GQ0A033921DBT Description

The GQ0A033921DBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 3.92KΩ resistance and a tight 0.5% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case provides robust thermal and mechanical stability, while the gull-wing termination enables reliable surface-mount (SMD) assembly. With a ±25ppm/°C temperature coefficient, this network maintains stable performance across a wide temperature range (70°C to 125°C). Its 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for high-reliability environments.

GQ0A033921DBT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Isolated Resistors (ISOL): Each of the 10 resistors operates independently, reducing crosstalk.
• Ceramic Construction: Enhances thermal dissipation and durability in harsh conditions.
• 0.5% Tolerance & ±25ppm/°C TCR: Ideal for precision applications requiring minimal drift.
• QSOP Package (8.66mm x 6.02mm): Compact footprint saves PCB space without compromising performance.
• Gull Wing Termination: Ensures secure soldering and compatibility with automated assembly processes.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated above 70°C).
