GQ8A021302BT

GQ8A021302BT Description

The GQ8A021302BT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding isolation and signal conditioning applications. Housed in a 16-pin QSOP ceramic package, it features 13KΩ resistance per element with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating temperature range of 70°C to 125°C. The isolated (ISOL) circuit design eliminates crosstalk, making it ideal for precision analog and digital systems. With a 0.75W total power rating (0.1W per resistor) and 100V maximum voltage rating, it balances performance and reliability in compact designs. The gull-wing termination and surface-mount (SMD) form factor simplify PCB integration.

GQ8A021302BT Features

• Precision Thin Film Technology: Delivers ±0.1% tolerance and ±50ppm/°C TCR for stable performance in thermal variations.
• Robust Ceramic Package: Enhances thermal management and mechanical durability vs. plastic alternatives.
• Isolated Resistor Network: Each of the 8 resistors is electrically isolated (ISOL), reducing interference in multi-channel systems.
• High Power Density: 0.75W total dissipation (0.1W per resistor) in a compact 4.9mm × 6.02mm × 1.47mm footprint.
• Wide Voltage Range: Supports up to 100V, suitable for industrial and instrumentation applications.
• Strict Dimensional Tolerances: ±0.1mm height/length and ±0.2mm depth ensure consistent PCB assembly.
