GS4A021872FT

GS4A021872FT Description

The GS4A021872FT from TT Electronics/IRC is a high-performance ceramic resistor network designed for precision applications. This 8-pin narrow SOIC package features four isolated thin-film resistors, each with a resistance value of 18.7KΩ and a tight ±1% tolerance. The device operates within a wide temperature range of 70°C to 125°C (derated) and delivers a power rating of 0.1W per resistor (0.4W total). Its ±50ppm/°C temperature coefficient ensures stability under thermal stress, while the 100V maximum voltage rating makes it suitable for medium-voltage circuits. Encased in a rectangular ceramic SOIC package, it offers excellent thermal and mechanical durability.

GS4A021872FT Features

• Isolated Resistor Network: Four independent resistors with no shared node, ideal for signal isolation.
• Precision Thin-Film Technology: Delivers low TCR (±50ppm/°C) and high accuracy (±1%).
• Robust Ceramic Package: Ensures thermal stability and mechanical strength in harsh environments.
• Surface-Mount Gull Wing Termination: Facilitates reliable PCB assembly with a 1.27mm terminal pitch.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
• Non-Automotive, Non-PPAP: Optimized for industrial and commercial applications.
