TCR (±25ppm/°C): Minimizes resistance drift under thermal stress.

GQCA033090GGT Applications

This resistor network excels in:

• Industrial Control Systems: Signal conditioning, feedback loops, and voltage division in PLCs.
• Medical Electronics: Precision instrumentation where stability and isolation are critical.
• Telecommunications: Impedance matching and line termination in high-frequency circuits.
• Automotive (Non-Automotive Compliant): Prototyping or non-safety-critical modules requiring tight tolerance.
• Test & Measurement Equipment: Calibration and reference circuits due to low TCR and high accuracy.
