GQ0A014422BT

GQ0A014422BT Description

The GQ0A014422BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding isolation and signal conditioning applications. This 20-pin QSOP (Quarter-Small Outline Package) device features 10 isolated resistors, each with a 44.2KΩ resistance and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in circuit designs. The ceramic case style and gull-wing termination enable reliable surface-mount (SMD) integration, while the ±100ppm/°C temperature coefficient guarantees stable performance across a wide operating range of 70°C to 125°C. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network is engineered for precision analog and digital systems requiring minimal drift and high isolation.

GQ0A014422BT Features

• High Precision: 0.1% tolerance and ±100ppm/°C TCR for critical applications.
• Robust Construction: Ceramic substrate enhances thermal stability and durability.
• Isolated Design: 10 independent resistors (ISOL circuit designator) prevent crosstalk.
• Compact Form Factor: QSOP package (8.66mm x 6.02mm x 1.47mm) saves PCB space.
• Surface-Mount Ready: Gull-wing terminals with 0.64mm pitch for automated assembly.
• Wide Temperature Range: Operates reliably from 70°C to 125°C with derated power.
• Non-Automotive: Suitable for industrial, medical, and telecom applications (PPAP: No).
