GS4A012942FFT

GS4A012942FFT Description

The GS4A012942FFT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 29.4KΩ resistance and a tight ±1% absolute tolerance. The SOIC-C series construction ensures robust performance with a ±100ppm/°C temperature coefficient, making it suitable for stable operation across a 70°C to 125°C derated power range. With a maximum operating temperature of 125°C and a 100V voltage rating, this network is engineered for reliability in demanding environments. The gull-wing termination and surface-mount design facilitate easy integration into compact PCB layouts.

GS4A012942FFT Features

• Isolated Elements: Four independent resistors ensure minimal crosstalk, ideal for precision circuits.
• High Stability: Thin-film technology and ±100ppm/°C TCR deliver consistent performance under thermal stress.
• Compact & Robust: Ceramic case with 4.9mm × 5.99mm × 1.45mm dimensions (±0.1mm tolerance) and 1.27mm terminal pitch for space-constrained designs.
• Power Handling: 0.1W per resistor (0.4W total) with derating up to 125°C.
• Automotive-Grade Alternatives: While not PPAP or automotive-certified, its high-temperature resilience suits industrial and telecom applications.
