GQCB011871FT Description

The GQCB011871FT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 23-resistor array features a 1.87KΩ resistance value per resistor with a tight 1% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range of 70°C to 125°C. Housed in a 24-pin QSOP ceramic package, it offers excellent thermal stability and reliability in compact, space-constrained designs. The gull-wing termination and surface-mount (SMD) configuration simplify PCB assembly, while the 1W total power rating (0.05W per resistor) makes it suitable for power-sensitive circuits.

GQCB011871FT Features

• Precision Thin Film Technology: Delivers low noise and high accuracy for signal conditioning and analog applications.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical durability in harsh environments.
• High-Density Integration: 23 resistors in a compact 8.66mm × 6.02mm × 1.47mm QSOP package optimize board space.
• Wide Voltage Range: Supports up to 100V, ideal for industrial and automotive systems (though not PPAP/automotive-certified).
• Stable Performance: ±0.1mm height/length tolerances and ±0.2mm depth tolerance ensure consistent mounting.
• Non-RoHS Compliant: Suitable for legacy or exempted applications requiring leaded components.

GQCB011871FT Applications

This resistor network excels in:

• Analog Signal Processing: Voltage dividers, DAC/ADC reference circuits, and sensor interfaces.
• Industrial Control Systems: PLCs, motor drives, and power management modules requiring precision resistance.
• Test & Measurement Equipment: Calibration circuits and instrumentation where stability is critical.
• Telecommunications: Filter networks and impedance matching in RF/mixed-signal PCBs.
• Legacy Electronics Repair: Non-RoHS compliance makes it a fit for older or specialized hardware.
