GQCA011021GT

GQCA011021GT Description

The GQCA011021GT 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 1.02KΩ resistance, 2% tolerance, and a ±100ppm/°C temperature coefficient. Encased in a ceramic substrate, it ensures excellent thermal stability and durability. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this component operates reliably across a 70°C to 125°C temperature range. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the tube packaging ensures safe handling and storage.

GQCA011021GT Features

• Precision Thin Film Technology: Delivers stable performance with low noise and high accuracy.
• Isolated Resistor Network (ISOL): Each resistor operates independently, reducing crosstalk in sensitive circuits.
• Robust Ceramic Case: Enhances thermal dissipation and mechanical strength.
• Wide Operating Range: Suitable for harsh environments (-70°C to +125°C with derating).
• Compact QSOP Package: Saves board space (8.66mm × 6.02mm × 1.47mm) with a 0.64mm terminal pitch for high-density layouts.
• Automotive-Grade Alternatives: While not PPAP or automotive-qualified, its reliability makes it a candidate for industrial and telecom applications.

GQCA011021GT Applications

Ideal for precision analog circuits, signal conditioning, and voltage division in:

• Test & Measurement Equipment: High-accuracy multichannel systems.
• Medical Electronics: Patient monitoring devices requiring stable resistance.
• Industrial Controls: PLCs and sensor interfaces where isolation is critical.
• Telecommunications: RF and baseband signal processing.
• Power Management: Feedback networks in DC-DC converters.

Conclusion of GQCA011021GT
