GQ0A034221BBT Description

The GQ0A034221BBT is a high-precision thin-film resistor network from TT Electronics/IRC, designed for demanding applications requiring tight tolerance and stable performance. This 20-pin QSOP package features 10 isolated resistors, each with a 4.22KΩ resistance value and an exceptional ±0.1% tolerance. The ceramic case ensures durability, while the thin-film technology delivers low noise and high reliability. With a ±25ppm/°C temperature coefficient, it maintains stability across a wide operating temperature range of 70°C to 125°C. The 1W total power rating (0.1W per resistor) and 100V maximum voltage rating make it suitable for precision analog and digital circuits.

GQ0A034221BBT Features

• High Precision: ±0.1% tolerance ensures minimal deviation in critical circuits.
• Stable Performance: ±25ppm/°C TCR guarantees consistency across temperature fluctuations.
