GQ0A021581FBT Description

The GQ0A021581FBT from TT Electronics/IRC is a high-precision thin-film resistor network designed for demanding electronic applications. This 20-pin QSOP package features 10 isolated resistors, each with a 1.58KΩ resistance, 1% tolerance, and a ±50ppm/°C temperature coefficient. Encased in a ceramic housing, it offers superior thermal stability and durability, with a power rating of 0.1W per resistor (1W total). The gull-wing termination ensures reliable surface-mount (SMD) compatibility, while its compact dimensions (8.66mm x 6.02mm x 1.47mm) make it ideal for space-constrained designs. Rated for 100V maximum voltage and 125°C maximum operating temperature, it excels in high-reliability environments.

GQ0A021581FBT Features

• Precision Performance: Thin-film technology ensures low noise, high stability, and tight tolerance (±1%).
• Robust Construction: Ceramic case provides excellent thermal dissipation and mechanical strength.
• Isolated Design: 10 independent resistors (ISOL circuit designator) reduce crosstalk in sensitive circuits.
• Wide Temperature Range: Operates from 70°C to 125°C with derated power, suitable for industrial applications.
• Surface-Mount Ready: Gull-wing leads and 0.64mm pitch enable easy PCB integration.
• Non-Automotive: Compliant with EAR99 ECCN but not PPAP or automotive-grade, ideal for industrial/consumer electronics.

GQ0A021581FBT Applications

This resistor network is optimized for:

• Signal Conditioning: Precision voltage dividers in instrumentation and sensor interfaces.
• Medical Devices: Stable resistance networks in diagnostic equipment where accuracy is critical.
• Telecommunications: Impedance matching and termination in high-frequency RF circuits.
