GQCB0254R9JDT Description

The GQCB0254R9JDT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications in demanding electronic circuits. This 24-pin QSOP package integrates 23 resistors with a 54.9Ω resistance value, offering a 5% tolerance and a ±50ppm/°C temperature coefficient for stable operation across a -70°C to +125°C range. The ceramic case ensures robust thermal and mechanical performance, while the gull-wing termination facilitates reliable surface-mount (SMD) assembly. With a 1W total power rating (0.05W per resistor) and a 100V maximum voltage rating, this network is ideal for bus termination, voltage division, and impedance matching in compact designs.

GQCB0254R9JDT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Compact QSOP Package: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerances ensure space efficiency.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power at elevated temperatures.
• High Power Handling: 1W total dissipation (distributed across 23 resistors) suits power-sensitive applications.
• Automated Assembly-Friendly: Gull-wing leads and 0.64mm terminal pitch optimize pick-and-place compatibility.
• Non-RoHS (Not Compliant): Suitable for legacy or specialized industrial systems where RoHS exemptions apply.
