GS4A022491DBT Description

The GS4A022491DBT 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 2.49KΩ resistance and an absolute tolerance of ±0.5%, ensuring exceptional accuracy. The network operates over a wide temperature range of -70°C to +125°C, with a temperature coefficient of ±50ppm/°C for stable performance under thermal stress. Encased in a rectangular ceramic SOIC package, it offers 0.1W power dissipation per resistor (0.4W total) and a maximum voltage rating of 100V, making it suitable for high-reliability circuits. Its gull-wing termination and surface-mount design facilitate easy PCB integration.

GS4A022491DBT Features

• Precision Resistance: 2.49KΩ ±0.5% tolerance with ±0.1% ratio tolerance for matched performance.
• Robust Construction: Ceramic case ensures durability and thermal stability.
• High-Temperature Operation: Rated for 125°C with derated power up to 70°C–125°C.
• Low TCR: ±50ppm/°C minimizes resistance drift.
• Isolated Elements: Four independent resistors in an 8-pin SOIC package (4.9mm × 5.99mm × 1.45mm).
• Surface-Mount Ready: Gull-wing leads with 1.27mm pitch for automated assembly.
• Non-Automotive: Not PPAP-capable, ideal for industrial/commercial use.
