GQ0A022742BT Description

The GQ0A022742BT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP (Quarter Small Outline Package) device features 10 isolated resistors, each with a 27.4KΩ resistance value and an ultra-tight 0.1% tolerance, ensuring exceptional accuracy in signal conditioning and voltage division circuits. The ceramic case construction provides superior thermal stability, with a ±50ppm/°C temperature coefficient and a wide operating range of -70°C to +125°C, making it suitable for harsh environments. With a 1W total power rating (0.1W per resistor) and 100V maximum voltage rating, this network offers robust performance in compact surface-mount (SMD) designs.

GQ0A022742BT Features

• Precision Thin Film Technology: Delivers low noise and high stability for sensitive analog circuits.
• Isolated Resistor Network (ISOL): 10 independent resistors minimize crosstalk in multi-channel systems.
• Ceramic QSOP Package: Enhances thermal dissipation and mechanical durability.
• Gull Wing Termination: Facilitates reliable soldering and PCB compatibility.
