GQ0B0256R2GDT Description

The GQ0B0256R2GDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 19-resistor BUS-configuration array offers a 56.2Ω resistance per element with a tight 2% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide operating temperature range of -55°C to +125°C. Housed in a 20-pin QSOP ceramic package, it features gull-wing SMD termination for reliable surface-mount assembly. With a 0.05W (1/20) power rating per resistor and a 1W total power dissipation, this network is engineered for precision signal conditioning, voltage division, and impedance matching in compact PCB layouts.

GQ0B0256R2GDT Features

• Ceramic QSOP Package: Robust rectangular ceramic case (8.66mm × 6.02mm × 1.47mm) with ±0.1mm dimensional tolerances ensures mechanical stability and thermal endurance.
• Thin-Film Technology: Delivers superior accuracy (±2%), low noise, and ±50ppm/°C TCR for precision analog/digital circuits.
• High Voltage Rating: Supports up to 100V, making it suitable for industrial and instrumentation applications.
• BUS Configuration: 19 resistors with a common BUS design simplify PCB routing in multi-channel systems.
• Gull-Wing Termination: 0.64mm pitch SMD contacts enable high-density mounting and automated assembly.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C).

GQ0B0256R2GDT Applications
