GQ0A021371BT Description

The GQ0A021371BT 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 1.37KΩ resistance value, a tight 0.1% tolerance, and a low ±50ppm/°C temperature coefficient. Encased in a ceramic package, it offers superior thermal stability and reliability in harsh environments, with an operating temperature range of 70°C to 125°C. The gull-wing termination ensures secure surface-mount (SMD) attachment, while the 0.64mm terminal pitch accommodates high-density PCB layouts. With a 1W total power rating (0.1W per resistor) and a 100V maximum voltage rating, this network is ideal for precision analog and digital circuits.

GQ0A021371BT Features

• High Precision: 0.1% tolerance and ±50ppm/°C TCR ensure minimal drift in critical applications.
• Robust Construction: Ceramic case enhances thermal dissipation and mechanical durability.
• Isolated Design: 10 independent resistors (ISOL circuit designator) prevent crosstalk in multi-channel systems.
• Space-Efficient: QSOP package (8.66mm × 6.02mm × 1.63mm) with 0.64mm pitch suits compact designs.
• Reliable Performance: 125°C maximum operating temperature and 1W total power handling support sustained operation.
• Compliance: EAR99 ECCN (export-friendly), though non-RoHS (restricted for certain regions).
