GQ8A0135R7DCT Description

The GQ8A0135R7DCT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for isolation (ISOL) applications. Housed in a 16-pin QSOP ceramic package, it offers a 35.7Ω resistance per resistor with an ultra-tight ±0.5% tolerance and a low ±100ppm/°C temperature coefficient, ensuring stability across a wide operating range of 70°C to 125°C. With a 0.75W (3/4W) total power rating (0.1W per resistor) and 100V maximum voltage rating, this surface-mount network is engineered for reliability in demanding circuits. Its gull-wing termination and 0.64mm terminal pitch facilitate seamless PCB integration.

GQ8A0135R7DCT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog/digital circuits.
• Ceramic QSOP Case: Enhances thermal performance and mechanical durability vs. plastic alternatives.
• Isolated Resistor Design (ISOL): Each resistor operates independently, ideal for signal isolation or voltage division.
• High Power Density: 0.75W total dissipation in a compact 4.9mm × 6.02mm × 1.47mm footprint.
• Automotive-Grade Alternatives: While this model is not PPAP/Automotive compliant, its 125°C max temperature suits industrial and telecom applications.
• Non-RoHS (Not Compliant): Suitable for legacy or exempted systems requiring leaded components.
