GQ8B024421FDT Description

The GQ8B024421FDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 16-pin QSOP (Quarter Small Outline Package) device integrates 15 resistors with a 4.42KΩ resistance value, offering 1% tolerance and a ±50ppm/°C temperature coefficient for stable performance across a wide temperature range (70°C to 125°C). Encased in a ceramic package, it ensures durability and excellent thermal management, with a maximum operating temperature of 125°C. The gull-wing termination facilitates reliable surface-mount (SMD) assembly, while the 0.64mm terminal pitch supports high-density PCB layouts.

GQ8B024421FDT Features

• High Power Handling: Delivers 0.75W (3/4W) total power (0.05W per resistor), ideal for power-sensitive circuits.
• Precision Stability: ±50ppm/°C TCR and 1% tolerance ensure consistent performance in varying environments.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength.
• Compact Design: 4.9mm (L) × 6.02mm (D) × 1.47mm (H) dimensions with tight tolerances (±0.1mm height/length, ±0.2mm depth) for space-constrained applications.
• Automotive-Grade Alternatives: While not PPAP or automotive-certified, its 100V maximum voltage rating and reliability make it suitable for industrial and telecom systems.

GQ8B024421FDT Applications

• Signal Conditioning: Precision voltage dividers in data acquisition systems.
• Bus Termination: BUS circuit designator optimizes impedance matching in high-speed digital interfaces (e.g., DDR memory, FPGA layouts).
• Industrial Electronics: Stable performance in PLC modules, test equipment, and power supplies.
• Telecommunications: RF and analog circuits requiring low-noise, high-accuracy resistance networks.

Conclusion of GQ8B024421FDT

The GQ8B024421FDT excels in high-reliability applications where precision, thermal resilience, and compactness are critical. Its thin-film technology and ceramic encapsulation provide superior performance over polymer-based networks, while the QSOP gull-wing package ensures compatibility with automated assembly processes. Though non-compliant with EU RoHS, it remains a robust choice for industrial, telecom, and instrumentation designs requiring tight-tolerance resistor arrays.
