GQCB011400DDT Description

The GQCB011400DDT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 23-resistor array features a 140 Ohm resistance value with a tight 0.5% 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. The gull-wing termination and surface-mount design facilitate easy PCB integration, while the 1W total power rating (0.05W per resistor) makes it suitable for power-sensitive circuits.

GQCB011400DDT Features

• Precision Performance: 0.5% tolerance and ±100ppm/°C TCR for high-accuracy signal conditioning.
• Robust Construction: Ceramic case ensures durability and thermal efficiency.
• Space-Efficient: Compact QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm terminal pitch for high-density layouts.
• Wide Voltage Range: Supports up to 100V maximum voltage, ideal for industrial and automotive systems (though not PPAP/automotive-qualified).
• Stable Power Handling: 1W total dissipation (0.05W per resistor) with derating up to 125°C.
• Non-RoHS Compliant: Suitable for legacy or specialized applications requiring non-compliant materials.

GQCB011400DDT Applications

This resistor network excels in:

• Analog Signal Processing: Precision dividers, DAC/ADC reference circuits.
• Industrial Controls: Feedback networks, sensor conditioning in harsh environments.
• Test & Measurement Equipment: Calibration circuits requiring low drift.
