GQCA023570GT

GQCA023570GT Description

The GQCA023570GT from TT Electronics/IRC is a high-performance thin-film resistor network designed for precision applications requiring stable resistance values and reliable isolation. This 24-pin QSOP (Quarter Small Outline Package) device features 12 isolated resistors, each with a 357 Ω resistance value and a tight 2% tolerance. Encased in a ceramic package, it offers excellent thermal stability with a ±50 ppm/°C temperature coefficient, ensuring minimal drift across its operating range of 70°C to 125°C. Rated for 100V maximum voltage and 0.1W power dissipation per resistor (1W total), this surface-mount network is ideal for demanding environments where accuracy and durability are critical.

GQCA023570GT Features

• High Precision: Thin-film technology delivers ±2% tolerance and ±50 ppm/°C TCR for stable performance.
• Robust Construction: Ceramic case enhances thermal and mechanical reliability.
• Isolated Design: 12 independent resistors prevent crosstalk, suitable for signal isolation.
• Space-Efficient: Compact QSOP package (8.66 x 6.02 x 1.47 mm) with 0.64 mm pitch gull-wing leads for high-density PCB layouts.
• Wide Operating Range: Functions reliably from -55°C to +125°C (derated power up to 125°C).
• Non-Automotive: Compliant with EAR99 ECCN but not PPAP or automotive-grade.

GQCA023570GT Applications

This resistor network excels in:

• Precision Analog Circuits: Voltage dividers, feedback networks, and sensor interfaces.
• Industrial Electronics: PLCs, motor controls, and instrumentation requiring isolation.
• Telecom & Networking: Signal conditioning and impedance matching in high-frequency systems.
• Medical Devices: Low-noise, stable resistance for diagnostic equipment.
• Test & Measurement: Calibration and reference circuits due to its low drift.

Conclusion of GQCA023570GT
