GQCA034221GFT

GQCA034221GFT Description

The GQCA034221GFT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications. This 24-pin QSOP package features 12 isolated resistors, each with a 4.22KΩ resistance, 2% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case style and gull-wing termination make it ideal for surface-mount (SMD) applications, while its 1W total power rating (0.1W per resistor) and 100V maximum voltage rating cater to demanding circuits. Packaged in a tube, this non-automotive, non-PPAP compliant component is suited for industrial and commercial use, though it is not EU RoHS compliant.

GQCA034221GFT Features

• Precision Thin Film Technology: Delivers low noise and high stability, critical for sensitive analog circuits.
• Isolated Resistor Network (ISOL): Each of the 12 resistors is electrically isolated, enabling flexible circuit design.
• Robust Ceramic Package: Enhances thermal performance and durability in harsh environments.
• Compact QSOP Form Factor: 8.66mm × 6.02mm × 1.47mm dimensions with ±0.1mm length/height tolerance ensure space-efficient PCB integration.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated above 70°C), outperforming standard networks in thermal resilience.
• Gull-Wing Termination: Facilitates reflow soldering and improves mechanical stress resistance.

GQCA034221GFT Applications

• Signal Conditioning: Ideal for ADC/DAC reference networks and voltage dividers in measurement equipment.
• Industrial Controls: Used in PLC modules, sensor interfaces, and power management systems due to its isolation and precision.
• Telecommunications: Supports impedance matching and filter networks in RF/microwave circuits.
• Medical Devices: Suitable for low-drift instrumentation where consistent resistance values are critical.
• Aerospace & Defense: Ceramic construction and thin-film technology meet reliability needs for avionics and military-grade hardware.
