GQ0A031211FBT Description

The GQ0A031211FBT 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 1.21KΩ resistance, 1% tolerance, and a ±25ppm/°C temperature coefficient, ensuring stable performance across a wide temperature range (70°C to 125°C). The ceramic case and gull-wing termination provide robust mechanical and electrical reliability, making it suitable for surface-mount (SMD) applications. With a 0.1W power rating per resistor (1W total) and a 100V maximum voltage rating, this network is engineered for precision signal conditioning and voltage division in compact designs.

GQQ0A031211FBT Features

• High Precision: Thin-film technology delivers ±1% tolerance and low TCR (±25ppm/°C) for stable operation.
• Isolated Resistors: 10 independent resistors (ISOL circuit design) enable flexible circuit configurations.
• Robust Construction: Ceramic case and gull-wing terminals ensure durability and solderability.
• Compact & Reliable: QSOP package (8.66mm × 6.02mm × 1.47mm) with tight tolerances (±0.1mm length/height) for high-density PCBs.
• Wide Operating Range: Rated for -55°C to +125°C, derated up to 125°C, ideal for industrial environments.
• Non-Automotive: Not PPAP-capable, but suited for test equipment, medical devices, and telecom systems.
