GS4A021272FBT Description

The GS4A021272FBT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding electronic applications. This 8-pin narrow SOIC device features four isolated thin-film resistors, each with a 12.7KΩ resistance and a tight ±1% absolute tolerance, ensuring exceptional accuracy. The network operates over a wide temperature range (70°C to 125°C) with a low ±50ppm/°C temperature coefficient, making it ideal for stable performance in varying thermal conditions. Encased in a rectangular ceramic SOIC package, it offers 0.1W power dissipation per resistor (0.4W total) and a 100V maximum voltage rating, suitable for high-reliability circuits.

GS4A021272FBT Features

• Isolated Resistors: Four independent resistors in an 8-pin SOIC package, ensuring minimal crosstalk.
• Precision Tolerance: ±1% absolute tolerance and ±0.1% ratio tolerance for high-accuracy applications.
• Stable Performance: Low ±50ppm/°C TCR and 125°C maximum operating temperature for reliable operation under thermal stress.
• Robust Construction: Ceramic case with gull-wing termination, providing mechanical durability and ease of surface-mount assembly.
• Compact Dimensions: 4.9mm (L) × 5.99mm (D) × 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).
