GQ0A0228R7GFT Description

The GQ0A0228R7GFT 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 resistance value of 28.7Ω, a tight tolerance of ±2%, and a low temperature coefficient of ±50ppm/°C. Encased in a robust ceramic package, it offers excellent thermal stability and reliability across an operating temperature range of -70°C to +125°C. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is engineered for precision and durability in surface-mount applications.

GQ0A0228R7GFT Features

• High Isolation Performance: Designed with isolated resistors (ISOL circuit designator), minimizing crosstalk and ensuring signal integrity in multi-channel systems.
• Thin-Film Technology: Delivers superior accuracy, low noise, and stability compared to thick-film alternatives.
• Compact & Robust: Ceramic QSOP package (8.66mm x 6.02mm x 1.47mm) with gull-wing terminals for reliable SMT assembly and high-density PCB layouts.
• Wide Temperature Range: Operates reliably from -70°C to +125°C, with derated power up to 125°C.
• Low TCR (±50ppm/°C): Ensures minimal resistance drift under thermal stress, critical for precision analog circuits.
