GQCB028660JCT Description

The GQCB028660JCT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. It features 23 resistors in a 24-pin QSOP package with a rectangular ceramic case, offering a total resistance of 866Ω at 5% tolerance and a ±50ppm/°C temperature coefficient. With a 1W total power rating (0.05W per resistor), it operates reliably across a wide temperature range of 70°C to 125°C. The gull-wing termination and surface-mount design ensure easy integration into compact PCB layouts, while its 100V maximum voltage rating makes it suitable for robust circuit protection.

GQCB028660JCT Features

• High-Density Integration: 23 resistors in a compact QSOP-24 package (8.66mm x 6.02mm x 1.47mm) save board space.
• Precision Thin-Film Technology: Delivers stable performance with ±50ppm/°C TCR and 5% tolerance for consistent signal integrity.
• Robust Construction: Ceramic substrate enhances thermal stability and durability in harsh environments.
• Automated Assembly Friendly: Gull-wing leads and 0.64mm pitch enable high-speed SMT placement.
• Derated Power Handling: Maintains functionality up to 125°C with derated power, ideal for thermally demanding applications.

GQCB028660JCT Applications

• Signal Conditioning: Precision voltage dividers and pull-up/down networks in industrial control systems.
• Analog/Digital Interfaces: Bus termination and impedance matching in communication hardware (e.g., RS-485, CAN).
• Power Management: Current sensing and load balancing in DC-DC converters and power supplies.
• Automotive & Aerospace: Non-automotive grade but suitable for benchtop prototyping and non-safety-critical avionics due to its wide temperature range.
