GQCB0259R0GDT Description

The GQCB0259R0GDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for surface-mount applications requiring stable performance in demanding environments. Encased in a 24-pin QSOP ceramic package, it integrates 23 resistors with a 59Ω resistance value, 2% tolerance, and a ±50ppm/°C temperature coefficient, ensuring reliable operation across a -55°C to +125°C range. With a 1W total power rating (0.05W per resistor) and 100V maximum voltage rating, this network excels in signal conditioning, voltage division, and bus termination circuits. Its gull-wing termination and 0.64mm pitch facilitate compact PCB layouts, while the ceramic case enhances thermal stability.

GQCB0259R0GDT Features

• Precision Thin Film Technology: Delivers low noise and high stability for critical analog/digital circuits.
• Robust Ceramic Package: Withstands high temperatures (up to 125°C) and mechanical stress.
• Optimized Power Handling: 1W total dissipation (distributed across 23 resistors) suits power-sensitive designs.
• BUS Circuit Designator: Ideal for bus termination, pull-up/pull-down networks, and impedance matching.
• QSOP Gull-Wing SMD: Enables high-density mounting with 6.02mm × 8.66mm footprint and 1.47mm profile.
• Non-Automotive Grade: Best for industrial, telecom, and instrumentation applications where PPAP compliance isn’t required.

GQCB0259R0GDT Applications

• Digital Systems: Bus termination for FPGA, ASIC, and memory interfaces to reduce signal reflections.
• Analog Signal Processing: Voltage dividers in sensor interfaces, ADCs, and DACs.
• Power Management: Current-limiting networks in low-power DC/DC converters.
• Test & Measurement Equipment: Precision reference circuits due to ±50ppm/°C TCR.
• Industrial Controls: Durable solution for PLC I/O modules exposed to thermal cycling.
