GQ0A028252FT Description

The GQ0A028252FT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 82.5KΩ resistance value and a tight 1% tolerance. Encased in a ceramic package, it offers superior thermal stability and durability, with a maximum operating temperature of 125°C. The network operates at 0.1W per resistor (1W total), with a ±50ppm/°C temperature coefficient, ensuring minimal drift across its 70°C to 125°C derated power range. Its gull-wing termination and surface-mount design facilitate easy PCB integration, while the 100V maximum voltage rating makes it suitable for high-voltage circuits.

GQ0A028252FT Features

• Precision Performance: Thin-film technology delivers low noise, high stability, and 1% tolerance for critical analog/digital circuits.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical strength, ideal for harsh environments.
• Space-Efficient: Compact QSOP package (8.66mm × 6.02mm × 1.47mm) with 0.64mm pitch maximizes board space utilization.
• Isolated Design: 10 independent resistors (ISOL circuit designator) prevent crosstalk, perfect for multi-channel systems.
• Wide Temperature Range: Operates reliably from -55°C to +125°C (derated above 70°C).
• Non-Automotive: Compliant with general industrial standards (EAR99 ECCN, non-PPAP).

GQ0A028252FT Applications

This resistor network excels in:

• Precision voltage dividers and signal conditioning in test/measurement equipment.
• Analog-to-digital converters (ADCs) and digital-to-analog converters (DACs) requiring matched resistances.
• Medical electronics, where low drift and reliability are critical.
• Industrial control systems leveraging its isolation for noise immunity.
• High-voltage power supplies and telecom infrastructure due to its 100V rating.
