GQ0A0245R3DT

GQ0A0245R3DT Description

The GQ0A0245R3DT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP package integrates 10 isolated resistors, each with a 45.3 Ω resistance, 0.5% tolerance, and a ±50ppm/°C temperature coefficient, ensuring exceptional stability across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination enable reliable surface-mount (SMD) assembly, while the 100V maximum voltage rating and 1W total power dissipation (0.1W per resistor) make it suitable for high-density circuits. Packaged in a tube, this non-automotive, non-RoHS compliant component is ideal for industrial and instrumentation use where precision and durability are critical.

GQ0A0245R3DT Features

• Precision Thin Film Technology: Delivers 0.5% tolerance and low TCR (±50ppm/°C) for stable performance in thermal variations.
• Robust Construction: Ceramic substrate and QSOP package ensure mechanical strength and heat dissipation.
• High Voltage Isolation: 100V rating per resistor, with 10 isolated channels (designated ISOL) for signal integrity.
• Compact & Efficient: 8.66mm x 6.02mm footprint and 1.47mm profile save PCB space in dense layouts.
• Derated Power Handling: Operates at 70–125°C with derated power, exceeding standard industrial requirements.
