GQCB014121DT

GQCB014121DT Description

The GQCB014121DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 23-resistor array features a 4.12KΩ resistance value per resistor with an ultra-tight 0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). Housed in a 24-pin QSOP ceramic package, it offers excellent thermal stability and durability. The gull-wing termination facilitates reliable surface-mount (SMD) assembly, while the 1W total power rating (0.05W per resistor) supports moderate power dissipation. With a 100V maximum voltage rating, this network is ideal for precision analog and digital circuits.

GQCB014121DT Features

• Precision Thin Film Technology: Delivers high accuracy (±0.5%) and low TCR (±100ppm/°C) for stable performance.
• Robust Ceramic Package: Enhances thermal management and mechanical strength in harsh environments.
• High-Density Integration: 23 resistors in a compact QSOP-24 (8.66mm x 6.02mm x 1.47mm) footprint.
• Gull-Wing SMD Termination: Ensures reliable PCB mounting and solder joint integrity.
• Wide Operating Range: Rated for -55°C to +125°C, suitable for industrial and automotive-grade designs (though non-PPAP).
• Low Power Dissipation: 0.05W per resistor (1W total) balances performance and energy efficiency.

GQCB014121DT Applications

This resistor network excels in:

• Analog Signal Conditioning: Precision voltage dividers, feedback networks in op-amps.
