GQ8A021692CT Description

The GQ8A021692CT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 8-resistor array features a 16.9KΩ resistance per element with an ultra-tight ±0.25% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stable performance across a wide -70°C to +125°C operating range. Housed in a ceramic QSOP-16 package, it offers 0.75W (3/4W) total power dissipation (0.1W per resistor) and 100V maximum voltage rating, making it suitable for high-reliability circuits. The gull-wing SMD termination ensures robust surface-mount compatibility, while its isolated (ISOL) circuit design provides flexibility in circuit configurations.

GQ8A021692CT Features

• Precision Thin Film Technology: Delivers high accuracy (±0.25%) and low TCR (±50ppm/°C) for stable performance in temperature-variable environments.
• Robust Ceramic Package: Enhances thermal management and mechanical durability compared to plastic alternatives.
• High Power Handling: Supports 0.75W total power (0.1W per resistor) with derating up to 125°C.
• Isolated Resistor Network: Enables independent resistor usage, ideal for differential signaling or voltage division.
• Compact QSOP-16 Form Factor: 4.9mm × 6.02mm × 1.47mm dimensions with 0.64mm pitch, optimizing PCB space in dense layouts.
• Non-Automotive, Non-RoHS: Suitable for industrial and non-regulated applications where RoHS compliance is not critical.
