GS4A019102FFT

GS4A019102FFT Description

The GS4A019102FFT from TT Electronics/IRC is a high-performance 4-resistor network designed for precision applications requiring stable resistance values and tight tolerances. Housed in an 8-pin narrow SOIC (SOIC-C) ceramic package, this thin-film resistor network offers 91KΩ resistance per element with an absolute tolerance of ±1% and a ratio tolerance of ±1%. Its isolated circuit design (ISOL) ensures independent resistor performance, making it suitable for signal conditioning, voltage division, and impedance matching. With a ±100ppm/°C temperature coefficient, it maintains stability across a wide operating range of -70°C to +125°C. The 0.1W power rating per resistor (0.4W total) and 100V maximum voltage rating ensure reliability in demanding environments.

GS4A019102FFT Features

• Ceramic SOIC Package: Robust rectangular ceramic case (4.9mm x 5.99mm x 1.45mm) with gull-wing termination for secure surface mounting.
• Precision Thin Film: ±1% tolerance and ±100ppm/°C TCR for consistent performance under thermal stress.
• Isolated Resistors: Independent elements reduce crosstalk, ideal for multi-channel circuits.
• High-Temperature Operation: Rated for 125°C maximum, with derated power up to 125°C.
• Stable Power Handling: 0.4W total dissipation (0.1W per resistor) ensures durability in compact designs.
• Non-Automotive, Non-PPAP: Suitable for industrial, telecom, and instrumentation applications.
