GS4A011301BT

GS4A011301BT Description

The GS4A011301BT from TT Electronics/IRC is a high-precision ceramic resistor network designed for demanding applications requiring tight tolerance and stability. Housed in an 8-pin narrow SOIC package, it features four isolated thin-film resistors, each with a 1.3 kΩ resistance and an exceptional ±0.1% absolute tolerance. The device operates over a wide temperature range of -55°C to +125°C, with a derated power range of 70°C to 125°C, ensuring reliable performance in thermally challenging environments. Its ±100 ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for precision analog and digital circuits.

GS4A011301BT Features

• High Precision: ±0.1% tolerance ensures minimal deviation in critical circuits.
• Robust Construction: Ceramic case and thin-film technology provide excellent thermal stability and durability.
• Isolated Design: Four independent resistors (ISOL circuit designator) eliminate crosstalk.
• Surface-Mount Gull Wing Termination: Facilitates easy PCB integration with a 1.27mm terminal pitch.
• Wide Operating Range: Supports -55°C to +125°C, with derated power up to 125°C.
• Compact Dimensions: 4.9mm (L) x 5.99mm (D) x 1.45mm (H) with tight tolerances (±0.1mm height/length, ±0.2mm depth).

GS4A011301BT Applications
