GQ0A024421DBT Description

The GQ0A024421DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP surface-mount device integrates 10 isolated resistors, each with a 4.42KΩ resistance and a tight 0.5% tolerance, ensuring exceptional accuracy in circuit matching. The ceramic case and gull-wing termination provide robust mechanical stability and reliable solderability, while the ±50ppm/°C temperature coefficient guarantees stable performance across a wide operating range of 70°C to 125°C. With a 100V maximum voltage rating and 1W total power dissipation, this network is engineered for precision analog and digital systems.

GQ0A024421DBT Features

• High Precision: 0.5% tolerance and ±50ppm/°C TCR for consistent performance in temperature-varying environments.
• Robust Construction: Ceramic case and gull-wing terminals ensure durability and ease of surface-mount assembly.
• Isolated Design: 10 resistors with independent isolation (ISOL) minimize crosstalk in sensitive circuits.
• Power Efficiency: 0.1W per resistor (1W total) balances thermal management and compact sizing (8.66mm x 6.02mm x 1.47mm).
• Wide Voltage Range: Supports up to 100V, ideal for industrial and instrumentation applications.
• Non-Automotive Grade: Suitable for commercial and industrial use but not PPAP-compliant.
