GQCB0268R0GDT

GQCB0268R0GDT Description

The GQCB0268R0GDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding surface-mount applications. This 24-pin QSOP package integrates 23 resistors with a 68Ω resistance value, offering a tight 2% tolerance and a low ±50ppm/°C temperature coefficient. Encased in a ceramic substrate, it ensures superior thermal stability and mechanical robustness. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, it operates reliably across a wide temperature range of 70°C to 125°C. The gull-wing termination and 0.64mm pitch facilitate easy PCB integration, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs.

GQCB0268R0GDT Features

• Precision Thin Film Technology: Delivers stable performance with low noise and high accuracy.
• Ceramic Case: Enhances thermal dissipation and durability in harsh environments.
• BUS Circuit Designator: Optimized for bus line termination and signal conditioning.
• High Power Handling: 1W total dissipation (1/20W per resistor) ensures reliability in power-sensitive circuits.
• Wide Operating Range: Supports temperatures up to 125°C, suitable for industrial and automotive (non-AECQ) applications.
• RoHS Non-Compliant: Contains lead, making it compatible with legacy systems requiring Pb-based soldering.
