GS4A011020FT

GS4A011020FT Description

The GS4A011020FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications requiring stable resistance values and robust thermal performance. Housed in an 8-pin narrow SOIC package, this 4-resistor isolated network features 102Ω resistance per element with a tight ±1% tolerance and a low ±100ppm/°C temperature coefficient. Its thin-film technology ensures excellent stability and reliability, while the ceramic case style enhances thermal dissipation. Rated for 0.1W per resistor (0.4W total), it operates across a wide temperature range of 70°C to 125°C, with a maximum voltage rating of 100V. The gull-wing termination and surface-mount design facilitate easy PCB integration.

GS4A011020FT Features

• Precision Performance: ±1% absolute tolerance and ±100ppm/°C TCR for consistent operation in demanding environments.
• Robust Construction: Ceramic substrate ensures superior thermal management and mechanical durability.
• Isolated Design: Four independent resistors (isolated elements) minimize crosstalk, ideal for signal conditioning.
• Compact Footprint: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• High-Temperature Capability: Derated power up to 125°C, suitable for industrial and automotive-adjacent applications.
• Compatibility: SOIC package with 1.27mm terminal pitch aligns with standard SMT assembly processes.
