GQCA021303CBT

GQCA021303CBT Description

The GQCA021303CBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 24-pin QSOP package features 12 isolated resistors, each with a 130K Ohm resistance value and an ultra-tight 0.25% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) assembly, while the ±50ppm/°C temperature coefficient guarantees stable performance across a wide operating range of 70°C to 125°C. With a maximum voltage rating of 100V and a power rating of 1W (0.1W per resistor), this network is engineered for precision analog and mixed-signal systems.

GQCA021303CBT Features

• High Precision: 0.25% tolerance and ±50ppm/°C TCR for minimal drift in critical circuits.
• Robust Construction: Ceramic substrate enhances thermal stability and durability.
• Isolated Design: 12 independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel applications.
• Space-Efficient: Compact QSOP package (8.66mm x 6.02mm x 1.47mm) with 0.64mm pitch for high-density PCB layouts.
• Reliable Termination: Gull-wing leads ensure secure solder joints and mechanical resilience.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power handling.

GQCA021303CBT Applications

• Precision Instrumentation: Ideal for DAQ systems, medical devices, and test equipment requiring stable resistance values.
• Industrial Controls: Suitable for PLC modules, motor drivers, and power management circuits due to its high voltage rating.
• Telecommunications: Used in RF signal conditioning and filtering networks where low tolerance and isolation are critical.
• Automotive Electronics: While not automotive-grade, it fits non-safety-critical automotive subsystems like infotainment or sensors.
• Aerospace & Defense: Thin-film reliability and ceramic construction make it viable for avionics and ruggedized systems.

Conclusion of GQCA021303CBT

The GQCA021303CBT stands out for its combination of precision, isolation, and power handling in a compact SMD format. Its ceramic thin-film technology and tight electrical specs make it superior to standard thick-film networks in applications demanding long-term stability. While not PPAP or RoHS compliant, it remains a cost-effective choice for industrial, telecom, and high-end consumer electronics where accuracy and thermal performance are paramount. Engineers should consider this model for designs requiring repeatable performance under thermal stress and space constraints.
