GQ0A028450JBT Description

The GQ0A028450JBT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 10-resistor array features an 845Ω resistance value per resistor with a 5% tolerance and a ±50ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 20-pin QSOP ceramic package, it offers 1W total power dissipation (0.1W per resistor) and a 100V maximum voltage rating, making it suitable for demanding circuits. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the isolated (ISOL) circuit designator ensures flexibility in circuit configurations.

GQ0A028450JBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Robust Ceramic Package: Enhances thermal management and durability in harsh environments.
• Compact QSOP Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with tight tolerances (±0.1mm height/length) save board space.
• High Power Handling: 1W total (0.1W per resistor) supports power-dense designs.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated above 70°C).
• Gull-Wing SMD Termination: Ensures secure soldering and mechanical stability.

GQ0A028450JBT Applications
