GQ8A028251BBT Description

The GQ8A028251BBT from TT Electronics/IRC is a high-precision 8-resistor thin-film network designed for demanding isolation and signal conditioning applications. Encased in a ceramic QSOP package, it offers an 8.25KΩ resistance per resistor with an ultra-tight 0.1% tolerance and a low ±50ppm/°C temperature coefficient, ensuring stability across a wide operating range of -70°C to +125°C. The 16-pin gull-wing SMD configuration provides reliable surface-mount compatibility, while the 0.1W (1/10W) power rating per resistor and 0.75W (3/4W) total power rating make it suitable for power-sensitive designs. Its 100V maximum voltage rating and isolated (ISOL) circuit design enhance safety in high-voltage environments.

GQ8A028251BBT Features

• Precision Thin-Film Technology: Delivers exceptional accuracy (±0.1%) and low TCR (±50ppm/°C) for stable performance.
• Robust Ceramic Package: Ensures thermal stability and durability in harsh conditions.
• High-Density QSOP-16: Compact 4.9mm × 6.02mm × 1.47mm footprint with 0.64mm pitch, ideal for space-constrained PCBs.
• Isolated Resistor Network (ISOL): Prevents crosstalk, making it perfect for analog signal isolation.
• Wide Temperature Range: Operates reliably from -70°C to +125°C with derated power up to 125°C.
• Gull-Wing Termination: Facilitates automated assembly and strong solder joints.
